19direct out 1/4"TRS jack - The input channel's signal is available at this output jack. The default signal routing is derived Pre-fader/Post-EQ. This can be changed by an internal option to Post-insert/Pre-EQ. The output jack is TRS, impedance-balanced.

20insert jack - This switching 1/4” TRS jack allows an external signal processor to be inserted into the signal path of the channel. The tip carries the SEND signal from the channel, and the ring carries the RETURN signal back to the channel. The Insert-Send point is located directly after the Lo-Cut filter on the

channel. The Return comes back into the channel at+

21line in - The Line Input is a 1/4” balanced (TRS) 10k ohm input. The tip is the positive input, which should be used for unbalanced inputs. It has less gain than the XLR input and does not have Phantom Power available. The Mic and Line inputs should not be used simultaneously.

22balanced XLR input connector - This balanced female XLR accepts a low- impedance microphone signal, or a line-level signal, depending on the position of the PAD switch on the front panel. NOTE: Pin 2 on Crest Products will always be Hot for both in and out connections.

NOTE: Directly adjacent to the stereo inputs (rear panel) there are four channels of mono inputs. On these four channels, there is a combo line/mic input jack. The line input accepts a 1/4” balanced (TRS) input or 6.3 mm plug.

In situations where the	+
preamp circuitry is not
needed, the Insert Return

can be used as the channel’s input, such as when using an expensive, outboard tube mic preamp, for example.

In these cases, the Tip contact of the plug should not be connected. The signal from the external pre- amp should feed the Ring contact (the Sleeve contact is the ground return).
