A preamp is a key component to experiencing true home theater surround sound and a critical element to recording music, yet few people really understand the function a preamp plays. OSD Audio’s Pre-1 is a unique and, yes, affordable preamplifier that accomplishes the subtle audio tasks that transform an ordinary home theater surround sound system into, ‘wow, I hear every detail,’ from a gun chamber being loaded, to the whooshing blades of a helicopter. A preamp delivers similar benefits to music recording by boosting the low-level output on microphones. Because mics generally have a weak output, adding a preamp will deliver a better recording signal level verses simply plugging the mic into a computer and standard recording gear. Preamps do more than add volume, however. Like the home theater experience, a preamp in recording can finesse the subtle “color” of sound by adding tonal quality. Let’s start with what a preamp is and then we’ll cover the attributes of OSD Audios’ Preamp-1 so you can make the wisest buying choice.

What Is A Preamplifier and What Does It Do?

Simply put, a preamp is a separate processor within the audio command chain that accomplishes detailed audio tasks. A decent home theater will typically have one or more amplifiers and an AV receiver. While an AV receiver has amplifier power, power is not its primary function. An AV receiver “receives” audio and video signals from a variety of sources (TV, DVD DRV, etc.) and routes the signals to the speakers. Power is where the amps kick, which supply the juice needed to move the signal with enough amperage so your surround sound speakers produce the best sound for which they are designed. That should be enough, right? Well, not exactly.

The amp may add power, but it can be a bit of a clod because that’s all it’s doing—add power. (Okay, audiophiles, we know it does more, but let’s keep it simple). Enter the preamp. A preamplifier is a low-level amplifier. What that means is that it takes a line level signal (that’s the strength of an audio signal used to transmit analog sound between audio components such as CD and DVD players, television sets, audio amplifiers, and mixing consoles) and amplifies it enough to drive the power amplifier to its rated output. If an amp is receiving a signal at its rated output, it will perform better and your surround system will pick up detail you never thought possible. The same can be said in sound recording where an audio interface enhances the sonic capabilities of a computer. While an audio interface includes an internal preamp, an external preamp gives you more control over tonal quality.

OSD Audio Preamp-1 Professional Home Stereo/Home Recording Pre-Amplifier

There are many preamp manufacturers that range from bizarrely cheap to bizarrely expensive. We look at our OSD Audio Preamp-1 Professional Home Stereo/Home Recording Pre-Amplifier as the middle ground, or an affordable preamp that adds front-end system control to two or multi-channel audio systems and home recording systems without having to load up on credit card debt. OSD Audio Preamp-1 Professional Home Stereo/Home Recording Pre-Amplifier is not shy on features for the price, and we encourage you do research the specs. Our preamp provides four selectable unbalanced analog RCA inputs, Phono, AUX1, AUX2 and CD/DVD and a ¼” Mic input jack on the front panel with adjustable mic level control. Other front panel variable control knobs feature three tone controls: Bass, Mid and Treble, plus Balance, Master Volume and Loudness Contour Knobs with Min to Max settings. Additional front panel controls include Power Switch, Tape Loop, Mono/Stereo, Low Filter and Mute Buttons. We back this preamp with a 2-year warranty because the Preamp-1 Professional Pre-Amplifier is as solid as it gets.

Can I use this with the 

Pyle PT8000CH 19" Rack Mount 8000 Watt 8 Ch Amplifier?

1 Answer
Hi Dennis:

Yes, the Preamp1 will work with this amplifier. It can connect to the Bus or Aux inputs, so you have two Aux, one CD/DVD, and one Phono Inputs so you can play on all four zones. You have a choice of Bus-Aux or direct Line input. You could even connect multiple Preamp1 depending on how you configure the three inputs per zone. It will add gain to whatever source you would connect to and also has a built-in Phone Preamp in case you are using Moving Magnetic Cartridge. There is also a Mono/Stereo switch, Subsonic low pass filter, Mute switch, and even a Tape Monitor, which you can add an equalizer to your rack.  There are also bass, Mid, Treble, and Loudness contour switches. Plus, a Microphone input and level control. And it features integrated Rack Mount front panel.

February 3, 2020
I just purchased the pre amp and was thinking it would hook up to my Yamaha RX-V679 AV receiver. How can I hook this up?
1 Answer
Hi Ray:

You would connect the Preamp-1 to your Yamaha RX-V679 with an RCA Stereo Right and Left Patchcord. One end would plug into the Pair of RCA connectors marked Output (the pair on the right side) The other end of the patch cord would connect to Audio 1 or Audio 2 if you are already using Audio 1. You can switch whatever is connected to Audio 1 and Audio 2 to either Aux1, Aux2 or DVD/CD. The Phono input is only for adding a turntable. There is a built-in Phono Preamp for MM (Moving Magnetic Cartridge). Please let me know if you have additional questions;

Is there any fan noise associated with this pre amp????
1 Answer
Hi Karl:

There are no internal fans associated with this unit. You are only dealing with signal level not speaker level. An amp will generate internal heat based upon the load created on the output side of the Amplifier, not on the input side from the PreOne.

