This manual provides detailed instructions on how to set up, operate, and maintain your TB-32 mixer to ensure optimal performance and longevity.

2. Setup

Before powering on your mixer, ensure all connections are made correctly.

1. 2.1 Unpacking and Placement

   Carefully remove the mixer from its packaging. Place the mixer on a stable, flat surface, ensuring adequate ventilation around the unit. Avoid placing it near heat sources or in direct sunlight.

2. 2.2 Power Connection

   Connect the provided power cable to the mixer's power input and then to a suitable AC power outlet. Ensure the mixer's power switch is in the OFF position before connecting to power.

3. 2.3 Input Connections

   • Microphones: Connect microphones to the XLR inputs (channels 1-28). For condenser microphones requiring power, activate the +48V PHANTOM power switch for the respective channel.
   • Line-Level Devices: Connect instruments (keyboards, guitars with preamps), CD players, or other line-level devices to the 1/4" TRS/TS inputs.
   • Stereo Inputs: Use the dedicated stereo input channels for stereo sources.

4. 2.4 Output Connections

   • Main Outputs: Connect the main outputs (XLR or 1/4" TRS) to your power amplifier or active speakers.
   • Monitor Outputs: Connect monitor outputs to stage monitors or headphones.
   • Auxiliary Sends: Use Aux Send outputs for external effects processors or additional monitor mixes.

5. 2.5 USB Connection

   For USB audio playback or recording, connect a USB cable from the mixer's USB port to your computer or USB storage device.

3. Operating Instructions

3.1 Powering On/Off

To power on, ensure all channel faders are down and the main fader is at minimum. Flip the power switch to ON. To power off, reverse the process: lower main fader, then channel faders, and finally flip the power switch to OFF.

3.2 Channel Controls (Channels 1-32)

• TRIM/GAIN: Adjusts the input sensitivity for each channel. Set this so the PEAK LED rarely illuminates.
• PAD: Attenuates the input signal by a fixed amount (e.g., -20dB) for very hot signals.
• +48V PHANTOM: Activates 48V phantom power for condenser microphones connected to the XLR input.
• EQ (Equalizer): Adjusts the tone of the channel. The TB-32 features a double 7-segment balance adjustable equalizer.
• AUX1/AUX2: Sends the channel signal to auxiliary outputs for monitors or external effects.
• PAN: Positions the channel signal in the stereo field (left to right).
• MUTE: Mutes the channel output.
• SOLO: Sends the channel signal to the headphone output for isolated monitoring without affecting the main mix.
• CHANNEL FADER: Controls the volume level of the individual channel in the main mix.

3.3 Dual FX Adjustment

The TB-32 features a powerful 48-bit DSP effect processor with 24 vocal DSP effects and 8 instrument DSP effects. Use the dedicated knobs to select the desired effect type. Turning the knob will automatically apply the effect. Adjust the FX send levels on individual channels to control how much of each channel's signal is sent to the effects processor.

3.4 Bluetooth and USB Playback

The mixer includes a built-in Bluetooth 4.0 module and a USB MP3 player. To use Bluetooth, activate the Bluetooth function on the mixer and pair it with your mobile device. For USB playback, insert a USB drive containing MP3 files into the USB port. Use the dedicated controls on the mixer's MP3 player section to navigate and play tracks.

3.5 Independent SOLO Key

Pressing the "SOLO" button on any channel allows you to monitor that specific channel's audio through your headphones without affecting the main mix. This is crucial for precise sound checks and troubleshooting during a live performance or recording session.

4. Maintenance

Proper maintenance will extend the life of your mixer and ensure consistent performance.

• 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 with a dust cover to prevent dust and debris from accumulating in faders and knobs.
• Fader and Knob Care: Periodically operate all faders and rotate all knobs through their full range of motion to prevent them from becoming stiff or intermittent.
• Storage: If storing for an extended period, disconnect all cables and store the mixer in a cool, dry place.

5. Troubleshooting

Here are some common issues and their solutions:

No Sound Output:

• Check if the mixer is powered on and connected correctly to the power amplifier/active speakers.
• Ensure the main fader and individual channel faders are raised.
• Verify that no channels are muted or soloed (unless intentionally monitoring).
• Check all input and output cables for secure connections and damage.
• Ensure the correct input source is selected and its gain is appropriately set.

Distorted Sound:

• Reduce the TRIM/GAIN control on the input channel.
• Check if the PEAK LED is constantly lit; if so, reduce the input level.
• Ensure the main output level is not too high, causing distortion in the connected amplifier/speakers.
• Check for damaged cables.

Phantom Power Not Working:

• Ensure the +48V PHANTOM switch is engaged for the specific channel.
• Verify that the microphone requires phantom power.
• Check the XLR cable for proper connection and damage.

Bluetooth Connection Issues:

• Ensure Bluetooth is enabled on both the mixer and your mobile device.
• Make sure the mixer is in pairing mode.
• Check for interference from other wireless devices.
• Try unpairing and re-pairing the devices.
