Installation :
We strongly encourage you to only use a fixation system or support recommended by the manufacturer or supplied with this product. Carefully follow the installation instructions and use the adequate tools. Always ensure this unit is firmly fixed to avoid vibration and slipping while operating as it may result in physical injury.
Ceiling or wall installation:
Please contact your local dealer before attempting any ceiling or wall installation.
Ventilation:
The cooling vents ensure a safe use of this product, and avoid any overheating risk. Do not obstruct or cover these vents as it may result in overheating and potential physical injury or product damage. This product should never been operated in a closed non-ventilated area such as a flight case or a rack, unless cooling vents are provided for the purpose.
Heat exposure:
Sustained contact or proximity with warm surfaces may cause overheating and product damages. Please keep this product away from any heat source such as a heaters, amplifiers, hot plates, etc…
Electric power supply:
This product can only be operated according to a very specific voltage. These information are specified on the label located at the rear of the product.
Power cords protection:
Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at lugs, convenience receptacles and the point where they exit from the fixture.
Cleaning precautions:
Unplug the product before attempting any cleaning operation. This product should be cleaned only with accessories recommended by the manufacturer. Use a damp cloth to clean the surface. Do not wash this product.
Long periods of non use:
Disconnect the unit’s main power during long periods of non use.
Liquids or objects penetration:
Do not let any object penetrate this product as it may result in electric shock or fire. Never spill any liquid on this product as it may infiltrate the electronic components and result in electric shock or fire.
This product should be serviced when:
Please contact the qualified service personnel if :
- The power cord or the plug has been damaged.
- Objects have fallen or liquid has been spilled into the appliance.
- The appliance has been exposed to rain or water.
- The product does not appear to operate normally.
- The product has been damaged.
Inspection/maintenance:
Please do not attempt any inspection or maintenance by yourself. Refer all servicing to qualified personnel.
Operating environment:
Ambient temperature and humidity: +5 – +35°C, relative humidity must be less than 85% (when cooling vents are not obstructed). Do not operate this product in a non-ventilated, very humid or warm place. Installation in a saline environment or near a swimming pool may cause accelerated oxidation and invalidate the warranty.

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.

Device presentation

Power switch
Switches the amplifier on and off. When the amplifier is on, the VOL potentiometer LED is lit.
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 reinjected 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).
Output terminals
Connect your speakers to these terminals. The two terminals are wired in parallel.
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.

Application

Use high-quality cables to connect your speakers. To avoid short-circuits, check that the cable strands are correctly twisted before connecting them to the output terminals. When connecting your loudspeakers to the amplifier, be sure to observe the correct polarity. Connect transformer-equipped speakers to the + and – output terminals. The two outputs are wired in parallel. Take care to distribute the connected loudspeakers so that the sum of the powers of all the loudspeakers does not exceed the maximum power of the amplifier.

Below is a table showing the correspondence between amplifier/loudspeaker distance and cable cross-section, to avoid any deterioration in signal quality.

Maximum 100 V line length

Power| Minimum impedance| Installed cable cross-section
1,5 mm²| 2,5 mm²
150 W| 67 Ω| 800 m| 1300 m
300 W| 33.5 Ω| 400 m| 700 m
500 W| 20 Ω| 180 m| 350 m
