CAUTIONS
- Do not make any connections when your device is powered on.
- Put your device in a dry and well-ventilated place, far from a source of heat.
- Avoid putting something on your amplifier.
- Avoid any short-cut.
- Strictly respect polarity + & -, as well as the left and right connections.
- Do not plug-in two speakers in parallel on the same output.
ADVISES
- To optimize the performance of your device, you should switch it on at least half an hour before any listening, the time for the power stage to reach its ideal working temperature.
- Your device will give you optimal listening quality after this timelapse.
- Between two uses, it is, therefore, preferable to let the device on so that it remains at its optimum temperature.
- At night or when you leave your home, it is best to use the main switch to turn off the device.
- To optimize the sound quality of your system, we recommend that you choose good-quality connection cords. Do not hesitate to ask your specialist dealer for advice.
- Your amplifier is equipped with a temporized switch on. A relay protects loudspeakers on the output power stage from over-voltage.

the input (11) at the rear of the appliance on MONO. PRE-OUT outputs of the
preamp must be connected to the Right inputs of each Amplifier.
