Operation
Numbers in this chapter refer to the
controls and connections diagram on
page 17.
Starting up
Once the external cables are connected to
the units, ensure the Master On/Off switch
(12) is in the Off position, and then operate the
system as follows:
o
Plug the mains cable into a mains socket
outlet.
o
Turn on the mains socket outlet switch.
o
Switch the Master On/Off switch on the
rear panel, to ON (12).
After a brief initialization sequence, as
displayed on the front panel LEDs, the power
LED (2) will glow red, which indicates the unit
is in Standby mode. In this mode a small
current is drawn from the mains supply, but
the unit cannot drive the loudspeakers.
o
Press the Standby/On mode button (1)
once to switch between Standby and On
modes.
In ON mode, the LEDs (3) on the front panel
glow blue to show the unit is active. (When
switching from Standby to On, some amplifier
module LEDs may briefly flash red before
operating a steady blue. This is normal
operation.)
The multi-channel power amplifier is now
ready to drive your loudspeakers.
If the multi-channel power amplifier trigger
(6) is connected to a con rol center such
t
as the Halcro Logic SSP, it can be left in
Standby mode since the con rol cen er will
t
t
operate the amplifier when required.
Shutting down
It is safer to turn the mains power off when not
using the multi channel power amplifier for
extended periods. However the MC unit may
be left in Standby mode for periods between
active use. Select the Standby/On button to
toggle between Standby and On.
To turn the unit off, switch the master On/Off
switch (12), and then switch off and/or
disconnect from the mains at the socket
outlet.
The multi-channel power amplifier has a very
short warm up period when turned on again.
If the unit is connected via the
trigger input (6) to a control
center (SSP the unit cannot
be switched to Standby mode
using the Standby/On button
),
