The 3D Active Ambient system has two operating modes - "Perform" and "Full Ambient" - selected by toggling the 2-position Mode switch located on top of the bodypack mixer. During the show, simply flip the toggle switch to change between Perform mode (used while playing) and Full Ambient mode (used between songs) as desired.

In this mode, your direct IEM mix is heard normally, with sound from the earphone mics added at a level determined by the setting of the "Ambient Background" knob (X), an 8-position rotary control found inside the mixer, just above the battery.

The maximum ambience level is unity gain (control position "7" on the control knob). The knob reduces ambience in 4dB steps, down to -24 dB (control position "1"). Setting the knob to "0" turns off ambience completely, leaving only the IEM mix - like a conventional personal monitor system. Typically, the Ambient Background is set to a reduced level (below unity gain).

Volume for your monitor mix in Perform Mode is set externally as follows:

• 3DAA System (3D-M Mixer) - Adjust the output level control on your wireless IEM receiver.
• 3DHW System (3D-L Mixer) - Set monitor level using the "MON" knob on top of the 3D-L Mixer.

This mode is generally used between songs, to converse with other band members and hear the audience. The ambient audio from the earphone microphones is presented at unity gain (full natural volume), while the IEM mix is automatically reduced. In Full Ambient mode, you can hear the sounds around you normally, with full directionality - left/right, front/back, up/down - just as if you were not wearing earphones. The system circuitry detects whether the IEM mix is too loud and dynamically reduces the monitor level to allow conversation.

REMEMBER:

• In Perform Mode, the level of the direct monitor mix is set using the volume control on your IEM receiver, while the level of stage ambience from the 3D earphone mics is set using the Ambient Background volume control inside the 3D bodypack mixer.
• In Full Ambient Mode, there are no adjustments. Ambient audio is heard at unity gain, while the 3D system automatically reduces the monitor volume.
