OPERATING VOLTAGE
WARNING!
A label above the mains power cable on the rear of the amplifier
indicates the selected AC mains operating voltage.
Connect the power cable only to the AC source referred to on the
label. The warranty will not cover damage caused by connecting to the
wrong type of AC mains.
For converting a 230 volt amplifier to 115 volts or vice versa, contact
Martin Audio Ltd or an approved Martin Audio dealer.
Martin Audio E series amplifiers use primary switching, i.e. the mains is
rectified directly before the transformer, which means that the power supply
is insensitive to the mains frequency.
Mains Connections
The amplifier is supplied with 1.5M of un-terminated 3-core cable and
should be connected as below to a suitable plug or outlet.

EARTH (CHASSIS)
Once connected to a suitable AC supply, the amplifier can be started with
the power switch. When you power up the amplifier it takes a few seconds
to self-check. (This is known as the "soft start" sequence). The fans will
start and the red power "ON" LED and red "max" power LED’s will
illuminate to show the amplifier is operational. If everything is ok the “max”
power LED’s will extinguish and the power LED will remain "ON".
Grounding
The E1300 is equipped with a ground lift switch at the rear of the amplifier.
Depending on the system wiring configuration, it may be necessary to
'LIFT' the signal ground. When the signal ground lift switch is operated it
interposes an RC network between chassis ground and signal 0V breaking
any ground loops that may be causing hum.
For compliance with the EMC directive (conducted emissions), the E1300 is
provided with an AC mains filter. This requires the mains earth to be
connected to ground at all times.
RISK OF SHOCK!
For safety reasons never operate the amplifier with the mains
earth disconnected.
