Features and Specifications:
The OSD-AMP300 will take your surround sound audio from "nice" to "whoa" and is the perfect heavy-duty power amp for home theaters and whole house audio systems. This is a high current (2 Ohm Stable) two channel power amplifier that is overload stable. Overload stable means that if the amp senses too much current, it will cut back on the current but still run. This is a better alternative to just shutting down suddenly. It's ideal for use as a remote amplifier or as a single or dual zone amplifier and will give you more than enough power. It's all muscle but this amp has the finesse and features of some of the world's priciest designer amps.

The first thing you'll notice about the OSD-AMP300 is the ultra study build quality and beautiful finish. The illuminated voltage meter is also a nice touch that looks great in A/V equipment racks. Customers who purchase this workhouse of an amp love the built like a brick construction, and appreciate the the high end features found in amps that cost three or four times more. Features particularly favored by professional AV installers include 150 watts RMS per channel with complete custom installer feature set, built-in dual voltage meter, bridgeable outputs for 470 watts RMS total output power, dual line-level inputs with priority override and auto-on signal sensing circuit/12-volt trigger.

• Built in dual voltage meter
• 150 watts RMS per channel power amplifier with complete custom installer feature set
• Bridgeable outputs for 470 watts RMS total output power
• Dual line-level inputs with priority override switching - perfect for custom home audio distribution
• 2 stereo low-level (RCA) inputs and one high-level (speaker) input, and one auxiliary low-level output
• Auto-on signal sensing or 12V trigger; rear panel master level controls
• High current capability -- stable into 2 ohm loads; A/B speaker switching
• Auto-on signal sensing circuit or 12-volt trigger on
• Two sets of speaker outputs selectable from the front panel
• Rear mounted L/R main volume controls with front mounted volume and balance trim controls
• Flexible Power-on: Switched, Signal Sensing, and 12v trigger

Our Amp300 will handle this application, no problem.

By Kory from Omaha, NE on September 12, 2012
I am finishing my basement, and trying to figure out best set-up for speakers, equip, etc. I plan to have roughly 6 different zones (living room, bar area, 3 bedrooms, and outdoor). After running my speaker wires, how do I set-up from there? Do I need a receiver and an amp? I assume I hook up all speakers into amp, and then that hooks up to receiver? Also, where does my speaker selector fit in....where is that wired? Do I need a certain type of receiver to handle this many speakers and zones? HELP.....I'm obviously a novice!
By Customer Service - Q&A on September 14, 2012

Hi Kory,
The speaker selector goes with the amp and receiver. Take a look at our 6-zone kit in 'whole house audio, then 'multi-room audio.' Basically, you run the speaker cable from the speaker to the volume control for each zone. Everything is then connected to the speaker selector which is connected to the amp, and the receiver is the audio source—all in one general location. Call or email us for more advice or if you have more questions. Info@outdoorspeakerdepot.com - 1.888.779.4968

By Ken from Alameda, California on September 13, 2012
I am looking at setting up indoor and outdoor speakers at a golf course. I am looking at 4 ceiling Ice 650 speakers inside the golf shop and 4 AP 650 speakers outside on patio by putting green. I want an amp that has ability to power good volume (not just background level) for special events outside and also be able to have three volume zones to control sound levels. Would the AMP 300 be best option or something else? Also what other accessories will I need?
By Customer Service - Q&A on September 14, 2012

For up to 8 speakers total, you can use the AMP200 with the DSM4 and 4 volume controls (inside svc300 and outside ovc300). This would give you all the volume you are looking for. Each volume control is a 12-step knob style.

Great amp the only issue is the lights on the LED meters stay on even when amp is off line. Any way for these lights to turn off as well?
By Customer Service - Q&A on September 19, 2012

Hi Mike,
Glad you like the amp. The status bar stays on during normal operation, even if no source is playing. The only way to turn it off is to turn off the amp. If the light bothers you while watching a movie, you can always cover it but there is no switch to disengage it.

By Michael Woods from Muskoka, Ontario, Canada on March 11, 2012
I have bought a small resort. We want to run one sound source in the restaurant and one sound source in the bar and patio; all controls to be set up and contolled from behind the bar. I have purchased a 2 channel 5 zone speaker controller. We will want to run either satelite or internet sources plus an ipad dock. Total sets of speakers on each channel will be 8. Will two of these amps be enough power for each channel? Thanks for your help.

By Customer Service - Q&A on March 11, 2012

Hi Michael:

Based upon your application I would recommend an AMP300 per each location. One for the Resurant and one for the Patio/Bar. I am a little confused on application for the single 2 channel 5 zone speaker controller. I would have recommended going with our SSVC4 Speaker selector per amplifier. That way you can connect four pairs of speakers for both the Resturant and the Bar/Patio locations. The SSVC4 features Internal Volume Controls for each pair of speakers while controlling the impedance back to the amplifier. This would give you additonal control from the central location. You could then have a dedicated source connection to a computer (for Itunes or streaming media) using a Y adaptor to split between the input 2 of each amplifier. You could then have the option of plugging the iPad into either amplifier Input #1 and when you play it would take priority over the other source. These Amplifiers are very flexible and appear to be a great fit. We can also help you out with any of your Speakers and CL3 rated speaker wire needs as well. Thank you for considering OSD Audio.


