• Front Panel Controls & Features

1. POWER Switch
Push the top part of the knob (marked l)to switch the amplifier ON. Push the bottom part of the knob (marked 0) to switch the amplifier OFF.

2. Volume Control for Channel A
It is used in Stereo/Mono mode, for adjusting the volume level of channel A.

3. CLIP Level Indicator LEDs for Channel A & B
One separate red LED provided for each channel. Continuous glow of LEDs indicates that there is excessive signal being fed to the input of the amplifier resulting in clipped and distorted output levels. In such cases, it is advisable to reduce the input signal or reduce the volume setting. Otherwise, the amplifier may go into protect mode and signal will mute.

4. Power LED ON/FAULT
This LED glows green when the amplifier is switched ON. This LED will glow orange if amplifier is in fault conditioning against over voltage cut off and DC fuse blown OFF.

5. Signal Indicator LEDs for Channel A & B
Indicate the presence of signal in channel A and B respectively.

6. Volume Control for Channel B
It is used in Stereo/Mono mode for adjusting the volume level of channel B.

7. Temperature Indicator LEDs for Channel A & B
Separate yellow LEDs provided for each of the two channels A & B. Glowing of these LEDs indicates excessive temperature of the output devices or transformer. The special circuitry then mutes the input signals. The amplifier will remain at mute status, till the devices cool down to normal temperature. Switch OFF the amplifier to cool down and then switch ON to continue.

8. Protect Indicator LEDs for Channel A & B
Separate orange LED provided for each of the two channels A& B. These LED’s glow when the output is shorted or the output is overloaded or the input is too high or DC voltage is present on the speaker output. In any of these conditions the amplifier goes to protect mode. To reset the amplifier, switch OFF the amplifier, turn volume control to zero, correct the fault, and switch ON the amplifier after 5-10 seconds. Increase the volume control slowly to the desired output below Clip level.

• Limiter Setup

In this series, limiter is active in both conditions i.e. ON and OFF. ON/OFF is two different modes of limiter setting.
LMITER ON: In this mode, maximum power output of the amplifier will be limited to unclipped level. Even the Input signal higher than the given sensitivity, the power output of the Amplifier will be unclipped. Due to which the sound quality will be pleasant. Therefore, it is recommended to use this limiter setting for most applications except subwoofer usage.
LIMITER OFF: In this mode, maximum power output of the Amplifier will be limited to a state where output is available at just clipped level. This mode is suitable for subwoofer applications. In this mode, limiter is still active even if the input is much higher than rated sensitivity. In this condition, output will be same as defined.

Tips for Safe Operation

The amplifier must be connected to an AC earthed mains outlet that can deliver the maximum power required. The use of extension cables or adaptors should be avoided as this can jeopardize correct current delivery to the amplifier.
All connections must only be carried out or changed with the amplifier switched OFF & the AC mains supply disconnected.
Ensure proper impedance matching. For continuous safe operation, resultant impedance of the speakers is recommended as 4 or 8 ohms in mono/stereo modes.
For 4 ohm applications, it is recommended to use speakon connectors only.
Use of cable 40 / 36 or thicker is recommended to prevent power losses in speaker cables.
The level of input signal should not exceed the specified input sensitivities. Excessive input signal levels result in over driving of input circuit which leads to saturated / distorted output at speaker terminals.
Do not operate the amplifier with continuously glowing CLIP LED. The respective volume control of the channels must be adjusted so that the output level does not clip and distort.
Do not obstruct the front or rear of the amplifier for necessary intake of air. This is a fan cooled amplifier.

• Protections & Installations

Thermal Protections

Output Devices/Transformer

In case of excessive heating of the output devices or transformer, the thermal protection circuits will bring the audio signal to mute status. Onset of thermal protection circuit is indicated by glowing of TEMP LEDs (yellow) in each channel. To restore normal operating conditions, it is recommended to switch off the amplifier for cooling and then switch ON again after cooling and checking the speaker connections.

DC, RFI Protection

Inbuilt circuits are provided to protect the loudspeakers from any offset DC voltages. Also suppression filters at primary and secondary power supplies have been inbuilt, to reduce some RF interference.

Overload / Short Circuit Protection

Protection circuit is provided in both channels for the safety of output devices in case of overload or mismatch of impedances at the outputs. This circuit brings the input signals to mute condition, and set will be in protect mode. To reset, switch OFF the amplifier for few seconds, remove the short circuit or overload and than switch ON for normal operation.

19″ Rack Installation

The amplifier is designed for use in a standard 19″rack with height of 2U units.
In order to provide sufficient support base to the heavy amplifier, it is essential to use the 19″ rack system with side support channels.
The installed amplifier, should be well supported by the side support channels as well as rigidly fixed on to the rack through the two rack mount side brackets duly fitted with ‘U’ type handles, as shown in the figure below:

Side Support Channel
