To mix in the mic input signals from the MIC 1–2 INPUT (1) jacks, and output them from the monitor speakers, set the MONITOR OUT (g) mic mix switch to WITH MIC. NOTE

You can make selections with the MONITOR SE- LECT switches (r), and monitor signals before outputting them from the MAIN OUTPUTS 1–3 (UNBALANCED) (v) and MAIN OUTPUTS 1–3 (BALANCED) (c) jacks.

Monitored sounds are affected by the output equalizers.12 TASCAM MZ-223 Connecting headphones Connect headphones to the PHONES (s) jack (stan- dard stereo). You can monitor input channel pre-fader signals and signals before they are sent to the stereo output bus. Use the MONITOR SELECT (r) switches to select the outputs that you want to monitor. CAUTION Before connecting headphones, minimize the vol- ume with the PHONES VOLUME (a) knob. Failure to do so could result in a sudden loud noise that could harm hearing, for example. NOTE Sounds output from headphones are affected by the output equalizers. Connecting stereo amplifiers When connecting a stereo amplifier, connect it to the MAIN OUTPUTS 1–3 (UNBALANCED) (v) or MAIN OUTPUTS 1–3 (BALANCED) (c) jacks. TIP

When connecting 2 or more amplifier and speaker systems, including main and sub, main and mon- itoring, or front and rear combinations, using the MAIN OUTPUTS 1–3 (UNBALANCED) (f) and MAIN OUTPUTS 1–3 (BALANCED) (c) jacks could be convenient. Moreover, the outputs of the jacks are independent and have their own dedicated output knobs, so you can set the output levels separately with this unit.

By connecting a recorder to MONITOR OUT (x) jacks, the signal output to amplifier/speaker sys- tems can be recorded. Turning the power on and off CAUTION

Turn down the volume of the sound system con- nected to the unit before starting up or shutting down the unit.
