As there is only one open slot ○ 1 available for module, so only one of the following CHIAYO
modules can be used at any one time:
1.wireless receiver module
2.digital recorder player module
3.Bluetooth receiver module
When a wireless receiver module is plugged in slot ○ 1 , two receiving antennas must be
installed at antenna sockets ○ 14 and ○ 32.for a drop-out-free reception.
MMA-3000 is a 2.1 channel multimedia mixer amplifier, its digital class-D amplifier can drive a
stereo L / R speakers plus a subwoofer!
Operating the WIRED MICROPHONE
1. Connect the wired microphone to the MIC IN jack (XLR ○ 31) on the rear panel.
2. Set the LINE / microphone’s volume level ○ 3 to minimum before turning on the amplifier.
3. After the unit is ON, adjust the microphone’s volume ○ 3 to a desired level.
Connecting to EXTERNAL AUDIO INPUTS
This amplifier’s compatible unbalanced audio inputs include a Ø3.5mm phone jack ○ 28 , an
RCA R/L jacks ○ 29 and a Ø 6.3mm phone jack ○ 30. Their volume controls are ○ 6 , ○ 7 and ○ 3 .
SUBWOOFER OUTPUTS ○ 20 ○ 21
This amplifier’s compatible subwoofer outputs include a Ø 6.3mm phone jack ○ 20 and a phoenix
connector ○ 21 . The volume control for subwoofer is ○ 12 .

-3-
The output could deliver 100W power to a 2Ω Subwoofer speaker.
The Subwoofer Crossover tone control ○ 19 has an adjustable range from 60Hz to 200Hz.
When a phase swift difference is detected, please use the phase switch ○ 18 to correct it.
L / R SPEAKER OUTPUTS ○ 22 ○ 23 ○ 24
This amplifier’s compatible speaker outputs include a Ø 6.3mm phone jack (R/L) ○ 22 ○ 24 and a
Phoenix connector ○ 23 . The volume control for L/R speakers is ○ 11 .while ○ 8 ○ 9 ○ 10 are the
balance, bass and treble controls.
DC OUTPUT ○ 16
This amplifier can provide 12V power supply to an external device.
USB charging ○ 17
This amplifier can provide a 5V power supply to power or charge an external device such as
Smartphone and Tablet computer.
Operating the VOICE PRIORITY ○ 5
Besides wired microphone, the device can also detect the audio signal from the plug-in module.
When using the wireless microphone, position the MUSIC-WR ○ 2switch to WR (Wireless
Receiver). When using other module like MP3 or Bluetooth, position the switch to MUSIC to
prevent VOICE PRIORITY from mistaking the music as microphone audio.
When the VOICE PRIORITY switch ○ 5 is ON, the ducking function will be activated. While the
music is playing, a voice input from either a Wired or Wireless Microphone will temporarily
override and lower the volume of the background music and voice could be heard more clearly.
When no microphone signal is detected, the music volume will automatically return to its
previous level.
ALD (Assistive Listening Device) OUTPUT ○ 25
For the benefit of hearing impaired audiences, MMA-3000 has an additional Ø 3.5mm ALD
output ○ 25 which can be connected to an ALD amplifier or transmitter to send the mixed audio
signal to whoever is wearing an ALD headphone.
An ALD output volume control ○ 26 is for the setting of the ALD volume to an appropriate level
to be transmitted.

module. Select a channel that corresponds to the transmitter. When transmitter is turned on,
either A or B diversity indicator will flash to indicate that signal has been received.
SQUELCH (SQ) setting
When a channel is in use and undesired interference signal is received, turn the SQ in
clockwise direction to make the receiver less sensitive and thus less susceptible to interference.
If this still does not solve the problem, it means this frequency is not applicable at current
position. Please switch over to the next channel.

singing purposes whereas Level 4 is for use of microphone on tripod mount for speech
purposes. When Level 4 setting is used for close proximity singing, high SPL input will result in
undesirable distortion in the output.
After performing setting changes, you could turn the protective cover 180°in either direction to
block the buttons from being accidentally adjusted.
