The load capacity of the loudspeakers connected to the device must be
appropriate to the amplifier. The speaker impedance must be at least 4 Ohm
(DIN). Always connect your loudspeakers using ready-made, purpose-designed
speaker cables terminating in approved connectors. The speaker cables and
connectors must be insulated in accordance with regulations, and the conductors
must have a minimum cross-sectional area of 2.5 mm².
The output stages are designed to cope with a minimum load of 2
, but conti-
nuous operation at very high volume produces high currents in the power output
stages which can lead to overheating. This in turn trips the protective circuit
which switches the amplifier off automatically.
POWER LINK IN
Socket for connecting the optional supplementary mains power supply
PS 3000 HV
.
Since the contacts of the POWER LINK socket carry high voltages and
currents, for safety and to prevent staining the terminal contacts, the screw cap
should left in place so long as no
PS 3000 HV
is connected. The connection
between the two devices must only be made using the
Power Link cable
supplied with the
PS 3000 HV
.
TRIGGER
The
A 3000 HV
can be turned on and off by means of a switching voltage (+5
… +20 Volt) connected to this socket.
Connector assignment (3.5 mm barrel plug)
LAN
Interface for diagnosis work and computer-controlled operation of device
functions. (Home-Automations-Systems e. g. CRESTRON, AMX).
H
LINK
Control input for
devices with
H
LINK
output.
RC IN
If you wish to control the machine with a remote control handset, then the
accessories
E2000
remote control receiver can be connected to this
socket.
Mains input
This socket is for mains connection.
For correct connection refer to the sections
'INSTALLATION AND WIRING'
and
'SAFETY NOTES'
.
Back panel controls
AMP MODE
This switch is used to select the '
Stereo
' or
'High Current Mono
' operating
mode.
The operation mode will be changed only, if the device is powered off and
on again
(Please wait 30 seconds until the device is powered on again).
Please refer to the wiring diagram (see Appendix A) for the correct method of
connecting the
A 3000 HV
in
Stereo a
nd
High Current Mono
mode.
INPUT SELECT
This switch selects the type of connection in use. Set the switch to
Balanced
if
you wish to use the symmetrical XLR sockets, or
Unbalanced
if using the Cinch
(asymmetrical) connections.
