1. Front Mic Input Jack Channel 1 balanced microphone input. Once inserted, it shall bypass the rear input connection.
2. Input Level Controls Individual control knobs for input 1 to 6.
3. Tone Controls Bass and treble controls for mixed signals.
4. Master Control Master volume control for mixed signal ; speaker and line outputs.
5. Power Switch Mains switch for ac input. Switching off the switch shall not disconnect the DC supply to the unit if it is connected to back up battery. It is recommended that the DC back up is connected to the battery charger's EM output instead of directly to the batteries. This shall prevent idle drain of the battery bank.
6. Speaker Zone Selector 100V line ouput can be channeled into 3 output zones and each zone can be selected via these switches with ALL CALL. Alternatively, selected can also be done via remote paging microphone, ie. PM1060.
7. LED Indicators LED indicators for Power, Protect mode and 4 segment output level meter.
8. Circuit Breakers Resettable circuit breakers for ac and dc inputs of 5 and 10A respectively.

9. 24V DC Power Input Input to battery bank for back up supply with 10A rating at full load.
10. Low Impedance Output For connections to speaker output with 4 Ohm min. This shall bypass the speaker zone selector. Ensure that the load does not exceed to power rating.
11. 100V Line Speaker Terminals Allows connection of speakers with matching transformer to the unit under 3 zones. Total load shall not exceed the specified rating of the power amplifier.
12. Line Output Line level output for connection to external link. The output level is controlled by the Master volume controller.
13. Remote Paging Zone Selection External control of speaker zone selection via negative triggering method. Connection to Amperes PM1060 is recommended.
14. Mic / Line Level Switch Inputs to the unit can be either mic or line level. Select the required input type by using these switches and plug the input source to the appropriate jack. Stereo phone jack for balanced mic input whereas the RCA jack is for music source unbalanced line input. It is recommended that at any one time, only one type of input source is connected to the amplifier.
15. RCA Jack For unbalanced line input sources such as CD player, etc.
16. Mute Level Control Input channel 1 and 2 has priority over other channels, such that the presence of the signal shall mute other input sources. The level of mute or mixing is controlled by this switch, which can fully or partially mute or normal mix.
17. XLR inputs 2 XLR balanced inputs are available for microphones.
18. Phantom Power Switch 12V DC phantom power is available for input channel 1 and 2, which is suitable for connection to condenser microphones. For normal mic inputs, it is recommended that the phantom power feature is turned off.
