The provided document is a user manual for the the t.mix xmix 802 USB mixer.

Here's a description of the device based on the manual:

The the t.mix xmix 802 USB mixer is an 8-channel audio mixer designed for amplification, mixing, and playback of signals from musical instruments and microphones. It features a built-in power supply and a USB port for digital audio integration.

Function Description:

The mixer allows users to combine multiple audio input signals, adjust their levels, equalization, and panning, and route them to various outputs. It supports both mono and stereo input channels, with dedicated controls for each. The USB port enables the mixer to function as an audio interface, allowing digital audio signals to be fed in or the sum signal to be output digitally.

Key Features:

• 8-channel mixer: Provides ample inputs for various setups.
• 4 mono channels (MIC, line): Each mono channel includes a balanced XLR input for microphones and a 1/4" phone input for line-level audio sources (e.g., keyboards, drum modules). These channels offer 3-band EQ (treble, mids, bass), switchable 48V phantom power, and a low-cut filter.
• 2 stereo channels: These channels feature balance control for stereo imaging.
• AUX control per channel: A dedicated AUX control allows users to send a portion of the channel signal to the [AUX SEND] output, useful for creating monitor mixes. This control is switchable between PRE (unaffected by channel fader) and POST (subject to channel fader).
• FX control per channel: A rotary control to send a portion of the channel signal to the [FX SEND] output for external effects processing.
• Master outputs: The main stereo output is available via two XLR connectors and two 1/4" phone sockets.
• CTRL room output: A stereo 1/4" phone socket for connecting control room monitors.
• Additional RCA connections: Stereo RCA inputs ([STEREO IN]) for connecting stereo sources and stereo RCA outputs ([REC OUT]) for connecting recording devices.
• Headphones output: A separately controllable 1/4" phone socket for stereo headphones, adjustable together with the Control room output.
• 48V phantom power: Globally switchable for condenser microphones.
• USB port: For feeding in digital audio signals or for digital output of the sum signal, unaffected by the master faders.
• PFL (Pre-Fader Listen) function: Allows monitoring of individual channel signals before the fader and internal effects, useful for setting input levels. An LED indicates when PFL is active.
• Peak indicators: LEDs on each channel and the master section to indicate signal overload, prompting users to reduce input or output levels.
• Built-in power supply: Simplifies setup by eliminating the need for an external power adapter.

Important Technical Specifications:

• Max. output level (1% THD @ 1 kHz):
  • MAIN OUTPUT (XLR & 1/4" phone, balanced): +26 dBu ± 1 dBu
