This document describes the GLEMM MXD 06, MXD 08, and MXD 10 Microphone Mixers, which are designed for a variety of audio applications, including musical performances, conferences, gyms, and schools. The manual provides detailed instructions for operation, technical specifications, and safety precautions.
Function Description:
The GLEMM MXD series mixers are designed to combine multiple audio input signals, process them, and output a mixed signal. They support both microphone and line-level inputs, offering flexibility for various audio sources. Key functionalities include:
- Mixing: Combining signals from multiple channels.
- Equalization (EQ): Adjusting the tonal balance (treble, midrange, bass) of individual channels and the overall mixed signal.
- Effects (FX): Applying digital effects to audio signals.
- Phantom Power (+48V): Supplying power to condenser microphones.
- USB Playback/Recording: Playing MP3 files from a USB stick or external disk and recording audio to a USB device.
- Bluetooth Connectivity: Receiving audio wirelessly from smartphones or other Bluetooth-enabled devices.
- Monitoring: Allowing users to listen to specific channels or the main mix through headphones.

Usage Features:
- Input Channels (LINE IN/MIC 1-2): XLR connectors (1) provide balanced signals and +48V phantom power for condenser microphones. A 6.3mm unbalanced socket (2) is available for dynamic microphones.
- Caution: Do not connect unbalanced sources to XLR inputs when +48V phantom power is active. Always disable the channel when connecting/disconnecting cables or activating/deactivating phantom power to avoid audio interference.
- TRIM (3): Adjusts the input signal's gain level. Set the VU-meter to "O" so the PEAK LED does not remain steadily lit.
- EQ (4): Three controls (High, Mid, Low) adjust the tonal characteristics of the channel's audio signal.
- FX (5): Controls the level of the effect applied to the channel's audio signal.
- PAN (6): Distributes the signal level between left and right channels for stereo imaging.
- ON/OFF (7): Activates or deactivates the mixing channel. The button illuminates when active.
- SLIDER (8): Adjusts the channel's volume. The PEAK LED indicates signal peaks and should not remain steadily lit. The SOLO button enables headphone pre-listening for the channel.
- CD/TAPE (9): Input/output for line-level signals, often used with recorders. The mixing volume is controlled by a rotating knob (28).
- MAIN OUT (10): Two XLR sockets provide the mixed signal output to an amplifier.
- PHANTOM +48V (11): Activates +48V power on XLR channels 1-4 for condenser microphones.
- Warning: Do not connect other microphones when this button is pressed to avoid damage.
- DISPLAY BT/MP3 (19): Shows information about the current track (time, track number), track repeat settings, and Bluetooth status.
- DISPLAY DSP (12): Shows the current DSP effect (16 settings available).
- USB SOCKET (18): Connect a USB stick or external disk (FAT32 format) to play MP3 files.
- DSP MODULE (13, 14, 15): Main knob (13) selects and confirms effects. Two rotating controls (14, 15) adjust effect level and parameters.
- MP3/REC MODULE (20): Includes track selector, treble/bass controls, buttons for song playback (one, all, folder, random), and recording. Pressing the REC button sets the recording function; pressing the main knob starts/pauses recording; pressing REC again stops recording.
- VU METER (21): Displays output or pre-listening signal levels and peaks. Ensure levels are not too high to prevent distortion or damage.
- EFFECT (22): Adjusts the overall effect level on the main mix.
- MP3/BT (23): Adjusts the volume of the MP3 module in the mix.
- MAIN L/R (24): Two sliders adjust the master output volume.
- BLUETOOTH (25): Press and hold to activate the Bluetooth receiver. Pair with a smartphone to send audio. Press and hold again to exit. Basic controls (forward, back, play/stop) are available on both the mixer and smartphone.
- PHONES SOCKET (26): 6.3mm jack for headphones. Press "SOLO" on a channel to pre-listen. The PFL LED next to the headphone volume (30) lights up, and VU-METERS (21) show the headphone level.
- AUX RETURN (29): Adjusts the level of the AUX return signal.
- PFL/PHONES (30): Adjusts the headphone pre-listening signal level.
