[1]
Mains power switch
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.

Controls
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 flashing (1:1 duty cycle): » MUTE : 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.
