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.

Speaker Terminal

This terminal is 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: 60W (MA-60D) or 120W (MA-120D). 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.

Media Player

1. TF card input
2. LED display
3. IR sensor
4. USB input
5. Mode to select MP3/BL/DAB+/FM
6. Play
7. Folder
8. RPT repeat
9. Previous & volume- decrease
10. Next & volume + increase

The built-in media player includes MP3/Bluetooth/FM/DAB+ functionality. Press the Mode button to switch between the sources MP3/Bluetooth/FM/DAB+. The LED display shows the current source. The IR remote can also be used to control the media player  up to a distance of 10 to 30m.

Holding the Previous track or Next track buttons will adjust the output volume of the media player.

Bluetooth

The Bluetooth function can be used to use a smart phone or tablet for playback of stored files or streaming audio. In order to use this function, it is necessary to pair the sending device and the receiver. Follow the next steps:

1. Press the “Mode” button on the Media player to select “Bluetooth” to activate Bluetooth, the receiver becomes visable and is ready to pair.
2. Open the Bluetooth settings menu on the smart phone or tablet (or other sending device).
3. Scan for Bluetooth devices and look for it in the list of available devices.
4. Select the amplifier, the sending device should confirm that it is now connected as an audio device.
5. Play audio from the sending device, ensuring that volume controls are not turned down/muted.
6. Turn up the Master volume on the amplifier to the required level.

If the Bluetooth signal is lost, it may be necessary to re-select the Bluetooth on the sending device.

The Previous, Next and Play/pause buttons will operate in Bluetooth as remote playback controls.

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.

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.
