Customising the Control Unit
28
The 501/501V Control Unit allows you to program the level of
each source independently, to suit your other equipment, so that
when you switch between sources the volume stays the same.
When you are programming levels the control unit operates as a
preamplifier with a fixed volume setting equivalent to 65. This
level is chosen to be comfortably loud on average sources. You
can switch between sources and adjust the relevant input levels
to achieve the setting you want.
You can increase the sensitivity of any source by up to 15 steps
of 1dB. The loudest source, usually CD, should therefore be
chosen as the reference.