I looks like most patch cables treat these as stereo plug to a mono connector. I am capable of building my own cables if need be. Do I require a special box or fancy matching plug thingy?

Will this preamp work with marantz 7025 power amp. Many thanks
1 Answer
Hi Marcel:

Yes, the Preamp1 will work with your Marantz but note that the internal Phono preamp is limited to MM, a Moving Magnet Cartridge. The problem will be locating a new preamplifier that would have a differential output so you could run Balanced Line connectin to get the full potential of the Marantz. I found a $400.00 Rotel with XLR outputs on eBay. Typically, it would cost more than MDF price of your amp to find another Balanced Line solution (even a used one at that).

February 16, 2019
Hello, I have this preamp and the osd amp 200 driving four Bose 251’s and two monoprice outdoor speakers out by my pool. This is being fed into a niles ssvc-6 speaker selector and volume controller from the osd amp 200. I want to add your smp500 to the mix so I can power two of your unground subwoofers. How do you recommend that I connect the smp500? I will mostly be using an Apple airport express as my source, and ultimately be using the volume control built into the phone to control the volume, since the media cabinet is in my garage. Will this cause any issue with the volume when everything is put together?
1 Answer
Hi Dustin: You have a couple of choices where to connect the SMP500. You mentioned you have two pair of BOSE and a pair of Monoprice outdoor speakers. I am assuming each pair of outdoor speakers connect to a dedicated Zone of the Niles SSVC6 Speaker Selector. And you most likely have speakers connected to the other three zones. The first option is to join the SMP500 to the Line 2 Output of the AMP200 using an RCA Stereo Patch cable. Whatever plugged into Line 2 Input will pass thru to Line 2 Output. This will work if all you have connected is Line 2 Input and nothing plugged into Line 1. There is no dedicated on/off for Line 2, and it will play even if you have something playing from Line1 that takes priority over Line 2 Input (if your Source is still playing). The second option involves wiring from Speaker B to Speaker Level input on the SMP500. You have the B switch on the front of the AMP200 allowing you to turn the subwoofer off when your not playing your outdoor speakers. You can use 14 gauge to connect the AMP200 to the SMP500. But use 12 gauge to connect to the two inground Subs. If you need further clarification; TL/5415

Hi George: I am a little confused about your system. Do you have a Bluetooth Turntable that has a built-in Bluetooth Transmitter that is sending a wireless audio signal to your 5.2 AV Receiver?

Hi, I already ordered one and its now on the way for delivery. Im thinking of adding an equalizer on it. How is the wire connection to connect an equalizer, and what equalizer do I need to purchase that will work on it. Thanks. Ronel P. Honolulu, Hi
1 Answer
Hi Ronel: Connecting a two-channel stereo Equalizer to your pre-one preamplifier is very easy. It connects to the Tape Loop of the Pre-one using two RCA Stereo patch cables. The first connection is from the Rec to the input jacks of the EQ. And connect the output jacks of the EQ to the Play jacks of the Pre-one. As far as two channel EQ to use with the Pre-One, it will have to have an unbalanced connection (RCA). Typically it will be 15 bands; 2/3 octave and be under 125.00 dollar cost, Check out the Berringer Mini FBQ800 around $69.00. There is also an ART EQ341, and they have three models under the 400 series as we including two 1/3 Octave units. Good luck TL/5382

HI Mar: The Pre-One will work with the Crown amplifier. The Pre One has an unbalanced connection. It has all the features including four inputs one being a phono input with a Phono preamp for an MM moving magnetic cartridge. It also has a tape loop for an Equalizer and Mic mixer input. It depends how critical your application is for sound quality. You lose 6 to 10dB and virtually no noise by not connecting with a preamplifier with Balanced Line differential connection.

Hi Frank: The fact the Phono input has dual RCA (right and left) plus a ground wire tells me it has a Phone preamp for at least an MM cartridge. There is no switch to choose between an MM and an MC cartridge. I am trying to confirm with the factory.

I am interested to know if this pre-amp can take (input) turntable and cd player signals and output at line level with enough amplification for connection to a Sonos connect? The idea is to interface my old audio equipment with a new Sonos speaker system setup in several rooms throughout my house and not only work, but sound good at various volume levels. Thanks.
1 Answer
Hi Steven: The new Pre-One would be an excellent addition to your application. As you may know, the SONOS Connect features a right and left RCA stereo input that would connect with the Pre One allowing you to add a phone, CD player and two additional inputs. It also has a mic mixer (a 1/4" input featured on the front panel) input as well. You also have Bass, Mid, Treble, loudness and balance control knobs plus Mono/stereo switch and Low filter switch. Note the master volume control has 1.5V maximum gain compared to the typical 500mv output of other components. The SONOS and Pre-One would be ideal for you.

