OPERATION

IMPORTANT: All signal source equipment should be adequately

earthed. This not only ensures your safety but everybody else's as well.

Faults can and do occur in mains connected equipment where the

chassis can become "live" if it is not properly earthed. In these instances,

the fault in a "floating" (ungrounded) piece of equipment will look for the

shortest path to ground, which could possibly be your ampliﬁer's input.

If the fault current is large enough, it will destroy the input to your

ampliﬁer and look for the next available path, which may be you!

Before making any connections to your AMP Series ampliﬁer, observe the

following:

Ensure the mains voltage supply matches the label on the rear panel of your

•

ampliﬁer (+/- 10%).

Ensure that the power switch is OFF.

•

Ensure that all system grounds (earth) are connected from a common point.

•

Avoid powering equipment within a system from multiple power sources that

may be separated by large distances.

Check the continuity of all interconnecting leads to your ampliﬁer; ensure

•

that there are no open or short circuited conductors.

Ensure that the power handling of your load (speakers) can adequately cope

•

with the power output of the ampliﬁer.

Before operating your AMP Series ampliﬁer, ensure that:

The BRIDGE Switch is not engaged if you are not running the amp in

•

bridged mode.

Powering Up

REMEMBER: The ampliﬁer should be the last piece of equipment

that you turn on and the ﬁrst piece of equipment that you turn off.

We recommend turning the attenuators on your ampliﬁer down when

turning the unit on.

Sensitivity

Your ampliﬁer is a linear device operating with a ﬁxed input to output voltage

gain (less attenuation). The maximum output voltage swing is determined by the

applied mains voltage, load, load type and the duty cycle of the applied signal.

The input sensitivity for your AMP Series ampliﬁer when the level control is at

maximum position (fully clockwise) and the VCA is disabled is nominally:

+2.2dBu (1.00 volts in) for rated power into a 4 Ohm load.

Each channel of your AMP Series ampliﬁer has a nominal balanced input

impedance of 30kOhms (@1kHz) and should not present a difﬁcult load for any

signal source.

Your signal source (i.e. the equipment feeding signal to the ampliﬁer) should

have an output impedance of 600 Ohms or lower to avoid unwanted high

frequency loss in the cabling.
