Tahoe Series 16

Balanced/Unbalanced Audio Connections

All audio sources from the routing switcher are balanced audio. Connect the balanced

audio to the balanced input of your destination device(s).

If this is a 2-channel system used for stereo audio, ensure that you keep the same phase

relationship. Connect the positive designated pin to the same relative pin on the

destination device of both channels.

To connect an unbalanced device to the switcher, first place a jumper between the

negative (-) and the ground on the switcher (jumper not included.) Then connect the

device positive (+) to positive (+) and shield to ground as shown in the graphic below.

For unbalanced sources, connect the unbalanced source to one side of the balanced

input and ground. The other input does not have to be grounded. Note, always use the

same side of the balanced input for stereo.

Audio Adjustments

There are no “user adjustable” audio gains. The circuit is designed for unity gain.

Audio Follow Video and Breakaway Audio Configurations

Video and Audio signals are switched by separate crosspoint modules. Audio can be

switched following the video or separately after the breakaway. Audio channels can be

configured to “breakaway” from each other (left and right, ect.).

J1 Connector

The connector labeled J1 on the back panel is used to connect other routing devices to

the router, such as an Audio frame or RS-422 machine control switcher.

Contact the factory for correct configuration before adding other devices that were not

part of your original configuration.
