[. . . ] Dynamic and ribbon mics don't require phantom power and are unaffected when the power is on. These high-quality mic inputs also feature up to 50dB of preamp gain that you can adjust with the Gain knob. Another useful feature of these mic inputs is a high-pass filter (HPF) that can be turned on and off with the HPF switch. When you activate this switch, all frequencies below 75Hz are cut from the signal. This is useful for mic or line signals that don't have much bottom end, such as vocals, snares, cymbals and electric guitar. You'll want to leave this inactivated for instruments like basses and kick drums. Although chances are your microphones will work fine with these mic inputs, we recommend that you do some checking up on the type of microphone you're using, especially if it's one of the older vintage models. Verify that your microphone requires phantom power and make sure its output is low impedance, balanced and floating. Line Inputs (Channels 1 ­ 4) The line inputs, marked LINE IN, are balanced 1/4" jacks that offer the same 50dB of preamp gain and the high-pass filter provided by the mic inputs (however, phantom power does not apply to line inputs). These inputs accept line-level instruments such as keyboards and drum machines. If you find that your instrument has a weak line signal, just plug it into channels 1 ­ 4 and crank it up with the Gain knob. Always connect your microphones before activating phantom power. Microphones tend to be very sensitive, and the sudden power surge can do permanent damage to the mic's circuitry. It's also a good idea to lower mixer levels before you activate phantom power. 21 2 A Tour of the MultiMix Line Inputs (Channels 5 ­ 12) Unlike channels 1 ­ 4, the line inputs on channels 5 ­ 12 are stereo inputs that have left and right inputs. If you're using one of these channels as a mono input, plug your instrument into the left input. Channels 5 ­ 12 don't have the extra gain found on channels 1 ­ 4 because most line-level instruments don't require the extra boost. Synthesizers and other electronic instruments will work especially well on these channels. These inputs are also good for connecting CD players or tape decks, as these audio sources don't require extra gain. Digital Output Jack (Multimix-12FXD and Multimix-16FXD only) The digital output jack is used to send the 44. 1 kHz stereo audio signal to an Alesis Masterlink or any other recording device such as a DAT recorder or a PC with an S/PDIF enabled sound card installed. Always use a high quality cable when connecting the DIGITAL OUTPUT JACK to your recording device. We recommend that you use a cable that is specifically designed to carry a digital signal and does not exceed 5 meters (16. 4 ft) in length. Any audio signal that is routed to the MAIN OUTPUTS will also be sent out of the DIGITAL OUTPUT jack. The level is controlled by the MAIN FADERS. The DIGITAL OUTPUT mirrors the output from the MAIN OUTPUTS. PHONE Jack The headphone jack accepts 1/4" jacks. If your headphones are 1/8", you can find a 1/8" to 1/4" adapter in most electronics stores. AUX RETURNS These are the 1/4" jacks where you connect the outputs of an external effects processor or other audio source. Each aux return gives you 15dB of gain that can be controlled by the AUX RET A and EFFECTS / AUX RET B LEVEL knobs in the mixer's output section. If you are using an effects device with only a mono output, plug it into the left return of STEREO AUX RETURN. It will appear in the center of the stereo spectrum, and not to the left. AUX SENDS And this is the 1/4" jack where you connect the line that's going into the input of an external effects processor.
