4 REAR PANEL
1.
AC POWER CORD:
AC Power Cord to 110V – 230V input. The rated power of the
equipment is self-switchable.
2.
GAIN CONTROL:
Allows the adjustment of the input sensitivity. There is an independent
gain control for each channel.
3.
LINE INPUT:
The line input supports balanced and unbalanced audio inputs. These inputs
are supplied through 3 pin and 3,818mm euroblock connectors (provided with the
equipment). Cable section range for each pole of this connector: 0,14 → 1,5mm2 (30 → 14
AWG). There is an independent line per channel.
4.
100V SPEAKER OUTPUT:
The speakers output for high impedance lines (100V) must be
connected between the positive and negative terminals of the output connector, according
to the speakers' polarity. The amplifier has two independent output channels. These outputs
are connected through 3 pin and 5,08mm euroblock connectors (provided with the
equipment). Cable section range for each pole of this connector: 0,5 → 2,5mm2 (22 → 12
AWG).
Never join the positive and negative ends, it can cause a short-circuit.
Never connect the low impedance speaker to these 100V ends, it could damage the
speaker.
5.
HIGH PASS FILTER:
The high pass filter function will activate or deactivate according to
the two channel configuration through the dip-switch. There are two high pass filter
independent channels.
6.
AUTO-STANDBY:
The auto-standby function will activate or deactivate according to the
two channel configuration through the dip-switch. It will activate when no input signal is
detected for 2 minutes. The amplifier will activate inmediatly when an input signal over
-40dB is detected.

(BA-2250) or 4
(BA-2500) SPEAKER OUTPUT:
Ω
Ω
The speakers output for low
impedance lines (8Ω (
BA-2250
) or 4Ω (
BA-2500
) ) must be connected between the Positive
and COM terminals of the output connector, according to the speaker polarity. The amplifier
has two independent output channels. These outputs are connected through 3
pin and
5,08mm euroblock connectors
(provided with the equipment).
Cable section range for each
pole of this connector
: 0,5 → 2,5mm2 (22 → 12 AWG).
Never join the positive and negative ends, it can cause a short-circuit.
Never connect the low impedance speaker to these 100V ends, it could damage the
speaker.
