Mixer Controls Overview
This section details the various controls and their functions on your XTUGA CT160 audio mixer.
Input Channels (1-16)
Each of the 16 input channels features dedicated controls for optimal sound shaping.
- Input Jacks (XLR/Line): Each channel is equipped with a combination jack that accepts both XLR (for microphones) and 6.35mm (1/4 inch) line-level inputs (for instruments or other audio devices).
- 48V Phantom Power: A dedicated switch for each channel activates +48V phantom power, essential for condenser microphones. Ensure phantom power is only used when required by your microphone.

- 3-Band EQ Adjustment (High, Mid, Low): These blue knobs allow you to fine-tune the high, mid, and low frequencies of each channel's audio signal for desired tonal characteristics.

- FX Send Control (Green Knobs): Adjusts the amount of signal sent from the channel to the internal digital effects processor.
- Pan Balance: Positions the channel's signal within the stereo field (left to right).
- Mute Button: Silences the individual channel's output.
- Channel Faders: Controls the overall volume level of each individual channel.
Master Section
The master section provides overall control and connectivity options.

- 7-Band Stereo Graphic Equalizer: Provides precise frequency adjustment for the main stereo output, allowing you to tailor the overall sound to your environment.
- Main Outputs (XLR & 6.35mm): Balanced XLR and unbalanced 6.35mm (1/4 inch) jacks for connecting to main speakers or power amplifiers.
- AUX Out: Additional auxiliary output for sending a mixed signal to external devices.
- Phone Output: A 6.35mm (1/4 inch) headphone jack with dedicated volume control for monitoring the mix.

- Main Faders (Red/Blue): Controls the overall volume of the main stereo output. The red faders control the left and right main outputs, while the blue fader controls the FX return level.
- Level Meters: LED indicators display the output level of the main mix, helping to prevent clipping and ensure optimal signal strength.
Operating Modes
Connecting External Devices
The CT160 mixer supports a wide array of external devices for various audio setups.
USB Playback and Recording
To play audio from a USB drive, insert the drive into the USB port. Use the MP3 player controls to navigate and play tracks. For computer recording, connect the mixer to your computer via a USB cable. The mixer will function as an audio interface, allowing you to record the stereo mix into your Digital Audio Workstation (DAW).
Bluetooth Streaming
Activate Bluetooth on your external device (e.g., smartphone, tablet). Press the 'MODE' button on the mixer's MP3 player section until 'BLUE' appears on the display. Search for 'BT-Speaker' on your device and pair. Audio from your device will now stream wirelessly through the mixer.
Digital Effects (DSP)
The CT160 features 99 built-in Digital Signal Processing (DSP) effects to enhance your audio. Use the 'PROGRAM' knob to select an effect and the 'FX SEND' knobs on individual channels to apply the effect to specific inputs. The blue fader in the master section controls the overall return level of the effects.
