Installation

Connecting Input

Both inputs are balanced. If a balanced output is unavailable, you can also use a unbalanced one,
connect pin 3 – with pin1 mass (see below). Unbalanced line may result in noise over long cable runs.

1= earth / mass, 2=signal +, 3=signal –

Connecting Output

Make sure the amplifier is turned off before you wire the system. Speakers can be connected using
speaker NL4 plugs or bare wire for your binding post output connectors. Using the guidelines below
select the appropriate size of wire bases on the disctance between the amplifier and speaker.
Distance Wire Size
<10m 1.5mm2
>10m <20m 2.5mm2
>20m <30m 4.0mm2

NOTE: Never connect a hot (+) output to ground or (-) output and never connect the hot (+) to
other hot outputs!

Connect to mains power

Before plugging the unit in always make sure that the power supply matches the product specification
voltage. First connect the IEC end of the cordset to the IEC connector on the amplifier then plug the
other end of the cordset to the AC mains.

Please read instructions below for reliable and problem free use:

Be sure all connections made are made in the correct way.

•

• Check if the connected speakers are compatible with the amplifier.

• Ensure there is adequate ventilation.

• Prevent exposure to moisture.

• Never plug speakers in/or out while in use, this can result in serious damage.
