Calibrating the system

In Calibration you can make adjustments using a number of
different signals, shown in the table below. Normally the 565
selects the most appropriate signal for the test.
Signal
Description
High
Continuous ‘pink’ noise, band-limited
500Hz–2kHz.
Low
Continuous ‘pink’ noise, band-limited
20Hz–80Hz.
Digital In
Any signal applied to the appropriate
Optical In
input is combined to mono (L+R) and
Analogue In
then used to supply outputs under
calibration. This allows adjustments to
be made using speech or music, or
external test signals from CD or
LaserDisc.
Sine Sweep
For checking room resonance and
vibration; see opposite.
Silence
No test signal – useful for tracking
down hum and noise.
