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.

Is this unit switchable to either mc or mm turntable? Thank you.
1 Answer
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. The new Preamp-1 now has a 1.5V output which might make it work with the MC cartridges with their lower level output. We amend the answer and update bullet points. TL/5222

from IL asked:
September 21, 2018
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. My only question; what are you doing for the rest of the system. What amplification or distribution are you using or planning to add? Let me know if you need additional help. TL/5210

There are Audio Video processors that also feature 7.2 Preamp output option but start at $800 and up (check out the DENON AVRX3400H).

Is the center detent on the Loudness control "flat"? I understand turning it up towards max increases the bass and treble according the manual, but does the min setting decrease those frequencies? or is min the "flat" setting?
1 Answer
Hi Troy: If you look at the specs in the Owner's Manual you will notice `the Loudness is +4 or 2dB. Comparing that to the Bass, Treble and mid range knobs which ar +/- 12 db that tells me it is Flat at Minimum with no negative detent. TL/4896

I would like to be able to occasionally use this as also a headphone amp at low to medium listening levels, in my office setup. Is there enough gain pushing cd or cassette signals to power efficient headhones (about 32 ohms) such as Sennheiser HD 518s, using a RCA-to-female mini adapter? Thanks, Joe Smith, Des Moines
1 Answer
Hi Joe: The Pre One does not have a Headphone Jack (the 1/2" connection on the front is for a Microphone input. Sorry about that Note: I requested a headphone jack on the original design but it would have delayed release while adding additional costs. We are working on a step up unit that will feature a IR remote as well as headphone out put with a 1.5V output compared to the 500mV currently found on original unit. TL/4837

Hi, would I be able to use this pre-amp for the Bose F1 Model 812 PA speakers? If yes can a Bluetooth be added to the pre-amp? If no any suggestion?
1 Answer
Hi Kwadwo: Yes this will be compatible with your BOSE Fi Model 812 PA speaker. It would allow you up to four inputs, Phono, CD/DVD and 2 Aux inputs. You can add a independent Bluetooth Receiver. A good one will run you around $50 to $60.00. The Pre amp has a mic input but you would be better off using the internal mic input. The Bose has a unbalanced pair of RCA's that will connect directly to the Pre One as your line 2 input. TL/4798

Hi I think this is what I've been looking for but want to make sure. I have a Halfer 9000 amp I bought years ago and never got to use until now, I hope. Also I want to use my old Denon DP-51F turntable. My Hafler preamp bit the dust. Anyway I'm using a mm cart. From the manual I looked at looks like it should work fine. Please let me know. Thanks Tom Finn
1 Answer
HI Tom: It might work but the current Pre One has only a 500MV output so may not be high enough for your older components. We hope to release step up pre amplifier with a 1.5MV output which I would feel more confident in recommending for your application. It will raise the price a bit but will be relative to the increased in benefit. TL/4739

Hi I believe that I have researched the OSD system quite a bit, and dont see that it can be controlled by a mobile device. Is this correct? We have 6 speaker zones in our house, and like the features of the amp very much, but would like to be able to adjust each zone from our network. How do we do this?
1 Answer
HI Hans: Maybe you can submit your system into the OSD Upload Your Plans. We do not have an elaborate system that you can just plug and play but we have lots of components that can be configured depending on your actual application. You will need to submit a blueprint or basic diagram with the rooms and zones you want to control. Do you have a Custom Home Theater setup as well. Good idea combining the two using the AV Receiver as your streaming music control center. It also help to add as many images of your rooms/zones. And include where your you would want to store your equipment. Also note what components (electronics and speakers) that you might want to use in your system. Let me know; TL/4725

Hi. How can an equalizer be added with this preamp? Any diagrams and settings?
1 Answer
Hi Juan: I believe you can connect an Equalizer utilizing the Tape Loop. You have an input and output connection on your Equalizer. Same with the OSD Pre1. Note many of the current Equalizers have Balanced line in and out. These will not work with the Pre1. But if you find one with RCA unbalanced connections then it will work. When you want. This is from the Owner's Manual: Tape Play: Connect to a tape decks output jacks. Tape Rec: Connect to a tape decks input jacks. When you want to operate the EQ you will enable the tape loop. It will equalize whatever you select as your source (Either DVD/CD/ Aux 1, Aux 2 or Phono). Good luck... TL/4179

Dennis Bellis
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

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.

