XLogic E Signature™ Channel Owner’s Manual

Meter Calibration

Equipment Required:		Calibrated audio oscillator and audio level meter
Test Signal:		1kHz sinewave @ +24dBu
Input and Output:		Oscillator to Line Input and Output to the audio level meter
Unit Setup:	1.	Set both Line Gain and Output Gain to indent (0dB).
	2.	Check for +24dBu output level.
Adjustment:	1.	Adjust VR24 until the ‘+24’ meter LED is just illuminated.
	2.	Reduce oscillator level to +18dBu, then +12dBu etc. and check that the correct
		meter LEDs light. At each point, reduce the level slightly using the Output Gain
		control and check each LED extinguishes.

EQ Alignments

Equipment Required:		Calibrated audio oscillator and audio level meter
Test Signal:		Sinewave @ 0dBu, frequencies as specified below
Input and Output:		Oscillator to Line Input and Output to the audio level meter
Unit Setup:	1.	Set both Line Gain and Output Gain to indent (0dB). Check that the Filters and
		Dynamics are switched out.
	2.	Switch the EQ in and release all other EQ switches.
	3.	Set all of the Q and Frequency controls fully anti-clockwise and all EQ gain
		controls to their centre indent.
LF EQ – Maximum Gain
Adjustment:	1.	Ensure that the BLK switch is released.
	2.	Set LF Gain to maximum and select LF BELL. Set the audio oscillator for 80Hz
		and adjust LF Frequency to find the maximum level on the audio level meter.
	3.	Adjust VR4 for +15dBu ±0.25dB.
	4.	Switch BLK in and re-adjust LF Frequency for maximum level.
	5.	Adjust VR6 for +18dBu ±0.25dB.
	6.	Reset LF Gain to its centre indent position, release the BLK switch and de-select
		LF BELL. Re-check the audio level meter for 0dBu.

LMF EQ – Maximum Gain

Adjustment:	1.	Ensure that the BLK switch is released.
	2.	Set LMF Gain to maximum and LMF Q fully anti-clockwise. Set the audio
		oscillator for 1kHz and adjust LMF Frequency to find the maximum level on the
		audio level meter.
	3.	Adjust VR9 for +15dBu ±0.25dB.
	4.	Switch BLK in and re-adjust LMF Frequency for maximum level.
	5.	Adjust VR12 for +18dBu ±0.25dB.
	6.	Reset LMF Gain to its centre indent position and release the BLK switch. Re-
		check the audio level meter for 0dBu.

HMF EQ – Maximum Gain

Adjustment:	1.	Ensure that the BLK switch is released.
	2.	Set HMF Gain to maximum and HMF Q fully anti-clockwise. Set the audio
		oscillator for 3kHz and adjust HMF Frequency to find the maximum level on the
		audio level meter.
	3.	Adjust VR14 for +15dBu ±0.25dB.
