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.

OPERATION STEP
 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, 5, 6 or 7 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 MIC2-4 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 2-6 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
The mixer-amplifiers are built-in a built-in media player which includes Mp3/FM/Bluetooth. Pressing the Mode button to switch the
media player among Mp3/FM/Bluetooth according to the LED display, where there is one IR remote control enable to operate the
media player remotely around 10 to 30 meters, this media player output volume control also could be controlled by the “TEL” volume
knob.
Bluetooth
The Bluetooth function allows connection of a smart phone or tablet to the media player section for playback of stored files or
streamed digital audio. In order to enable this function, it will be necessary to pair the sending device to the receiver as follows.
1. Open the Bluetooth settings menu on the smart phone or tablet (or other sending device)
1. TF card input
2. LED display
3. IR sensor
4. USB input
5. Mode to select MP3/BL/FM
6. Play
7. Folder
8. RPT repeat
9. Previous & volume- decrease
10.
Next &
volume + increase

8 / 10 www.cmxaudio.com
2. Scan for Bluetooth devices and look for it in the list of available devices (ensure that the amplifier is powered on and within 30-50
meters reception range)
3. Select the blue tooth and the sending device should confirm that it is connected as an audio device
4. Play audio from the sending device, ensuring that volume controls are not turned down/muted
5. Turn up the MEDIA volume control 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. Holding the Previous track or Next
track buttons will adjust the output volume of the player.
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.
