5
Main characteristics:
•
2 x 70W RMS (AMPACK2-70) or 4 x 70 WRMS (AMPACK4-70) amplifier at 4
Ω
•
Integrated power supply
•
AUTO STANDBY: when no signal is present, the AMPACK enters the Standby mode, reducing its
power consumption
•
Silent amplifier (convection cooling, without fan)
•
Stereo, parallel and bridged operating modes are available
•
VCA based remote control for volume (independent for each input channel)
•
EUROBLOCK connectors for input, output and VCA remote control
•
Additional RCA stereo input jack (AMPACK2-70 only)
•
Mono 1+2 switch (AMPACK2-70 only)
•
Independent gain controller for each channel, protected against unintentional changes
•
Integrated 100Hz high-pass filter
•
Direct mounting on 35mm DIN rail
3. INSTALLATION
3.1. Placement and mounting
AMPACK series is suitable for direct mounting on 35mm DIN rail
3.2. Mains connection
The amplifier is powered with alternate current, 220-240V 50/60Hz.
The amplifier should have an earth connection in good conditions (earth resistance, Rg=30
Ω
or less). The environment must be dry and dustless. Do not expose the unit to rain or water splashes,
and do not place liquid containers or incandescent objects like candles on top of the unit. Do not
obstruct the ventilation grids with any kind of material.
In case there is some type of intervention and/or connection-disconnection of the amplifier,
it is most important to previously disconnect the mains power supply. There are no user or
serviceable parts inside the amplifier.
You should avoid that the supply cable twists with the shielded signal cables, as this
could lead to unwanted hum.
Additionally, as a corrective measure of hum caused by situations like these ones, the
AMPACK series has a built-in high-pass filter with a 100Hz cut-off frequency and a front panel switch to
activate it.
