The Ace is equipped with eight line inputs, and four microphone inputs (channel 1...4) with, for each microphone, a rear gain trimmer, an internal two-band equalizer and phantom power that can be turned off.
Each microphone channel has a talk-over circuit to enhance speech intelligibility. This circuit, activated by the microphone signal (voice-activated), ensures that this signal overrides all other signals.
The talk-over switching of each microphone channel can be enabled,- and disabled with an internal sweater. The talk-over function can be disabled with the talk-over switch on the front panel. The talk-over threshold can be adjusted internally.
The Ace has two output zones. Zone 1 has a three-band equalizer, and volume control. This zone is equipped with balanced and unbalanced outputs. Zone 2 has only volume control and unbalanced outputs. This zone can be set by a switch to follow the equalizer settings of zone 1.
