4. Installation

Locate the unit where it will not be exposed to rain or moisture. If fluid or a foreign

object enters the unit, disconnect the power plug. Do not pull by the cord; grasp the

plug firmly. Contact an authorised dealer or service centre.

Locate the unit where it will be protected from heat and allow adequate ventilation.

Place it away from direct heat sources, such as heating vents and radiators. Make sure

the ventilation holes are not covered and air can circulate freely behind, beside, and

above the unit.

When mounting the amplifier in a rack or enclosure ensure the rear of the unit is

adequately supported. The brackets, which are supplied, fit standard 19-inch (483mm)

rack mounting systems. THE FRONT PANEL IS NOT CAPABLE OF

SUPPORTING THE UNIT ON ITS OWN.

When mounting the amplifier in a rack or enclosure ensure THERE IS ADEQUATE

VENTILATION. The cooling fans suck cool air in through the front and blow hot air

out at the rear of the unit through the ventilating grills. IF THIS AIR IS NOT

ALLOWED TO ESCAPE, OVERHEATING WILL OCCUR. Take care when

mounting other equipment in the same rack.

The B1500 and B2000 power amplifiers have been manufactured to comply with

local power supply requirements. Both have been set at a mains voltage of 240Volts.

Be sure to connect your power amplifier to a supply capable of supplying the correct

voltage and adequate current to allow full-power operation of the power amplifier.

The current demand of a power amplifier varies depending on the impedance of the

load, the output level of the power amplifier and content of the program material.

Before connecting the unit to the supply, ensure that the voltage (printed on the rear

panel of the amplifier) is correct and that a mains fuse of the correct type and rating

has been fitted in the fuse holder on the rear panel of the amplifier (The B2000 is

fitted with a circuit breaker and hence does not have a mains fuse on the rear panel).

Mains cabling to both the B1500 and the B2000 should be protected by suitable over

current device.

Note:

To convert the B1500 and B2000 to 220V operation, one should proceed as follows

(see also the following picture):

Locate the violet & brown wires from the mains transformer to the PCB spade

connectors marked up as Live Tx and Spare Tx . Connect the violet wire to Live
