AMPLIFIER OPERATION GUIDANCE

100V Line System

• For 100V line systems, connect the amplifier to the first speaker in the system using double-insulated speaker wire which has adequate current rating to handle the total output of the amplifier.
• Connect the “100V” output terminal to the positive (+) connection of the speaker and “COM” output to the negative (-) connection of the speaker. Connect further speakers in parallel to the first speaker with all positive terminals and connected together and all negative terminals connected together as shown below.
• A 100V line speaker system can comprise of many speakers connected together. The determining factor for how many speakers can be used on a single amplifier is the power rating.
• For most purposes, it is advised to connect as many speakers as needed with a combined wattage of no more than 90% of the amplifier’s output power rating.
• The terminals of a 100V speaker are connected to a transformer and in some cases, this transformer may be “tapped” for different power ratings. These tappings can be used to adjust the wattage (and output volume) of each speaker in the system to help achieve the ideal total power of the system for the amplifier.
• The mixer amplifier is featured of 6 speaker zone outputs, either one of six zone or total six zone power loading shall be equivalent or no higher than the rated power of the amplifier.

Speaker Terminals

These terminals are offering 3 low voltage outputs 4Ω, 8Ω, 16Ω depending on your speaker combination. A 70V/100V commercial output is also available. Please note that one wire only should be connected to COM screw and one wire to the selected impedance or voltage. Multiple combinations cannot be done at the output level. Four different types of connections are provided. The low impedance section: 4Ω, 8Ω, 16Ω is designed for a small amount of speakers to be connected to your amplifier. The 70V/100V section is especially designed for a multiple speaker distribution. When using the 70V/100V output, speakers have to be equipped with 70V/100V transformer. The maximum amount of speakers to be placed on your distribution line is in relation to the power allocated to each speaker. The total wattage set on the secondary side of the transformers on your speaker line must not exceed the maximum RMS output power: 30W, 60W or 120W. Failure to respect this may cause permanent damage to the amplifier.

Speaker Connections

Operation Steps

• When all connections to the amplifier are made, turn all rotary controls down and switch on the power and a power “ON” LED will illuminate. Turn BASS and TREBLE controls to the 12 o’clock position (pointing straight up) and turn MASTER rotary control up part way for testing.
• Ensure a signal is being fed to one of the line inputs 1, 2, 3, 4 or 5 and gradually increase the volume control for that channel until the output is heard through the speakers. Turn up the MASTER to the maximum required volume level and reduce the channel volume control if necessary.
• Note: The initial test can be made using the built-in USB/SD/FM audio player. The output of the amplifier is represented on the level meter LEDs and care should be taken that the Red “0” LED is only lit momentarily during use. Anything longer than a short flash of this LED may be indicating distortion or clipping of the output signal and the MASTER should be turned down.
• If a microphone is connected to MIC1 input, make sure it is switched on and if it requires phantom power, make sure this feature is enabled. Gradually increase its volume control whilst speaking into the microphone until the required volume level is reached. The microphone should not be able to “hear” the speakers, which can cause feedback (squealing or howling noise).
• If the VOX feature is enabled, audio playback through channels 2-5 will be reduced in volume automatically when speaking into MIC 1, use its attenuator to increase or decrease the mute level.
• In addition to channel and MASTER volume controls, there are BASS and TREBLE EQ controls to adjust the tone of the overall output. At the 12 o’clock position, these controls are applying no effect to the signal (no boost or cut). Moving the BASS control clockwise boosts the low frequencies in the audio, whilst moving it anticlockwise will cut these low frequencies. Likewise, moving the TREBLE control clockwise boosts the high frequencies in the audio, whilst moving it anticlockwise will cut these high frequencies. Adjust these EQ controls to suit the type of audio signal or compensate for the room acoustics.

USB/SD Playback

• Push a USB pen drive into the USB port and/or an SD card into the SD card input.
• Press the CD/USB/SD button to ensure that the player is set to play from the required memory device. Press the PLAY/PAUSE button to play the current track and press again to pause as needed.
• Searching and playback of tracks is the same as described above for the CD player

FM Tuner
Press the FM select button to switch to the FM tuner function. Use the Previous or Next buttons to select a stored channel.

Tuning and storing stations

• Use the Forward/Reverse seek buttons to manually tune the frequency in steps of 0.05MHz Alternatively, press and hold the Forward/Reverse seek buttons to auto search for available stations. Upon finding a station, the auto search will stop, giving the option to store this station.
• At this point, pressing the PLAY/PAUSE button will flash a “00” channel number in the display.
• Use the Previous/Next buttons to select an appropriate channel memory.
• Press PLAY/PAUSE again to confirm and store the station into the selected channel memory.
• Auto search can be stopped at any time by pressing the Forward/Reverse seek buttons.

Mute On/Off

• Pressing the MUTE ON/OFF button will mute the output of the audio player.
• Pressing and holding the MUTE ON/OFF button will put the audio player in standby mode.
• Press this button again to restore functions from standby mode.

Music on Hold
This output will feed music on your telephone system or PABX for people waiting to be answered. A dedicated input should be available on your telephone system. Please refer to a qualified technician if you can’t identify this input. Outgoing signal should be connected to G and H.

Telephone Paging Input
This special TEL input will allow you to page in your PA system using your own telephone set or PABX system. At the end of the announcement, the system will return to its normal operation. The telephone paging input with priority except EMC (fire alarm) input. Final volume adjustment will be made with the Tel Paging volume control located on front panel.