An Unbelievable Bargain in Stereo Components
I needed an affordable analog stereo pre-amp for a really old 125-watt (RMS) per channel AB-class power amp that's been packed away for a while. These days not only are preamps rare, they are ridiculously expensive, too. Searching around on the web I found a basic component that had all the necessary functions for under $100. Regretfully, it was hideously ugly with a purple and blue paint job on the front panel. Continuing to search I found its functional twin, the OSD Pre-1, with a conservative black front panel in the style of the great audiophile brands. Even better, it had a lower price. Because I live near the company in Brea, CA, I was able to pick it up and save any shipping charges. It's now hooked up and doing exactly what I need it to, i.e., input several sound sources, modify the tone of incoming signals, and regulate volume. It does all of these things without any quirks or audible flaws. As someone, who has owned a number of golden-ear-quality components, I was amazed by the build quality at this price point. The RCA terminals are gold plated and all of the knobs are real electromechanical potentiometers with detents. Plus, there is a turntable input that handles moving magnet phono cartridges, the most common variety. The flexibility to modify tones to the power amp is outstanding. In addition to simple bass and treble knobs, there are midrange and rotary loudness controls. Granted, these are not the same as a graphic equalizer. However, these features make it possible to subtly "sweeten" the output of any speaker in any listening environment when needed. I'm sure someone will grumble that there is no remote control. However, for a sophisticated, aspiring audiophile looking for maximum performance at a rock-bottom price, this is a non-issue. I noticed on the "Questions" page that there were concerns regarding the output voltage from the preamp to the power amp. In my set up it is not a problem. The preamp's output signal is adequately strong so that the overall system performance can be paint-peeling if the volume is really cranked up.
ProsGreat build quality, features and flexibility.
ConsAudio snobs will ignore this amazing product. Tyros will not understand why it is incredible.

Really good for the price
I'd really like to give this preamp 5 stars, but the volume steps are really annoying. While the unit is everything it should be and more for the modest price, the stepped volume control is ridiculous. One step on the volume is quite louder or quieter than reasonably acceptable. Fortunately for me, I am using this preamp as a cheap interim solution with some Crown amps and they all have controls on the front, so the gain can be controlled on them to make up for the disparity, but changing each when a new song is played is more hassle than it should be. Other than that, this amp is a huge bargain.
ProsExcellent build quality for the money Attractive design Plenty of inputs Excellent value for the price
ConsStepped volume control that is several dB difference between each step

Best For Price
I got the Preamp-1 to keep a system going while my Carver preamp is in the shop for repairs. If I were comparing to it, this puts out a third of the volume and more harmonic distortion... not that you're likely to notice. The sound is good, and the controls let you dial in your system the way you like. I've not heard anything close to it in it's price range. If you're on a budget, or just don't want to spend a fortune on a preamp - it's a great deal. There is no sub out on this pre... a set of "Y" cables took care of that. I will keep it even after I get the Carver back as a backup for all of my systems.

WOW what a surprise
Very nice unit. The sound is clean and balanced. Sounds as good as the $1000.00 preamp I had in the past.
ProsSounds like expensive like pre-amps that I have owned and listed to.
ConsThe selector knob pointer is not lined up exactly to the position that is selected. There is slight bleed over between devices on at the same time.when the one selected is silent and the other device is on but not selected. This only occurs when the volume is almost turned up to max. So have the other devices off to make sure there is no bleed over.

I have owned a number of both pro and consumer audio products over the past forty years. I am impressed by the quality and performance of this preamp. Total bang for the buck!
