EQ Alignments
Equipment Required: Calibrated audio oscillator and audio level meter
Test Signal: Sinewave @ -6dBu, frequencies as specified below
Input and Output: Oscillator to Input A (or B) and Output to the audio level meter
Unit Setup: 1. Set the Input Gain to +6dB and the output gain to the indent. Press HI-Z switch
IN. 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.
Gain at Indent
Adjustment 1. Measure the audio level with a probe. On the upper card (629603), measure the
following test points and adjust as required:
a. Probe TP1 and adjust VR22 for a minimum.
b. Probe TP2 and adjust VR23 for a minimum.
c. Probe TP3 and adjust VR25 for a minimum.
d. Probe TP4 and adjust VR28 for a minimum.
e. Probe TP5 and adjust VR27 for a minimum.
2. Check the audio level meter for 0dBu ±0.01dB (adjust the audio oscillator if
necessary).
HF EQ - Maximum Gain
Adjustment: 1. Set HF Gain to maximum and select HF BELL. Set the audio oscillator for 12kHz
and adjust HF Frequency to find the maximum level on the audio level meter.
2. On the 629603 (upper) card adjust VR26 for +20dBu ±0.25dB.
3. Reset HF Gain to its centre indent position, de-select HF BELL and re-check the
audio level meter for 0dBu.
HMF EQ - Maximum Gain
Adjustment: 1. 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.
2. Adjust VR30 on the 629602 card for +21dBu ±0.25dB.
3. Reset HMF Gain to its centre indent position, re-check the audio level meter for
0dBu.
LMF EQ - Maximum Gain
Adjustment: 1. 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.
2. Adjust VR29 on the 629602 card for +21dBu ±0.25dB.
3. Reset LMF Gain to its centre indent position, re-check the audio level meter for
0dBu.
LF EQ - Maximum Gain
Adjustment: 1. 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.
2. On the 629603 (upper) card adjust VR24 for +16.5dBu ±0.25dB.
3. Reset LF Gain to its centre indent position, de-select LF BELL and re-check the
audio level meter for 0dBu.
