The Start Control Section

The operation of the start control depends on the internal jumper setting. It can be controlled by the fader, the cut switch and an additional Start switch. There are two totally independent control remote control relays that are switched by the input select. This makes it possible to install separate remote controls for two devices.

The start system is primarily controlled by the fader swich. When the fader is open, start is active. If the channels is muted by either the local CUT switch or a cut groups, the start is disabled. The additional START switch operates in parallel.

This means in detail:

Start is only enabled if the channel is not muted. When mute is not active, opening the fader or pressing the start switch with fader closed causes Start. While the start switch always toggles the actual state, closing the fader will only cause stop. If stop mode was active before the fader is closed, nothing happens. With static mode, the start relay is closed with 'start' and the stop relay is closed with 'stop'. With pulsed mode, the start relay is on for 0.2 seconds when start is enabled and the stop relay is on for 0.2 seconds when start is disabled. The state of the fader switch and of the start system are displayed by two, independend LED's.

Each control section has two relays and can be used in static or pulsed mode. In static mode, the particular start relay is on with 'start active'. With pulsed mode,


The connector section uses 2 XLR connectors for the stereo input one and two 1/4" balanced, TRS jacks for the stereo input two. All connectors are gold plate, brand Neutrik.
