Preface ASR-10 Musician’s Manual Amplification Connect the Main Audio Outputs of the ASR-10 to the line level inputs of a mixer, instrument amplifier, stereo, or any other sound system, using 1/4 inch audio cables. If your system is stereo, connect the Left and Right Main Outputs to two channels of your mixer, stereo, etc. If it’s mono, use either of the Main Audio Outputs, but make sure nothing is plugged into the other output. For listening through headphones, plug the phones into the rear panel jack marked Phones . If you’re running the ASR-10 through a mixer, in stereo, be sure to pan the left input channel on the mixer fully left, and the right input channel fully right.
It is a good idea to make sure your audio system is turned off (or down) when making connections, to avoid damaging speakers or other components. Note: The ASR-10 outputs are line-level, and are intended to be connected only to line-level inputs, such as those on a mixer, stereo pre-amp, keyboard amp, etc. Connecting the ASR-10 audio outputs to a mic-level input, such as a guitar amp or the microphone jacks on a tape deck, is not recommended, and might result in damage to the device input. Move the Volume Slider all the way up.
As with any digital musical instrument, the ASR-10 will give the best results if you keep the Volume Slider full on, and use the volume control on your mixer or amp to adjust its level. Switch the audio system on, and adjust the amplifier volume for normal listening levels. If you hear no sound while playing the keyboard, switch the audio system off and check your connections. Running Your ASR-10 Through a Home Stereo System If you are thinking about amplifying your ASR-10 through your home stereo, a word of caution is in order.
A home stereo is great for playing CD’s, albums, tapes — the dynamic range of these media is limited, and your speakers aren’t usually subjected to extreme volume changes and frequency transients. While the dynamic range of CD’s is significantly greater than LP’s or tapes, the output of a CD player is still conservative compared to the uncompressed, unlimited line- level output of a pro-level keyboard. Running your ASR-10 — or any pro-level keyboard through a home stereo at high volume levels can damage your speakers, not to mention the impedance mis-match this can create. If your only means of amplification is your home stereo, then try to keep your levels on the conservative side.
