9/13/2023 0 Comments Surround pre amp![]() That means that your turntable will not produce sound out of those speakers (it uses 2 analog channels). You should not expect to hear sound from the surround speakers UNLESS the input being used on the receiver is digital (coax, Optical, HDMI) and is also in 5.1 or 7.1 audio. If you only have passive, then you will have to get some way to amplify the sub preout signal (another amp, or a powered subwoofer). If you have a powered subwoofer, you can plug the Sub Pre out to it. Hook up the surround sound speakers to the speaker jacks on the receiver. You do not need an amplifier for the surround speakers, its built in to your receiver already. The surround pre-outs are for connecting to another amplifier so that more powerful speakers/amplifiers can be used to power the Surround channels. It will have all the high frequencies cut, its just the bass signal. The Sub Preout is for connecting to only a Powered Subwoofer. The red/black speaker jacks are for connecting speakers to it. The Pre-out RCA jacks on the back of the receiver only output signals, not actual power. ![]() We back this preamp with a 2-year warranty because the Preamp-1 Pre-Amplifier is as solid as it gets.Ignore what I said above, I think I confused you more than I helped. Additional front panel controls include Power Switch, Tape Loop, Mono/Stereo, Low Filter and Mute Buttons. 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. 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. 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. 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. There are many preamp manufacturers that range from bizarrely cheap to bizarrely expensive. While an audio interface includes an internal preamp, an external preamp gives you more control over tonal quality. The same can be said in sound recording where an audio interface enhances the sonic capabilities of a computer. 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. 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. (Okay, audiophiles, we know it does more, but let's keep it simple). 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. 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. An AV receiver 'receives' audio and video signals from a variety of sources (TV, DVD DRV, etc.) and routes the signals to the speakers. While an AV receiver has amplifier power, power is not its primary function. A decent home theater will typically have one or more amplifiers and an AV receiver. Simply put, a preamp is a separate processor within the audio command chain that accomplishes detailed audio tasks. 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. Like the home theater experience, a preamp in recording can finesse the subtle 'color' of sound by adding tonal quality. Preamps do more than add volume, however. 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. A preamp delivers similar benefits to music recording by boosting the low-level output on microphones. 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 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.
