Front panel control

The front panel has a single control: a centrally located power on/off button.

POWER

Switches the unit on and off. Note that the modules are turned on individually to stagger the surge created when a powerful amplifier is switched on (i.e., it provides a ‘soft start’). This reduces the surge current drawn from the domestic power supply.

Status LEDs

A separate LED indicates the status of each of the seven channels of the P777.

The LEDs cycle through red, orange, then green to indicate the status from powered-up (initialised), stabilised and active respectively.

All LEDs are off in standby mode.

Operating procedure

Once the relevant connections have been made, the P777 can be switched on using the central button on the front panel.

Switching on

It is recommended that you switch on your pre-amplifier or controller before powering up the power amplifier.

Normal powering up is indicated by the following sequence of front panel LED indicators:

1.On pressing the power switch, all LEDs turn red.

2.After a short delay (about half-a-second), the centre LED turns amber.

3.The LEDs continue turning amber from the centre to the edges in pairs, at about one second intervals.

4.The centre LED turns green and a relay ‘click’ is heard.

5.The LEDs continue turning green from the centre to the edges in pairs, along with relay ‘clicks’, at about one second intervals.

In the unlikely event that the LEDs do not follow this sequence when the unit is powered up, or they behave abnormally at any time during use, then refer to the ‘Fault status indicators’ table on page 10 to discover why the amplifier is in protection mode.

Switching off

To shut down, switch the power amplifier off first, followed by the pre-amplifier or controller.

This eliminates the chance of any ‘thumps’ or power spikes being fed through to the power amplifier and potentially causing damage to the system.
