2.3 Hx2 Internal Mix Minus

The two hybrids in the Hx2 unit may be configured so that a single mix-minus feed may be used for both hybrids, with each hybrid’s output fed into the other’s input internally at unity gain (so that the callers can hear each other) and sums each with the audio from the consoles mix-minus output. Only the SEND IN #1 input is used to feed both hybrids.

Both hybrid outputs still function independently. The two hybrid outputs are NOT summed together, so you should provide a fader for each hybrid. The consoles mix-minus must be configured so that no hybrid’s output gets sent to its own input.

The figure above illustrates which signals are combined together inside the Digital Signal

Processor and routed to each connector when the Hx2 internal mix-minus feature is enabled.

Use this option if you only have a single mix-minus available from your console and you wish to use both hybrids to conference callers on the air. You’ll still need a fader for each hybrid output.

Bit #6 in the ‘OPTIONS’ DIP switch bank controls the mix-minus feature. The internal mixminus feature is enabled when the switch is ON. The default factory setting is OFF - Disabled.
