DESCRIPTION
The IN3546R is a 6 input / 1 output stereo audio switcher designed to work in tandem with the INLINE
IN3500 / IN3600 Series switchers. When input channels are selected on the RGB switcher, the
IN3546R will automatically switch to the corresponding stereo audio input, adding audio-follow-video
capabilities to the RGB switcher. The IN3546R receives both power and switching commands from the
attached IN3500 Series RGB switcher via a custom 15 pin control cable which is provided with each
unit. While the IN3546R was designed to work in conjunction with an IN3500 / IN3600 Series RGB
video switcher, it may also be used as a free standing stereo audio switcher if the appropriate power and
contact closure signals are applied to the 15 pin control port (see Using the IN3546R in Stand-Alone
Configuration).
Audio signals are routed passively through the IN3546R and the unit will accept any audio signal input
level. All input and output connectors are terminated with RCA female jacks. Separate left and right
attenuation potentiometers are provided for each input channel, allowing individual adjustment of output
voltage over a range from 100% to 5% of input voltage.
COMPATIBILITY
The IN3546R will work with the following INLINE models:
IN3504 / IN3506
