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 dog barking, 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 is 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.

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 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 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 '' 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 Pre-Amplifier is as solid as it gets.

tom • 12/17/2019, 2:17:43 PM Q bluetooth? Do any of the products support bluetooth sound sources?
Customer Service • 12/17/2019, 2:17:43 PM
A 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
Ed • 12/17/2019, 2:17:43 PM Q Is there a remote control?
Customer Service • 12/17/2019, 2:17:43 PM
A HI ED: There is no Remote Control for the Pre One. Sorry about that. TL/4094
vin • 12/17/2019, 2:17:43 PM Q can I use this unit for 2nd channel on my VSX1124
Customer Service • 12/17/2019, 2:17:43 PM
A 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' tim@osdaudio.com TL/4106
Ryan • 12/17/2019, 2:17:43 PM Q Looks like the front panel of the unit is 18.9" wide but how wide is the back of the unit?
Customer Service • 12/17/2019, 2:17:43 PM
A HI Ryan: The measurement of the back Chassis is 17 5/8" TL/4109
Dennis Bellis • 12/17/2019, 2:17:43 PM Q 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.
Customer Service • 12/17/2019, 2:17:43 PM
A 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
