MAIN SECTION

The PA 324 has two internal power amplifiers and depending on the POWER AMP selection switch, the amplifiers are sent the MAIN or MONITOR bus sig- nal. The following section describes the MAIN bus operation, which allows you to adjust the over-all tone and volume, and specify the mix level of the built-in effects.

	The PA324’s 7-band Graphic Equalizer allows
	you to contour the frequency response of the
	MAIN mix bus signal, providing a maximum of
	+/-12dB of cut/boost for each frequency band.
	This is an especially useful tool for cutting fre-			1	1
	quencies that cause annoying feedback. The
	frequency response is flat when a slider are in			2	2
	the center position. Moving a slider in the posi-
	tive direction will boost that frequency by as		AUX IN	TAPE IN	REC OUT	MAIN OUT	MONITOR OUT
	much as 12dB, and moving the slider in the
	negative direction will cut that frequency by up
	to 12dB. Once you set a response curve using the Graphic Equalizer, the EQ curve is applied to both the
	MAIN bus signal that is output to the speakers, and the line level signal which is output from the MAIN OUT
	jack.

16Effects Return Control (EFX RETURN)

The EFX RETURN control is used to adjust the level of the effect sound being sent back from the built-in digital effect to the MAIN mix bus. This allows you to hear the DSP effects in your monitor speakers.

17Volume Control (MASTER)

The MASTER MAIN level control is the over-all volume control for the MAIN bus. The MAIN level affects both the MAIN bus signal which is output to the speakers and the line level signal which is output from the MAIN OUT jack.

18Output Level Meter

The OUTPUT LEVEL METER allows you to monitor the level of the signal which is being sent to the MAIN OUT jack (input/output panel 5).

NOTE: To avoid distortion, adjust the MASTER LEVEL control so that the 0 indicator LED lights occasionally.
