Mains Connection; Signal Input Connections - Ecler APA1400 Bedienungsanleitung

3.2. Mains connection

The APA amplifiers are fed with alternate currents, depending on the country, of
110-120, 220-240V 50/60Hz. (see characteristics in the back of the unit) consuming:
MODEL
CONSUMPTION
The mains cables must not be near the shielded cables carrying the audio signal, as this
could cause humming.
To protect the amplifier from eventual over charges of consumption, there are five time
lag fuses incorporated (see chart), two situated in each power module and the fifth in the primary
transformer supply. Should a fuse blow, it must be replaced immediately by one of identical
characteristics. Should it blow again please consult our Technical Service Department. NEVER
REPLACE THE FUSE WITH ANOTHER ONE WITH A HIGHER VALUE.
CAUTION: Fuse substitutions have to be performed by a qualified technician.

3.3. Signal input connections

The signal input connectors are of XLR-3 type (19, 21), electronically balanced. The pin
assignment is as follows:
For unbalanced connection short-circuit pin 3 to pin 1.
The "STK OUTPUT" (18, 20) are in parallel with the inputs and are used to supply the
same input signal to other amplifiers or sound systems. This signal output connectors are of jack
1/4" type. The pin assignment is as follows:
The input impedance is 22KΩ (balanced) with a nominal input sensitivity of 0dBV(1V).
This impedance makes possible to parallel several amplifiers without loosing audio quality.
