Front Panel Controls
The following pages describe the functions of each control or jack on the front
and rear panels of the SA330x. Refer to these numbered diagrams for each
numbered control on the following pages.
1. Mute – The Mute switch silences the signals from Channels 1 and 2 to the
speakers and all the XLR outputs. It also mutes audio input from an audio
device connected at the Accessory port. The mute does not affect the Aux
inputs or Monitor input.
2. Master Volume – Set the overall level of the SA330x here.
Note: Controls 3 through 13 are identical for both channels.
3. 12dB Pad & Clip LED – When you have a high output source and the
Clip LED (located in the center of the Pad button) comes on at low Gain
settings, push this switch to adjust your source level into a more useable
range.
4. Gain – Use the Gain knob to set the level of the signal.
5. Phase – Use the Phase switch to improve low frequency response at low
volumes or reduce microphone or instrument feedback at high volumes.
6. High – Boost highs to add “air” and presence to your sound. With the knob
set at 12 o’clock, the control is effectively out of the circuit.
7. Anti-Feedback – If you encounter low-frequency feedback, sweep this
notch filter control to isolate and eliminate the resonance. To learn more
about acoustic feedback, see page 12.
8. Mid – This control affects how well your source signal blends in or stands
out in the mix. Slightly boosting the Middle control is useful for ensuring
that vocals or speech are clear and intelligible. At loud volumes a midrange
cut will achieve a more natural sound. With the knob set at 12 o’clock, the
control is effectively out of the circuit.
9. Reverb Level – Controls the amount of digital reverb in the channel.
10. Low – Boost here to add weight to the sound. In general, boost bass at
low volumes, and flatten it out (or cut) at higher levels. With the knob set
at 12 o’clock, the control is effectively out of the circuit.
