Equaliser

This is a four band equaliser that can be switched between two different sets of curves; one based on SSL’s ‘02’ (‘Brown Knob’) EQ and the other based on the latest version of the classic ‘242’ E Series (‘Black Knob’) EQ. High and low pass filters are also available.

HF Band controls:
Frequency	Variable from 1.5kHz to 16kHz
Gain	Variable between ±15dB (‘02’)
	Variable between ±18dB (‘242’)
‘Q’ (on ‘BELL’ setting)	0.8 (‘02’)
	1.3 (‘242’)
HMF Band controls:
Frequency	Variable from 600Hz to 7kHz
Gain	Variable between ±15dB (‘02’)
	Variable between ±18dB (‘242’)
‘Q’	Variable from 0.5 to 2.5 (‘02’)
	Variable from 0.5 to 4 (‘242’)
LMF Band controls:
Frequency	Variable from 200Hz to 2.5kHz
Gain	Variable between ±15dB (‘02’)
	Variable between ±18dB (‘242’)
‘Q’	Variable from 0.5 to 2.5 (‘02’)
	Variable from 0.5 to 4 (‘242’)
LF Band controls:
Frequency	Variable from 30Hz to 450Hz
Gain	Variable between ±15dB (‘02’)
	Variable between ±18dB (‘242’)
‘Q’ (on ‘BELL’ setting)	0.8 (‘02’)
	1.3 (‘242’)
Filter controls:
Low Pass Frequency	3kHz to 16kHz (–3dB Point)
Low Pass Slope	12dB/octave
High Pass Frequency	20Hz to 350Hz (–3dB Point)
High Pass Slope	12dB/octave (‘02’)
	18dB/octave (’242’)

Measurement Conditions

Signal applied to Line Input and measured at Output. EQ switched In. All EQ controls set centre as appropriate.

THD + N	< 0.05% at +20dBu 1kHz
Frequency Response	±0.25dB from 20Hz to 20kHz
Output Headroom	> +26dBu at onset of clipping
Noise	< –73dBu
