Three Null LEDs that illuminate if the position of the ‘Q’, ‘Boost/Cut’ or ‘Frequency’
potentiometers in the HF EQ section are in a position different from that pro-
grammed.
Upper LED
“dB”
Null LED for ‘Boost/Cut’ pot
Middle LED
“Q”
Null LED for ‘Q’ pot
Lower LED
“Hz”
Null LED for ‘Frequency’ pot
To recall the programmed position, rotate the appropriate potentiometer until the
LED goes ‘out’.

The ‘Q’ control varies the bandwidth of the EQ section in the range Q=1 to Q=3. A
low value of Q gives a wide bandwidth. This means that a relatively large range of
frequencies (either side of the centre frequency selected by the ‘Frequency’ control)
have boost/cut applied.
As the value of Q is increased, the bandwidth is reduced, so that a very much
smaller range of frequencies have boost/cut applied. The position of the ‘Q’ potenti-
ometer is recorded during a SAVE command.
