ST MIXER XL is effectively an eight channel stereo mixer with a really good sounding headphone amplifier built in. It is designed to be the final output module of a larger system that you want to use with headphones and simultaneous recording via 1/8 inch stereo jack cable to a portable recorder.

The module consists of four mono channels with level, panning and aux send control, and two stereo channel with level control and separate inputs for left and right. The stereo PHONES and LINE OUT outputs also have level control. The AUX output is a mix of the aux sends from the four mono channels. The OUT 1 is a buffered direct out from channel one, to feed to a looper for instance.

ST MIXER XL is perfect for a larger system with up to four mono synth voices and a stereo effect. The headphone output can drive most headphones quite well and the line output is perfect for recording with a portable recorder or an audio interface.
