3.1. Controls

3.1.1. Mains power switch [1]

The on/off switch is located on the rear panel and isolates the
mains power supply to the E-PAC. The MUTE/POWER switch [2]
on the front panel has the functions ON/MUTE/STANDBY and
does not isolate the E-PAC from the mains power supply.
− off: the E-PAC is isolated from the mains power supply except
the overvoltage protection circuit. The power consumption is
very low (2 W typical).
− on: the E-PAC is switched on. Via remote or the MUTE control
the E-PAC can be switched to standby mode. To indicate
standby mode the display remains active.

3.1.2. MUTE/POWER switch (green LED) [2]

When the rear panel mains power switch is set to the on position,
the combined MUTE/POWER switch can be used to place the
E-PAC either in mute or standby mode. The switch incorporates a
green LED indicator which indicates three different states - ON,
MUTE and STANDBY.
− LED on » ON (unmuted): the E-PAC is powered on and
ready for use. A brief press of the MUTE/POWER switch will
mute the E-PAC, a longer press places the E-PAC in standby
mode.
− LED
regular
the E-PAC is muted. In the mute state, the input signal is muted
but the power amp is still powered and connected to the
speaker output. The E-PAC is unmuted by briefly pressing the
MUTE/POWER switch. A longer press of the MUTE/POWER
switch will place the E-PAC in standby mode.
− Regular short flashes (1:8 duty cycle): » STANDBY:
in standby mode the loudspeaker output is electronically
isolated and the E-PAC idles, drawing minimal mains power.
Only the most essential functions are provided. Display and
network remain functional, the display illumination is switched
off after 10 seconds. Pressing the MUTE/POWER switch powers
on the E-PAC ready for use. The E-PAC may also be powered
back on by remote control from standby mode.
