    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.

    Raymond Sigwart • 12/17/2019, 2:17:43 PM 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.

    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
    steve • 12/17/2019, 2:17:43 PM what does this put out as a signal? 1 volt 1.5 or 2 thanks
    Customer Service • 12/17/2019, 2:17:43 PM
    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
    Pete • 12/17/2019, 2:17:43 PM 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?
    Customer Service • 12/17/2019, 2:17:43 PM
    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
    Harry • 12/17/2019, 2:17:43 PM Are the rack ears removable? If not, is there an earless/ear-optional version available/on the way?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Harry: The rack Ears are incorporated in the front face plate. They are not removable. There are no plans for a version without rack ears, sorry about that. TL/4338
