560A
current settings are indeed enhancing the signal in a desirable way. This is done by matching the levels while switching
in and out of bypass mode. Up to 20dB of gain can be applied using this control. The OUTPUT GAIN control does not
interact with the threshold of compression/limiting.
5. BYPASS Button & LED
Engage the BYPASS button to bypass the 560A processor. The BYPASS LED will light when the processor is bypassed.
The 560A is designed with a hardwire bypass – meaning when bypassed, the signal passes straight from the input jack
directly to the output jack, without going through any of the 560A’s circuitry. Bypass mode is especially useful for making
comparisons between the processed and unprocessed signals.
6. THRESHOLD LEDs
These three LEDs indicate the relationship of the input signal level to the threshold of compression. The green ”BELOW”
LED lights when the signal level is below the set threshold. The red “ABOVE” LED lights when the signal level is
above the set threshold. When the OVEREASY button is engaged, the yellow LED lights when the signal level is in the
OverEasy region, which is in the range just below the set threshold (see
‘Compression Graphs’ on page 6
to see a
plot showing the OverEasy region).
7. INPUT/OUTPUT LEVEL Meter
This LED meter shows input or output signal level, as selected with the LEVEL button. When the LEVEL button is
engaged, the INPUT LED will light and this meter will show input signal level. When the LEVEL button is disengaged,
the OUTPUT LED will light and this meter will show output signal level. The output meter is post the OUTPUT GAIN
control. The “0” indicator on this meter is equivalent to +4dBu (1.23VRMS).
8. GAIN REDUCTION Meter
This LED meter shows the amount of gain reduction applied by compression or limiting and can display up to 40dB of
gain reduction (although the 560A is actually capable of delivering up to 60dB of gain reduction).
9. LEVEL Button & INPUT/OUTPUT LEDs
Engage this button to display input signal level on the LEVEL meter (the INPUT LED will light). Disengage this button to
display output signal level on the LEVEL meter (the OUTPUT LED will light).