By Joe from Sydney, Australia on June 30, 2012
Would someone let me know if this Amp (AMP300 M16) comes with a remote control please.
Thanks. Joe
By Customer Service - Q&A on July 2, 2012

Hi Joe,

There is no remote control that directly controls the AMP300 because in most applications, it connects to an Audio Video receiver to power second zone outputs. In these cases, you would depend on the receiver’s remote to control source selection and basic functions. When connecting directly to an iPod or iPhone, some customers utilize a docking station that features a remote that controls basic functions as well. The amp does feature a 12-volt trigger so it can be connected to a receiver that can turn the amplifier on/off . The amplifier also features an auto-sensing option so it will turn on and off automatically when music is present.

So, no TL

I have the AMP 300 300W hooked up to my Yamaha RXA2000 and use it to power my home surround system (10 speakers) via Yamaha multi zone function (Zone 2). Both are located in my basement and not easily accessible. Unfortunately, when I remotely shut down the Yamaha receiver, the AMP 300 stays on. Is there any way to turn the AMP 300 off w/o having to manually go to my basement and shut it off? If not, if I leave the AMP 300 on all the time will it damage the AMP or my Receiver? Also, does the AMP use a lot of electricity if its left on 24/7/365.
By Customer Service - Q&A on October 1, 2012

Hi Joe,
Your best option is to take advantage of the "auto-on" feature. This will allow the amp to go into sleep mode when not in use but be ready when you want to use your system without having to physically turn it on each time. The switch is on the back and you select "auto-on" vs. "normal" mode. Keep in mind, however, that the lights will stay on even though the amp is "sleeping" in standby mode. Standby mode uses very little power so that should not be an issue.

By Tim from Atlanta on January 21, 2013
I just purchased a home that is wired for 18 pairs of speakers in 15 different zones . The previous owner removed everything, and I mean everything. I have 8" round cutouts in 13 zones (all ceiling), 6"x10" cutouts (2 pairs) in one zone, and I'm wide open for 2 outdoor pairs for a very large deck/pool area. Each area appeared to have it's own volume control and wires are still present. I have a Yamaha HTR 5440 receiver I would like to connect to an Apple TV for streaming Itunes through my WiFi, but the receiver has no Optical Out to feed an amp(s). I only need background music for all of the zones except for the 2 outdoor pairs. Any suggestions?? On a tight budget!
By Customer Service - Q&A on January 28, 2013

Hi Tim,

Based upon you cutouts, you will need 6.5" in-ceiling and 6.5" in-wall. We recommend our Pro series as your best performance for the money (ICE640 In-Ceiling and IW680 for the In-Wall). Are there volume controls in each room or are the wires run directly to the speaker location from a central location? They may have taken the volume controls as well. It is important to know if the system had volume controls to determine the best speaker selector for your application. If you did not have volume controls, we recommend two TSM8 speaker selectors and two of the OSD AMP200 to power each speaker selector. Connect the two outdoor speakers directly to the B output of one of the amps with the speaker selector connected to the Speaker A output. The amp would get an analog feed from the APPLE TV which has the internal DAC converting the digital to analog signal.

By Jeff from Atlanta, GA on May 7, 2012
We just bought a new house with speakers (and volume control switches) in 8 areas. Ideally we could select from a few different sources (computer, TV, iPad) and limit what areas got what (one area with TV while another listens to music).
Will this amp work?
What speaker selector would you pair with it?
Any chance I can replace an volume control with a pad that can control the music (I am reaching here...)?
By Customer Service - Q&A on May 8, 2012

We sell the AMP300 in both our 6 and 8 zone kits- In the 8 zone we group it with the ISS8- This would allow you to have two sources plugged in at once and listen to one or the other.
Take a look at our MX1260- it is a step above the amp and speaker selector system, allowing you to connect 4 sources and listen to them simultaneously. Although it is only for size zones it might work out better for you finding a different way to power that 8th zone.
Also if you have the option of running cat5 - the digital keypads on the Breath Audio and Channel Plus systems we sell in our whole house audio section are superior. So if you have some time give us a call @ 1.888.779.4968 if you have further questions
By Customer Service - Q&A on May 8, 2012

Hi Jeff:

Before you get started you need to examine one of the Volume Controls that are in the wall. Remove the knob and face plate pull it out of the j-box and see if there is a impedance matching setting. Best if you can actually take a couple of digital pictures of the Volume Control. This will tell us how the current system was configured and what we need to do going forward. It would help if you describe the speaker configuration and take a picture where the system will be setup and how the wires are home run back to the central location.


