Introduction

The ART MX622BT Six Channel Stereo Mixer with BLUETOOTH and Effects Loop is a versatile single high rack mixer combining three balanced microphone or line level inputs with three stereo line inputs plus a stereo Bluetooth input into a single stereo line level mix. Each mono balanced XLR input includes fully variable Input gain, Mic/Line switch, Clip indicator, and selectable 15 Volt Phantom power. Three stereo line level inputs are also provided via RCA type jacks with separate Level controls for each stereo pair. The front panel also has a 1/8-inch input for portable audio device input. The Bluetooth input supports Bluetooth 5.0 and has its own level control and Pairing/ ON/OFF switch. An external effects loop section provides a mono Send from the three Mic/Line channels to external equipment and stereo Returns with Effects Level and In/Out switch. Stereo Record output RCA jacks provide full-level signal of the entire mix at all times. Main outputs are stereo balanced 1/4-inch TRS with Master Level and full range Bass/Treble equalization. The built-in power supply and single high 19-inch rack mount format allows for easy installation and reliable operation.

Operation

Verify proper voltage selection on the IEC style power connector for your location. Connect the AC cord to a grounded AC outlet.

Connect Mics or balanced Line inputs to the XLR sockets.

For Mic channels requiring phantom power (for condenser mics), move the DIP switch to the down position to activate phantom power for each XLR input.

Set each Mic/Line switch as required for the type of input signal level.

Connect stereo signal sources to input channels 1, 2, and 3 using RCA type unbalanced cables or an 1/8-inch stereo jack on the front panel for channel 3.

To patch-in effects, using three shielded TS (unbalanced) cables connect the EFX Loop Send jack to the input of the effects unit and the unit's stereo outputs to the Left and Right EFX Loop Return jacks.

Once the MX622 is connected to the main mixer, computer interface, or power amplifier, apply a test signal, set the EFX Loop In/Out switch on the front panel to the IN position, and adjust the EFX Level control for the desired effects intensity.

The Left and Right EFX Loop Return jacks may alternately be used as a stereo line input with its own level control and In/Out switch.

Connect either the 1/4-inch balanced Left and Right Main Output jacks or the RCA Record Out jacks to the input of the mixer, tape deck, computer, or power amplifier with the appropriate balanced or unbalanced, shielded cables.

Switch on the power and set the Master Level to the 1/2 way setting, then adjust the input channel Level controls as required for the best mix and level while checking the Mic/Line channel CLIP LEDs for activity. Turn down any channel with CLIP activity until the LED is on during extreme peaks only.

Adjust BASS and TREBLE controls for the desired balance. The mid position has flat frequency response.

Re-adjust the Master Level as required for best signal level.

Bluetooth

Bluetooth™ Section

The MX622BT is capable of receiving streaming audio over Bluetooth™ from devices such as smartphones and laptops. Pairing your device with the MX622BT is simple and gives you the freedom to play your music wirelessly.

1. Pairing / Bluetooth™ Pair Button: When the Pair Button is pressed for 4sec, the Bluetooth™ audio connection is available for pairing. After pressing the Pair Button, go to the Bluetooth™ menu on your streaming audio device. You will see a device named “MX622Bt_vx”. Select this device to initiate pairing. Once you see the “MX622Bt_vx” device connected, you will be able to stream audio to the MX622BT.
2. Disconnecting: Disconnecting the paired device requires the pairing button to be pressed twice in one sequence. The blue LED will not light once the paired unit has been disconnected. Then the LED will resume blinking slowly to be paired again.
3. Bluetooth™ Status Indicator: The blue status indicator alerts the user to the current status of the Bluetooth™ connection. A fast-blinking light indicates an available, unpaired connection. Constant steady Blue light means there is an active connection. No light means that Bluetooth™ is disabled or a connection has been lost.
4. Bluetooth™ Level Control: Use this control to set the audio level for the Bluetooth™ connection. Level can also be controlled directly at your streaming device.

The MX622BT Bluetooth™ operating range is rated for 30 meters (100 feet) line of sight. The quality of the link can be affected by an excess of traffic in the 2.4GHz band or structures between the streaming device and the MX622BT unit.
