SKU: OSD-AMP300
OSD AMP3002-Channel 350W Per Channel, High Current Class A/B Stereo Amplifier Toroidal Transformers
A heavy-duty 350-Watt A/B two-channel dual source amplifier for use as a remote or single amplifier.
Dual Source Switching
The AMP300 also includes dual source switching to connect two audio sources and toggle between them for greater listening flexibility. Automatic source switching switches between connected sources with a priority signal-sensing feature, so if a DVD player is connected to input 2, then you decide to stream a movie through a game console, when the console is turned on, the AMP300 automatically switches to that source. The AMP300 also includes a variable delay control that lets you adjust the amount of time needed to "listen" for a signal from your main input, between 3 and 15 seconds. This prevents gaps between music tracks from accidentally switching your inputs. This high power amplifier includes two RCA signal level inputs so with the addition of an RCA-to-mini stereo cable (sold separately), you can connect your smartphone or other device.
Plenty of Power for the Price
Pair our AMP300 with the power-hungry speakers, and the sound quality will transform your listening experience. Rated at 350 Watts per channel peak power (470 Watts Bridged Mono into 8 ohms), the AMP300 can be configured as bridged or stereo. In bridged mode, you can combine the left and right channels into one audio channel which bumps up the power to a whopping 470 Watts (8 ohms). When playing dual sources, switch to stereo mode which reduces the power to 350 Watts per channel. It is the only high current 2 ohm load stable amp in the market.
Features
The AMP 300 also includes two sets of speaker outputs with front panel controls, auto-on signal sensing or 12-volt trigger, rear panel master level controls, dual line-level inputs with priority override switching and dual voltage of 110V/220V and auto signal sensing. This amp has a clean, brushed metal front panel with a volume control, power on and off button and a balance control knob to adjust the balance between the left and right channels and dial in just the right sound level mix. Special protection circuitry safeguards the amp from a short circuit.

Will this amp work well with my DTR 40.6 receiver with 7.1 surround and how should I connect the speakers.
Customer Service • 12/17/2019, 2:17:43 PM
HI Keith:
It depends on if you are using your Integra as a Surround Sound Receiver and you want to add a second zone out put to control multiple zones connecting to the ZONE 2 Pre amp output. If this is the case you would connect the Zone 2 output to the Input#2 of the AMP300. That if you are using all 7 powered channels for your Home Theater and you want to power a Zone 2 with the Zone 2 Pre amp outputs. You can connect two speakers directly to the AMP300 (Speaker A/B) and have two zones. So you will need to tell me more about what you are trying to accomplish, how many zones, how many speakers etc.

I want to run 2xOMSUB200 with 8xLS3 using a Sonos Connect. How would I wire up the speakers to this AMP? Will the Amp automatically switch on/off when I turn my Sonos on?
Customer Service • 12/17/2019, 2:17:43 PM
Hi IMS:
I would connect your two OM Sub 200 in parallel to speaker A output from the AMP300.So with a four conductor cable like our CL14/4 wire both subs together R+, R-, L+ & L-. So you have 2 wires connected to each one of the four outputs. Next you will want to wire the 8 each (or four pair of LS3) in series parallel. Four speakers for the right and four speakers for the left. This will take a little patience and CL14/2 speaker wire. Contact me at tim@osdaudio.com so I can furnish you a diagram.
Good system...

Note, regarding your second question the AMP300 features three turn on options:
1) Manual, using the on/off switch on the front panel
2) Connecting a 12 volt trigger to your other component like a receiver.
3) Auto Sensing, goes into stand by after 5 minutes once there is no signal. Then comes back on instantly once it sees a new signal.
Note: in all cases the power switch on the front must be in the on position.

Can you use the left output as a mono signal for LFE for a separate sub woofer amp? Also does anyone know what the delay level switch is for?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Vincent:
The output from the AMP300 is not a true LFE (low Frequency Effects). I believe you can only get that output from a AVR Receiver with dedicated LFE output. The LFE by passes the controls of a dedicated sub woofer amplifier. Most AVR output a mono low frequency signal.
The Delay switch; this has to do with the time when you turn line 1 off and Line 2 comes on. It adjusts between 3 and 15 seconds. The problem is when you listen to line 1 and there is an extended silent passage the automatic source switcher will think line one has turned off and will now switch over to line 2 but as soon as the silent passage is over it automatically switches back to Line 1. The Automatic Source Switching is found on our lower end amps like the AMP120 and XMP100. The delay is less than 5 seconds and there can be issues with it switching prematurely to line 2. We added the adjustable delay to our AMP200 and AMP300 as an upgrade allowing you to set the delay up to 15 seconds. We typically recommend connecting to Line 2 input when connecting only a single source. Plus Line 2 output only pertains to whatever is connected to Line 2 input. It does not work with Line 1 input. So when you talk about connecting your sub amp it will only work for whatever is connected to Line 2 input.

So how the setup gonna go If wanna play same song from yahama receiver in all 8 zones through amplifier. PLease let me know how to connect the yahama receiver to amplifier and and speaker selector switch (dsm8) .Should I connect switch to yahama or the amplifier. ? basically I wanna play from yahama receiver and listern in all room. please let me know how to connect the stuff. I am bit newbie. Thanks

Hi Ruby:
The AMP 300 will be effective driving 8 external zones. The AMP 300 features both Hi and low level input. Your Yamaha Receiver really only has High (speaker) Level output so no Low Level Pre Amp output. The High level input reduces the input back to a low level pre amplified signal that is re amplifier inside the AMP300 Audio Section. In order to connect you would connect speaker wire from the Yamaha Speaker A Right and Left (+/-) to the Speaker in on the AMP300. You will need to make sure to connect the switch above to Line 2 (push to the right). The DMP8 would then connect to the Speaker A output of the AMP300. The Yamaha will then be a Pre Amplifier with all the connections you will need. It has four analog inputs and two digital inputs. Plus you will need to hard wire a network cable into the LAN connection.
Please let me know if you need additional help; tim@osdaudio.com
