7:Mic inputs (channels 1 and 3) - Use these electronically balanced XLR jacks to connect a microphone to channel 1 and/or channel 3. These are intended to accept signal from
8:Trim control (black) - This knob determines the input level of the mic signal connected to channel 1 and/or channel 3. Continuously adjustable from +4 dB to
9:Line inputs - Use these electronically balanced 1/4" jacks to connect line- level sources such as synthesizers, drum machines, CD players, tape decks, or effects processors to any of the PL 2404’s
PL 2404” section on page 10 provides more information on how best to use channel inputs. WARNING: Do not connect the channel 1 or 3 line input if you already have something connected to that channel’s microphone input (see #7 above); these channels are designed to accept only one source or the other.
10:Channel Inserts (1 - 4) - Use these to insert an external effects processor (such as outboard equalizer, compressor/limiter or noise gate) into any of the PL 2404’s channels 1 - 4 in an “effects loop” configuration. These jacks accept 1/4" TRS plugs, with the ring carrying the send signal and the tip carrying the return signal. Normally, this will be connected to a
11:Bus Inserts (1 - 4) - Connect the output from another device to these in
order to “submix” in their signal to the PL 2404 at unity gain. This can be used to link multiple PL 2404s or to add the output from another mixer to the PL 2404 without taking up channel line inputs. The Bus Insert jacks accept unbalanced 1/4" plugs. See the “Linking the PL 2404” Application on page 26 for more information.
12:Aux Returns (1 - 4) - These unbalanced 1/4" inputs allow you to route
signal from external devices such as effects processors to any of the four stereo Aux Returns. These jacks accept 1/4" TRS plugs, with the tip carrying the left signal and the ring carrying the right signal (sleeve is common ground). See the “Using Aux Sends and Returns” section on page 20 for more information.
13:Aux Sends (1 - 4) - These unbalanced 1/4" outputs allow you to route signal from any of the four discrete Aux Sends to external devices such as effects processors. All four PL 2404 Aux sends are
