INPUT CHANNEL SECTION

The following section details each part of the PA324’s INPUT CHANNELS including the 3-BAND EQ, the MONITOR and EXF sends, PAD and LEVEL controls.

1Channel Equalizer (HIGH MID LOW)

The PA324 input channels feature a 3-band equalizer allowing you to adjust the high, mid, and low frequencies independently on each chan- nel. The channel’s frequency response is flat when the knobs are in the "12:00" position. Rotating the knob towards the right will boost the corre- sponding frequency band by 15dB, and rotating it towards the left will cut the frequency by 15dB. The frequency centers, range of boost or cut, and equalizer type for each band are as follows:

High: 12KHz +/- 15dB shelving type

Mid: 2.5KHz +/- 15dB peaking type

Low: 80Hz +/- 15dB shelving type

Each of the PA324’s channels include a MONITOR send which controls the amount of that channel’s signal that is sent to the MONITOR bus. The Input channel’s MONITOR sends are mixed together and are sent to the speakers connected to the POWER AMP 2 A/B jacks if the POWER AMP select switch is set to MAIN+MONITOR.

3Effects Send (EFX)

The PA324 provides high quality, 24 Bit digital effects, and the level of effects can be set independently on each channel. The channel’s EFX (Effects) knob controls the amount of signal that is sent to the EFX bus. The signal of the EFX bus is routed to the DSP EFX section for onboard signal processing. The EFX sig- nal can also be sent to an external effect device connected to the EFX OUT jacks located on the front panel.

NOTE: The channel’s EFX signal is sent to the EFX bus from a location in the signal path after the LEVEL control (4). This is commonly referred as a POST FADER send. This means that the amount of signal that is sent to the EFFECT bus will be affected not only by the setting of the EFX knob control, but it will also be affected by the setting of the LEVEL control.

4Level Control (LEVEL)

The LEVEL control adjusts the output volume of each channel.

5Pad Switch (PAD)

The PAD switch attenuates the input signal by 30dB. When connecting a hot signal such as a line level device to channels 1-6, or if the mic input is distorted, turn this switch on (the pressed-in position) and readjust the LEVEL control.
