Global Pad
Attenuates the signal going to the XLR direct box outputs by -20dB to prevent transformers saturation.
Auto On
Activates auto-switch mode. Will switch from inputs-A to inputs-B if the drone signal going to the gate disappears
Threshold
Sets the gate input sensitivity. If the drone signal drops below the set threshold the SW8 will switch from inputs-A to inputs-B.
Mute
Turns off the XLR outputs, leaving the balanced D-Sub output on for local monitoring.
Standby
Holds the auto-switching on inputs-A so that the SW8 does not switch to inputs-B while waiting for drone signal.
A-B Select
Front panel selector used to manually switch from inputs-A to inputs-B.
Alarm LED
Illuminates when the tone signal falls below the set threshold level.
Lift
Disconnects pin-1 on the XLR output to reduce noise caused by ground loops.
XLR Out
Balanced, low-Z direct box output is transformer isolated to eliminate hum and buzz caused by ground loops.
1/4" Inputs A & B
Two sets of eight balanced or unbalanced line-level inputs for the primary and backup systems.
D-Sub Output
Balanced line-level output is used to send the active input set (A or B) to the PA or local monitor system.
D-Sub Input
Balanced line-level A and B inputs are used to connect two multi-track playback units to the SW8.
Alt 1/8
Selects between channel 1 or channel 8 to receive the drone track for auto-switching.
Filter
Lets you use a binary signal such as SMPTE as a drone track by smoothing out the signal.
Auto-Switch Gate
Used to connect a drone signal directly to the auto-switching gate. Alternate option to using channels 1 or 8.
On A/B
Turns on remote A/B switching function when using the optional JR-2 footswitch. Disables the front panel A/B select.
JR-2 Link In / Out
Used to connect the optional JR-2 remote footswitch. Switch between A & B inputs and engage standby mode.
Contact Alarm
Internal relay can turn on a siren or becon when the drone signal drops below the set theshold.
15 VDC Supply
Provides power to the SW8. With cable clamp for safety.