By John from Boston, MA on March 17, 2012
I have in-ceiling and in-wall speakers connected in 6 zones / areas of the house. I would like to play music throughout the house from one source (connected via iPad or iPod). What set-up do I need? I do have Martin Logan speakers
By Customer Service - Q&A on March 17, 2012

Hi John:

Can you let us know how your current system is configured? Regarding your in-ceiling and in-wall speakers are they connected with a dedicated control system like a NUVO or Russound whole house audio system. Or is it connected using a speaker selector with volume controls in each room to control the impedance matching. You mentioned Martin Logans, is that your main speaker for listening and do you have additional speakers throughout for background music? The OSD AMP 300 is a High Current Amplifier that provides maximum flexibility for intregrating into a system while providing true audiophile sound quality. But please tell us more, I am intrigued by your teaser.

Whole house audio workhorse
December 13, 2013
I've been using my Amp 300 to run my whole house audio system for over a year now and am very pleased. I run channel A into an SSVC4 speaker selector and channel B into a second SSVC4. The signal comes from a Yamaha RX-V671 Zone 2 output. I don't always have all 8 pairs of speakers on but when I do there's never a problem. Don't let 0.2 % THD discourage you. Human ears can't discern less than 2%. This is 1/10th of that! Great sound!

I purchased the amplifier last august as part of my preparations for a home audio system during construction of our new house. The ceiling speakers were mounted then and i organised to purchase this amplifier at the same time.[...]I cannot recommend their pricing [...] highly enough. i've finally got the system set up and it sounds fantastic. The amp is driving 4 split sets of ceiling speakers in the house and managing this without any problem at all - in fact I've had to set the output way down! i've never been happier with a purchase than my recent experience with OSD

February 13, 2011
I purchased this amplifier to run a pair of the A830 outdoor speakers. I was leery about purchasing this amplifier because I couldn't really find a good review of it and it also has a noise rating of "less than 0.2% THD N" when I ordinarily never purchase an amplifier with a rating of anything above 0.0x% (x being a value of 1-9). One thing I did find odd about the amp was that the "Master Level"? of both channels was turned all the way down to low, or off, thus making no sound come from the speakers when I started testing the amp. Once I noticed this setting I corrected it by turning both "Master Level"? channels up to the middle. This middle setting produced enough volume to make the A830 patio speaker loud enough that the neighbors were looking out of their windows. The A830 at this volume were clean, no distortion, and I couldnt be more pleased with this amplifier.

Well, what can I say... I really enjoyed my experience with OSD. Not only did I place my order 4 days before Christmas, they actually emailed me, and spoke to me on the phone, over the holidays to ensure my product would be shipped in time. I purchased a sizeable amplifier, and two nice speakers for our back deck... And the quality is simply great. The amp, is built more solid than my 1500$ Harmon Kardon receiver, with a 4mm thick aluminum front panel, and good quality caps/EMI shielding on the inside. These guys were even a pleasure to deal with, as I live outside of the US, they called me (on their bill) to discuss ways to make the ~600$ shipping, MUCH cheaper. We ended up getting shipping down to 200$, for a 97lb order. I was very pleased... and would order from them again.

AMP300 Review

by Robert Archer

OSD Audio is one of the industry's hidden gems. This relative newcomer offers custom installers speakers, amps, cables and other accessories at price points that won't blow up a client's budget.

Under its Jazz Audio brand, the company sent me an OSD-AMP300 amplifier this past winter. This affordable two-channel amp offers 150-watts per channel, a bridgeable output that delivers 470 watts RMS, rear controls for independent channel gain, 12-volt triggers and dual-line level inputs with priority override.

Using the amp to power a set of two-way AC-16e outdoor speakers from Terra Speakers, I hooked a set of in-wall Transparent Audio cables from the amps rear binding posts to a wall plate dedicated for the speakers. Next I connected an iPod dock to the priority number one analog input, and then connected an AM/FM tuner to the second input.

After running the gear for several brisk weekends from early March into April to allow it to break-in, I was ready to take a closer look at the amp.

The amp impressed me for a number of reasons. Number one, its construction and performance for the cost. The modest MSRP doesn't hold back the build quality of the amp; it feels sturdy and it's heavy when installing. Looking through the top panel vents reveals a good-size transformer that is part of the reason why the amp was unfazed by driving the speakers to solid levels without breakup or distortion.

Second, it simply sounded good. I thought the OSD-AMP300 maintained nice control over low-end and mid-range frequencies. For octave-to-octave capabilities, I thought it was smooth in reproduction of mid-range and treble content without overemphasizing or underplaying any particular band. Through the Terra speakers, the system also imaged well with a both low-resolution AAC and higher-resolution AIFF digital files. Often imaging can suffer with low-res content, and adding the variables of an outdoor listening environment potentially makes that situation worse, but not here.

Of course, power is an important part of any good amp, especially one that's going to be used for outdoor audio. I put the OSD-AMP300 to the test with what I've experienced to be power-hungry Terra speakers. I've tried a good, but small, integrated amp and a home theater amp that employs Class-D power and found the integrated product shut down under the Terra's current demands and the Class-D struggled to play at reasonable sound pressure levels. The Jazz unit, however, handled my requirements without a problem.

Given today's economic climate, it's important for an installer to present value-minded propositions. The Jazz Audio OSD-AMP300 may not have the style and refinement of a Krell or Bryston for that high-performance two-channel system, but it offers many of the same high-power traits as these benchmark products at an extremely reasonable price point.
