Professional Rackmount Design The rackmount-ready design not only gives the preamp a clean, professional appearance but also ensures seamless integration into standard audio racks Review: Value is OFF SCALE!! - This preamp does it all! It has a processor (tape) loop, a mono switch, a phono stage, multiple tone adjustments and it sounds great! The only complaint that I have is that the ground wire for the phono input is located on the opposite end of the back panel from the phono input plugs and requires a separate ground wire (not the ground wire with the phono cable). Having said that, I hasten to add that the phono stage is dead quiet without a ground wire attached, at least in my system. The phono input can sound a bit bright as well, but there are multiple tone control adjustments available, so one can customize the sound; set it and forget it. The mono switch is useful if you're playing mono LPs. Likewise, if one has a tape recorder or an external processor that you'd like to switch in-and-out, then the tape loop (which, sadly, along with the mono switch, is an almost extinct feature today) is very useful. This is a "traditional" preamp, so don't expect Bluetooth connectivity or digital inputs and you definitely will not be disappointed. Review: Best in Class (price and quality ) - This is a quality built product. I have to air my grievances about having the rack ends on the product. I will not remove a star for that aesthetic because I'm sure people use it in the rack. Anyways I was having trouble with my mixer to my avr . Now no issues. Great loud signal for all my sources. Strong metal casing and knows that I now use before any other knows. These are now my main knobs. OSD is a company I trust now . This is a superior product in its class for the price point . And anyone needing a signal boost that's clean and powerful for under 200. Can't be beat . ## Features - DESIGN: OSD Audio’s Pre-1 is a unique preamplifier that accomplishes the subtle audio tasks that takes an ordinary audio source management to the next level. - SOUND QUALITY: The Pre-1 assists in experiencing a true home theater surround sound. It allows the ear to hear every detail for an enhanced audio environment. - POWER: A low frequency filter gives a response of 5Hz-30kHz +0 -3dB in order to have the ultimate powered preamp for a home recording or stereo system. - CONTROLS: The front panel has adjustable mic level control, input selector, microphone jack output, and mute option. It controls the bass for midrange, treble, loudness and balance control. - SIGNAL: A preamp is an important element for music recording to boost the low-level output on microphones. It provides a better recording signal compared to standard equipment. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MPYJLPX | | Best Sellers Rank | #52,323 in Electronics ( See Top 100 in Electronics ) #34 in Audio Component Preamplifiers | | Brand | OSD Audio | | Brand Name | OSD Audio | | Customer Reviews | 4.4 out of 5 stars 379 Reviews | | Manufacturer | OSD Audio | | Model | PRE-1 | | Mounting Type | Surface Mount | | Number of Channels | 2 | | Package Type Name | Retail Box | | Part Number | PRE-1 | | UPC | 819603012446 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** OSD Audio - **Manufacturer:** OSD Audio - **Mounting Type:** Surface Mount - **Number of Channels:** 2 - **Package Type Name:** Retail Box ## Images ![OSD Audio Pre-1 High Definition Preamplifier – Multi Source Select Phono Ready - Image 1](https://m.media-amazon.com/images/I/51PKGF7MqTL.jpg) ![OSD Audio Pre-1 High Definition Preamplifier – Multi Source Select Phono Ready - Image 2](https://m.media-amazon.com/images/I/51NUr0rRObL.jpg) ![OSD Audio Pre-1 High Definition Preamplifier – Multi Source Select Phono Ready - Image 3](https://m.media-amazon.com/images/I/61LkYdIwqlL.jpg) ![OSD Audio Pre-1 High Definition Preamplifier – Multi Source Select Phono Ready - Image 4](https://m.media-amazon.com/images/I/41qACcToOUL.jpg) ![OSD Audio Pre-1 High Definition Preamplifier – Multi Source Select Phono Ready - Image 5](https://m.media-amazon.com/images/I/31DKOsPz28L.jpg) ## Questions & Answers **Q: What are the specs on this preamp? what is it's s.t.n.r. on the cd output and what is the t.h.d. percentage?** A: From the manual Input Sensitivity/Impedance Mic 0.5V/600 Ohms Phono 3mV/47k Ohms Tape,Tuner, CD/DVD, Aux 150mV/47k Ohms Output Level/Impedance Tape Rec 150mV/100k Ohms Pre Output 500mV/47k Ohms Total Harmonic Distortion Mic less than 0.4% Phono less than 0.4% Tape,Tuner, CD/DVD, Aux less than 0.2% Signal to Noise Ratio Mic more than 50dB Phono more than 70dB Tape,Tuner, CD/DVD, Aux more than 80dB Frequency Response 5Hz - 30kHz +0 -3dB Tone Control Bass ± 12dB @ 100Hz Midrange ± 6dB @ 1kHz Treble ± 12dB @ 10kHz Loudness Control +4/0/+2dB @ 100/1k/10kHz Power Requirements AC 120V 60Hz / 220V 50Hz Dimensions 18.9" x 2.36" x 8.25" **Q: Funciona para poder subir el volumen a mi tocadiscos?** A: Si lo sube, aunque muy poco ya que distorsiona No me dio la mejora esperada, gasto inútil **Q: It is possible to amplify or equalizer the output earphones of one old tv to couple my yamaha r-s700 (3.5mm to rca connect)** A: You could equalize (Bass/Midrange/Treble/Loudness/Balance Control) coming in from the TV, and then output from the Pre-1 to input of your choice on the Yamaha receiver. **Q: Are the rack ears removable?** A: No. AND the unit is not 1 unit high or 2 units high. It’s somewhere in the middle and as such, there will always be a space between this preamp and anything mounted above. Not a good look. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Value is OFF SCALE!! *by G***T on October 14, 2019* This preamp does it all!

