You should read the following useful notes carefully before you begin to install and use the
equipment.
There are no user adjustable parts inside the equipment. You should refer to a qualified
engineer or return the equipment to either the dealer or the Audiolab distributor for any
servicing requirements.
Important notice: Please do not connect loudspeakers or source components to the amplifier
when switched on. Always switch 8300MB off before making connections!
The Audiolab 8300MB mono amplifier will be warm when running, the actual temperature
depending on the power output. A resettable current trip will automatically switch the
amplifier off under gross overload or short circuit output etc. The fins of the heat sink should
be kept clear of obstruction to allow adequate ventilation in normal use.
Connecting to the AC power supply
The Audiolab 8300MB mono amplifier is supplied in four versions suitable for connection to
240V, 230V, 115V or 100V AC power supplies. Before connecting the amplifier check that
you have the correct version. If the amplifier is connected to a lower voltage than marked,
the maximum output power will be lower than specified.
Please check with the dealer if you have any doubt as to the voltage in your area or intend to
use the equipment in regions which use different mains voltages.
The Audiolab 8300MB mono amplifier is provided with a mains cable fitted with an
appropriate mains plug. This plug should not be cut from the cable. If for any reason, the
plug is removed it must be safely disposed. It must never be plugged into a mains outlet.
Any replacement plug should be wired to the supplied mains cable as follows:
The BROWN wire must be taken to the LIVE terminal
The BLUE wire must be taken to the NEUTRAL terminal

Signal Input Connections

Balanced XLR Connections: If you are connecting a Audiolab 8300MB mono power
amplifier to the Audiolab 8300CD CD player, we strongly advocate the use of the balanced
XLR connections. XLR inputs use 3 conductors, one for ground and two for the voltage plus
and minus signals. In this way the signal transmitted to the amplifier is thus 'cleaner' and free
from earth-induced currents and other air-borne interference.
XLR interconnects should be of screened, twisted pair construction. Refer to your dealer if in
doubt.
Unbalanced Connections: If you cannot use the XLR inputs, connect an RCA phono
interconnect between the unbalanced inputs on the 8300MB rear panel with the matching
output of the source unit.
Input Selector: When connecting the signal input, ensure the Input Selector is switched to
the appropriate input.
• In the normal (extended) position the balanced XLR input is selected.
• Press the selector in for unbalanced RCA phono input.

Trigger Connections

Audiolab 8300MB mono amplifier has one pair trigger connections at the real panel, can
be activated by 8300CD's or any other source's trigger output. 8300MB can also bypass the
source's trigger signal to another 8300MB, then one source can trigger two 8300MB . If you
have a 8300 system, we advise connecting the triggers. This will enable all 8300 units to be
brought in and out of standby along with the trigger connections.
To connect to your control unit, you will need a cable with one end to match the trigger
output of the control unit and other terminating in a 3.5mm jack plug. For Audiolab 8300
series units, this will be a 3.5mm to 3.5mm interconnect.
Connect the either of the trigger of Audiolab 8300MB to the TRIG OUT of 8300CD or any
other control unit having a 12V master trigger out, and then connect the output trigger of
8300MB to another 8300MB's trigger.
