3. Operating Instructions
This section provides an overview of the main controls and their functions for operating your VMX100USB mixer.
3.1 Channel Controls
- GAIN: Adjusts the input level for each channel. Set this to achieve a strong signal without clipping (distortion).
- HIGH/MID/LOW EQ: Three-band equalizer for each channel to shape the sound. Turn knobs to cut or boost frequencies.
- CHANNEL FADER: Controls the volume of each individual channel.
- PHONO/LINE/USB Switch: Selects the input source for each channel (Phono, Line, or USB audio from computer).
3.2 Master and Monitoring Controls
- MAIN LEVEL: Controls the overall output volume of the mixer to your amplifier or powered speakers.
- LEVEL METER: Visual display of the output level. Aim for levels in the green/yellow range, avoiding consistent red (clipping).
- PFL (Pre-Fader Listen): Activates headphone monitoring for a specific channel before its fader.
- HEADPHONES LEVEL: Adjusts the volume of the headphone output.
3.3 Crossfader and BPM Counter
- CROSSFADER: Blends between Channel 1 and Channel 2. Move it left for Channel 1, right for Channel 2, and center for a mix of both.
- CURVE: Adjusts the response curve of the crossfader (soft for smooth transitions, sharp for quick cuts).
- DUAL BPM COUNTER: Automatically detects and displays the beats per minute (BPM) of the audio on each channel.
- SYNC LOCK / BEAT ASSIST: Aids in beat matching by visually indicating synchronization and allowing manual tap tempo.
- TEMPO DIFFERENCE / TIME OFFSET: Provides visual feedback on the difference in tempo and time between the two channels, assisting with beat matching.
3.4 USB Audio Interface Usage
When connected to a computer via USB, the VMX100USB functions as a 2-in/2-out audio interface. You can record your main mix directly into your digital audio workstation (DAW) or playback audio from your computer through the mixer's channels. Select "USB" as the input source on the desired channel to play audio from your computer.
4. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Behringer VMX100USB mixer.
- Cleaning: Use a soft, dry cloth to clean the exterior of the mixer. For stubborn dirt, a slightly damp cloth can be used, but ensure no liquid enters the unit. Avoid abrasive cleaners or solvents.
- Dust Protection: When not in use, cover the mixer to protect it from dust and debris, which can affect faders and knobs.
- Storage: Store the mixer in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity.
- Fader Care: The faders are precision components. Avoid excessive force or spills on them. If they become stiff or noisy, consult a qualified service technician.
