Detailed instructions for use are in the User's Guide.
[. . . ] Do not open the case or attempt repairs or modifications yourself This product contains no user-serviceable parts. Opening the case and/or tampering with the internal circuitry voids the warranty. Always power off before making connections Always turn the power OFF before connecting or disconnecting cables. This is important to prevent damage to the unit itself as well as other connected equipment. [. . . ] Use the paired INPUT 13/14 and 15/16 jacks (see page 17, rear panel 5) to input stereo signals. If you connect signals only to the 13L (MONO) jack or 15L (MONO) jack, the same signal will be sent t the o M14 and ST buses.

These controls are used to route the pre fader signals from the stereo input channel to MIX buses 14. When stereo signals are input, the L channel signal will be sent to MIX buses 1, 3, and the R channel signal will be sent to MIX buses 2 and 4. Note: When you press down the M1M4 switches to the FIX position in the Variable/ Fix select section (see page 6), the output level of signals sent to the MIX buses will be fixed and the corresponding M1M4 mix level controls will be disabled.

I PRE (Pre-fader) switches
These switches are used to select pre- or post-fader for signals sent from the stereo input channel to MIX buses 510. When you turn these switches on, the pre-fader signals are sent to the corresponding MIX bus pair.
J BAL (Balance) control
This control is used to adjust the left and right balance of signals sent from the stereo input channel to the ST bus.
K ST (Stereo) switch
When you turn this switch on, the stereo input channel signals will be sent to the ST bus. Signals that pass through the M1M4 mix level controls of each input channel (see page 2, monaural input channel 8, and page 4, stereo input channel 6) are sent to the corresponding MIX buses.

Mix section
This section consists of the output channels that handle MIX bus 110 signals individually. Signals that pass these output channels are output from MIX OUT 110 jacks (see page 17, rear panel 6), and also routed to the AFL bus. The signal is not sent to the AFL bus, either.

You will monitor PFL signals (signals routed from input channels/AUX returns to the PFL bus) or AFL signals (signals routed from MIX buses 110/ST buses/MATRIX 12 to the AFL bus). If any one of the PFL switches for the input channels/AUX returns is turned on, the PFL indicator 2 will light up. In this case, the PFL bus signals (not the AFL bus signals) are routed to the C-R MONITOR OUT jacks and PHONES jack. If all the PFL switches are turned off, the AFL bus signals are sent to the C-R MONITOR OUT jacks and PHONES jack. Note: If you turn on any one of the PFL switches for the input channels/AUX returns while monitoring the AFL bus signal, the switching circuit will switch the signal to the PFL bus signal.

You can monitor the signals input from the TAPE IN jacks (see page 18, rear panel N).

This indicator lights up when any one of the PFL switches for the input channels/AUX returns is turned on, indicating that the PFL bus signal is currently being monitored.