from Oregon asked:
November 19, 2016
I have paired this unit with your AMP200 power amp, and I can't get them to work together, are these two unit non-compatible? I have tried everything possible with no luck.
1 Answer
Hi Dennis: They should work fine together, first you must determine if the AMP200 is setup properly. I mean does it work on its own with your anyone of your sources plugged directly into Input #2? You need to turn the volume knob on the front panel to fully open (as far as it will go turning it clockwise). Make sure you turn on option is set to normal (right next to stereo bridge switch set to stereo). Then turn the switch on the front to on. Set the delay knob all the way counterclockwise to 3 seconds (next to the Line 2 output). Check the master volume knobs, I believe they are turned all the way counterclockwise or min. Turn your source on then adjust these knobs turning them both clockwise until your start to clip or create distortion now dial them back an 1/8 of an inch. Make sure your source volume is turned up to standard listening levels. Once you have determined the AMP200 is working then it is time to unplug your source from the line#2 input of the AMP200 and plug the source into Aux#1 of the Pre1. Then connect the Output (far right L&R RCA) on the back of the Pre1 to the Line 2 Input of the AMP200 with a stereo RCA patch cord. Now go to the front panel of the Pre1. Make sure input select is set to Aux 1. Then check the four buttons to the right of the input select, Tape should be disables (out), Mono disabled (out), low filter can be enabled (in) and Mute disabled (out). Make sure volume knob on the front of the AMP200 is turned to the middle just like the balance knob. You should now control everything through the Pre1 including bass , mid and treble and master Volume. Loudness is only used when listening to lower levels where it compensates the bass. Make sure power switch is pushed on the Pre1 and they should work together. The AMP200 should light up blue when playing (red in stand by) and the red LED should be on for the Pre1. Let us know if that helps. TL/4129

i have a jensen turntable jta230 with its own amp in it 13 watts its doesent get loud enough 13 watts will this one work with it and it only has 2 line in and out ports thank you thomas r schmidt
1 Answer
HI Tom: This Pre Amp only has 500 Ma Gain stage, so its not going to add enough to make a difference. You can try adding both a Pre One and our XMP100 Amplifier. That combination will give you plenty of output. TL/4523

How much gain does this preamp have? What would be the max output voltage of a line level input?
1 Answer
HI Rigos: Only 500mV (spec is in owner's manual), the problem is that it would have doubled the cost and delayed shipment to add a higher pre out. This is a great value but I had wanted to jump it up to 1.5 Volts. Good question, TL/4450

Looking to use something like this as a cheap solution for a source switch before an EQ and then power amp. Does this one have a higher output for phono as normal on most receivers?
1 Answer
Hi Pete: This will work perfect for your Equalizer, just connect to the tape loop play/rec. The Phono is a loaded question. This does feature aground connection so it is a true phono input but we like to call this an affordable entry level unit (Cheap sounds like just that... cheap) But it is all relative so it would be an entry level phone pre amp as one of the four sources. We like to add it to our two channel amplifiers to handle the front end. TL/4268

1 Answer
Hi Steve: .5 Volts or 500 mill amps. In order to increase the voltage output of this design the priice would have more than doubled with the tooling and certification. TL/4226

The Front Panel Mic Input. When hooking a microphone to it will I be able to speak and play music from any of the Aux inputs at the same time. Use- Fitness instructor with wireless head set into th e front mic jack and wifi/bluetooth reciever into Aux 1, source ipod.
1 Answer
Hi Raymond: That is the concept, the two channels are mixed at the same time the mic input and whatever input you select either DVD/CD, Aux 1, Aux 2 or Phono. You can set the level for each independently with the Mic volume or master volume that controls the other inputs. TL/4201

if I use this preamp with a musichall turntable 5.3 ,will I get a hum
1 Answer
Hi John: The Pre1 is an entry level Pre-amplifier that maybe over matched for your turntable. It does feature an internal phono pre amp and ground connection which is supposed to eliminate the hum. Maybe it be worth a try, we do have 30 day performance guarantee (save your packaging). TL/4181

from new york asked:
November 2, 2016
can I use this unit for 2nd channel on my VSX1124
1 Answer
Hi Vin: You can use this with your Zone 2 Pre amp output but will need an internal amplifier as well something like our AMP200 to provide power. The Pre amp only has signal (low) level connection and comes between your Pioneer AVR and the Amplifier. Then depending on what else makes up the rest of your system you may need to add a speaker selector and possibly volume controls to do the impedance Matching in case you do multiple zones. Good Luck Please let us know what else we can help you with for the rest of your system' TL/4106

bluetooth? Do any of the products support bluetooth sound sources?
1 Answer
Hi Tom: We have Bluetooth Rocks, Frogs and Patio Speakers that all feature a Master Speaker and matching Satellite speaker that needs to be connected by a speaker wire. The Master speaker includes Bluetooth Receiver and internal Stereo Power Amplifier. It is connected to the power supply included in the kit. It is a direct connect to a single Bluetooth enabled device. There are a number of choices for external Bluetooth receivers that can be used with our Pre1 as one of the four potential sources. They start on-line at $14.99 and above, would recommend at least a Bluetooth 4.0. Good Luck TL/4049
