See page 6 for settings and a list of RS232 commands. 5. Channel Select: Selects one of the 8 input channels to allow level, EQ and matrix adjustment. 6. Input Level Indicator: Shows if input signal is present. To set for optimum working level, normal signal should be kept under 0dB. 7. Bass: Adjust the Bass level on the associated channel. Increasing Bass may make music sound fuller, reducing the Bass in reverberant spaces may improve speech intelligibility. 8. Treble: Adjust the treble on the associated channel. Increasing the treble may improve intelligibility, decreasing the treble may reduce the onset of high frequency feedback. 9. Channel Volume Indicator: Shows post fader level of the selected channel. 10. Channel Volume: Adjusts level of the selected channel. 11. Zone Matrix: Press to enable/disable channel routing to the associated output zone. Blue light indicates routing is that zone is active. 12.
