MIXPAD 4 Channels
1:Mic inputs - Provided in monophonic channels only (channels 1 and 2). Use these electronically balanced XLR jacks to connect microphones to either of the MIXPAD 4’s two monophonic channels. These are intended to accept signal from low-level, low-impedance mics but can also be used for signal from other sources (such as direct injection boxes) if the channel’s Trim control is turned down (see #2 below). When the channel’s Phantom Power switch is pressed in (see #2 on page 16), 18 volts of phantom power is delivered to pins 2 and 3 of that channel’s XLR mic input, enabling you to connect most condenser microphones. WARNING: Do not connect a channel’s microphone input if you already have something connected to its line input; each channel is designed to accept only one source or the other.
2:Trim - Provided in monophonic channels only (channels 1 and 2). This knob determines the input level of the connected mic or line signal. Continuously adjustable from -6 dB to -50 dB, the input trim is at unity gain (no boost or cut) when set to the “0” (9 o’clock) position. The input signal is boosted when the trim is turned to the right of “0” and attenuated when turned to the left of “0.” For information on how to properly set this for each channel, see the section on page 23 in this manual entitled “Setting The Correct Gain Structure.”
3:Line inputs - Use these 1/4" jacks to connect line-level sources such as synthesizers, drum machines, CD players, tape decks, or effects processors to any of the MIXPAD’s mono or stereo channels. The line input jacks for monophonic channels (channels 1 - 2) are electronically balanced, so you should use balanced three-conductor cabling and Tip/Ring/Sleeve (TRS) plugs wherever possible (unbalanced two- conductor plugs can also be inserted into these inputs, but you’ll get better signal quality and less outside noise and hum if you use balanced lines). WARNING: Do not connect a channel’s line input if you already have something connected to its microphone input; each channel is designed to accept only one source or the other.
The line input jack for the stereo channel (channels 3 - 4) accepts a single unbalanced 1/4" TRS plug, with the tip carrying the left signal and the ring carrying the right signal (sleeve is common ground). See the “Connecting The MIXPAD” section on page 19 in this manual for additional information on how best to use channel inputs.
