2 - Introduction
The AMP150.1H, AMP300.1H and AMP500.1H are compact, powerful high-voltage Class D amplifiers. They
deliver 150W, 300W and 500W respectively on a 70V or 100V line.
They feature volume control and LED indicators (signal, clip and protection). Input and output connections are
equipped with Euroblock connectors.

1
Power switch
Switches the amplifier on and off.
When the amplifier is on, the VOL potentiometer LED
is lit.
2
Volume control knob
This potentiometer adjusts the input signal level.

Indicator LEDs
These LEDs give an indication of the amplifier's status:
- SIGNAL : Indicates that a signal is present at the power
stage input.
- CLIP : Indicates that the current signal level is too high.
- PROTECT : Indicates that the amplifier is in protection
mode due to overheating or short-circuit.
Notes:
-It is normal for the PROTECT LED to light up for a few
seconds when the amplifier is switched on.
-If the PROTECT LED remains lit, switch off the
amplifier, wait for it to cool down and check the wiring.
-If on power-up it remains lit even though the amplifier
is not warm and all the wiring is correct, consult a
specialist technician.

INPUT / LINK
Connect line-level signals to the INPUT input.
Input signals can be either balanced or unbalanced.
The LINK terminal allows the input signal to be re-
injected into another amplifier.

Output voltage selector switch
This selector allows you to choose the output voltage
between 70 V and 100 V. Only the right-hand dipswitch is
active, the left-hand one is not connected (NC).
6
Output terminals
Connect your speakers to these terminals. The two
terminals are wired in parallel.
Dangerous voltage
Loudspeaker lines should be connected to
the amplifier last.
Switch on the amplifier once the installation
has been completed and checked.
7
Power supply input with fuse
Connect the IEC cord supplied to this input, and after
checking the voltage supplied, connect it to the mains.
If necessary, replace the fuse with one of the same type
and rating.
