4.1. Controls

4.1.1. 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.

4.1.2. MUTE 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 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.
