ART MX622BT

Product overview

The ART MX622BT is a six channel stereo rackmount mixer with Bluetooth 5.0, an effects loop and master bass and treble EQ, combining wired and wireless sources with up to three microphones in one rack space.

Channels 1 to 3 have stereo RCA inputs, and channel 3 also has a 1/8 inch stereo input on the front panel. Channels 4 to 6 have mono XLR inputs that are switchable between mic and line level, with switchable phantom power. The rear panel has balanced 1/4 inch and stereo RCA outputs. Each input has a dedicated level control, the master section adds 2-band EQ, and a switchable effects loop integrates external signal processing; the effect return jacks can also be used as an additional stereo input controlled by the Effects Level knob. ART describes it as particularly well suited to retail, restaurant, corporate and academic settings that need to combine wired and wireless A/V sources with up to three microphones.

Bluetooth input

The MX622BT receives streaming audio over Bluetooth from devices such as smartphones and laptops. Holding the Pair button for 4 seconds makes it available for pairing; the device then appears as "MX622Bt_vx" in the Bluetooth menu. Pressing the button twice in one sequence disconnects the paired device. The blue status LED blinks fast when an unpaired connection is available, lights steadily when connected and stays off when Bluetooth is disabled or the connection is lost. The range is rated at 30 metres (100 feet) line of sight; heavy traffic in the 2.4 GHz band or structures between the device and the mixer can affect the link.

Microphone and line inputs

The three balanced XLR inputs accept microphones or balanced line sources, each with a Mic / Line switch, level control and clip LED; rear DIP switches add 15 V phantom power for condenser microphones on each XLR channel. Three stereo RCA inputs take line sources, with a parallel 1/8 inch stereo jack on the front panel for channel 3.

Effects loop and outputs

A mono effects send carries the three mic / line channels to an external processor, and stereo returns bring it back with its own Effects Level control and In / Out switch; the returns can alternatively be used as a stereo line input. Main outputs are balanced 1/4 inch TRS with master level and full range bass and treble EQ (± 12 dB at 100 Hz and 10 kHz, flat at the mid position). Stereo RCA record outputs provide the full-level signal of the entire mix at all times.
