OUTPUT PANEL The input and output jacks that cor- TIP = OUT RING = IN SUBMASTER INSERT respond to most of the functions in the 1 2 3 4 5 6 7 8 Output Panel are, logically, located in AUX SEND the jack panel directly above the Output 1 2 3 4 5 6 Panel. The 8•Bus outputs to tape (and the inputs from tape) are located on the (MONO) (MONO) (MONO) (MONO) (MONO) (MONO) L L L L L L rear panel.

See Appen- PHONES 1 2 dix A for more details on using external processing. The insert point is after the summing amplifier, but before the fader. Like the Channel Insert points, the connectors are 1/4" TRS jacks, wired unbalanced with the output or send signal on the tip, the input or return signal on the ring, and the sleeve common or ground. right return inputs and end up centered in your stereo image. When a jack is plugged into the Right input of the return, this mono feature is disabled: the left input is fed to the left return, and the right input is fed to the right return. Note: These inserts can be used as pre-fader direct outs, using an unbalanced (TS) 1/4" plug in these two ways: • Plugs are inserted just to the FIRST click. There is no interruption of the signal; OR • Plugs are inserted all the way in to the SECOND click.This interrupts the signal and routes it ONLY to the device you're sending to. Main Inserts On the upper right of the panel are two Main Insert jacks (4). These patch points allow you to insert a serial processing device, such as a compressor or an equalizer, into the Main L/R Mix. See Section 4 for more details on using external processing. The Main Insert's insert point (try saying that fast three times backward) is after the summing amplifier but before the master fader. Like the Submaster AUX Sends The six AUX Sends (2) appear as six 1/4" jacks in a row, just underneath the Sub Inserts. AUX Sends 1 and 2 are balanced TRS outputs, wired tip to high (+), ring to low (-), and sleeve to Insert points, the connectors are 1/4" TRS jacks, wired unbalanced with the output or send signal on the tip, the input or return signal on the ring, and the sleeve common or ground. Control Room Output ground. AUX Sends 1 and 2 are designed so that 1/4" unbalanced TS phone plugs can also be used, with no loss of level. AUX Sends 3 through 6 are unbalanced, with the tip high (+) and ring and sleeve tied together as ground. Nominal level is +4dBu. The two Control Room Output jacks (5) carry the signal for the Control Room speakers. They are 1/4" unbalanced, wired tip high, ring and sleeve ground. Nominal level is +4dBu. This is where you connect your control room monitor amplifier inputs. AUX Returns The AUX Returns (3) are stereo, with a L&R input for each return channel. Inputs are 1/4" unbalanced jacks, nominal level (+4dBu). One special feature: The Left input jack to each return is also labeled "MONO." If you have only one return signal, plugging it into the "MONO/L" jack only will cause it to be connected to both the left and 15
