1 Balanced 6.3 mm Jack Input
This TRS stereo jack connector accepts an input signal (balanced/unbalanced) to drive the respective channel. If the signal is
unbalanced, kindly use a mono (TS) connector.
2 Balanced XLR Input
This XLR connector accepts an input signal (balanced/unbalanced) to drive the respective channel. If the signal is unbalanced, pin 2
can be used for the signal and pin 3 connected to the earth.
3 Output Binding Post
The binding post output is used to pick up the amplified signals individually in the stereo mode & in combination in the bridge mode.
4 Output Speakon Connector
Use this connector for picking up the amplified signal of CH 1 & CH2 and signal for bridged configuration.
5 Power Cable
This cable is used to supply the required power to the unit.
6 Circuit Breaker
The circuit breaker is provided to avoid amplifier failure caused due to a sudden surge or continuous high current supply.
7 Configuration Switch
This three-way switch is used to select between the three operational modes: mono, stereo and bridge.
8 Sensitivity
This switch is used to set the input sensitivity either at 0.775V or at 1.2V depending on the source.
9 Frequency Adjustment Knob
When the filter switch is at SUB or at the LOW CUT position, use this knob to adjust the frequency.
10 Filter Switch
Use this switch to select between the following two filter types.
SUBWOOFER: This is a low-pass filter. The amplifier reproduces frequencies that are lower than the cut-off set by the frequency adjustment knob.
LOW CUT: This is a high-pass filter. You can use this setting to filter out unneeded low or subsonic frequencies.
11 Bass Boost Switch
When you activate this mode, the amplifier adds low-frequency compensation to enhance the speaker's output.
Note: This switch is only effective when the FILTER switch is in the OFF position.
12 Limiter
Use this switch to activate or deactivate the built-in limiter. The limiter prevents distortion at the output level. When the output level
exceeds its maximum, an internal adjustment is made to prevent overloading. It is specially designed to protect the connected
speakers. When the amplifier is used to drive a subwoofer, switch the limiter off for added “punch”.
13 Air Exit Grill
Warm air exits from this grill to dissipate the heat generated and keep the amplifier cool.
For best results, do not obstruct the grill and clean the air filter whenever necessary.
14 External Earth Terminal
Use this for a ground/earthing connection if there are any humming problems.