I have to air my grievances about having the rack ends on the product. I will not remove a star for that aesthetic because I'm sure people use it in the rack. Anyways I was having trouble with my mixer to my avr . Now no issues. Great loud signal for all my sources. Strong metal casing and knows that I now use before any other knows.

Can't be beat . ### ⭐⭐⭐⭐ Works just fine *by L***Y on November 29, 2023* Just set this up. First off, it shipped timely, came well packed and arrived in perfect condition. Seller deserves 5 stars. Now for performance. (This is being used with a solid state Kenwood M1 -100 watt per channel power amp running through Klipsch Icon KB-15 bookshelf speakers hooked to a Klipsch sub-woofer, just for reference) All inputs function properly. All controls function properly. Sound is fine, nothing exceptional, but fully satisfactory for a preamp of this price. Separation is fine, depth is fine, tone is fine, again nothing exceptional, but very satisfactory. So for basic performance everything is doing what it should and how it should. The fine details: As mentioned in othe reviews, the volume knob is extremely touchy. With my 100 watt amplifier I don’t turn it up past 1/3 of total volume, and it is detented so getting the volume where you want it is difficult. ( solved this by buying a small in line volume knob to run between this pre-amp and the power amp. Cost about $12.00 on Amazon. Easy fix. Thanks to other reviewers for that heads up so I was prepared with my fix when I received this pre-amp). There is some low level cross talk from other inputs. ( just make sure that you turn off the other devices you have connected to this pre-amp and this is eliminated. In other words, even if you have the input for your CD player not selected, if you then select the input for your tuner, there will be a very slight sound from the CD player still coming through. Solution is don’t play you CD player while listening to your tuner, and don’t leave the tuner on when listening to the CD player, etc. A bit inconvenient, but not a deal breaker. Again thanks to previous reviews for that heads up. So, all in all, this item is exactly what I expected. It is a basic fully functional pre-amplifier that functions as it should and as I expected. For the money, it can’t be beat ( not to mention that there is no other pre-amplifier even made or sold in this price range). So if you are only looking for exactly what this is, and you don’t want to pay a minimum of $1000.00 for the next least expensive pre-amp out there, this is your next pre-amp. The only one made, the only one sold and the only one available to function as an acceptable pre-amp for your stereo setup. Hope this helps others in the same quandary that I was in when considering this purchase. ## Frequently Bought Together - OSD Audio Pre-1 High Definition Preamplifier – Multi Source Select Phono Ready - Tan QY 2RCA to 2RCA Cable 3Ft, Gold-Plated 2 RCA Male to 2 RCA Male Stereo Audio Cable for Home Theater, HDTV, Gaming Consoles, Hi-Fi Systems (3Ft/1M) - Monoprice 1.5ft Premium 2 RCA Plug/2 RCA Plug M/M 22AWG Cable - Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.mx/products/36137632-osd-audio-pre-1-high-definition-preamplifier-multi-source-select](https://www.desertcart.mx/products/36137632-osd-audio-pre-1-high-definition-preamplifier-multi-source-select) --- *Product available on Desertcart Mexico* *Store origin: MX* *Last updated: 2026-05-26*
