BDI CDS-302 Audio Switcher


BDI CDS-302 Audio Switcher

The CDS-302 Automatic Composite Audio Switcher/DA is still the best base band FM stereo management product available. The unit accepts 2 base band inputs and distributes the selected input to 3 base band outputs. The unit incorporates our exclusive RBDS loop through feature for RBDS lock and distribution using only one RBDS generator.  The automatic feature allows for silence detected switchover in the event of an STL failure or processor lockup.

The CDS-302 accepts two composite baseband FM Stereo signals and distributes the selected input to up to three 50 ohm loads. Because the unit has an on board silence sensor it can automatically detect the loss of audio and switch to the alternate path. Other important features include our exclusive RBDS loop through feature. With the flip of a switch you can route the selected incoming baseband signal out to an RBDS
generator where the RBDS signal can be added and locked to the incoming composite audio where it is then routed back into the unit for application to the distribution amplifier. Make sure your newest processor and RBDS generator are always on whichever transmitter is on the air. With the CDS-302 you only need one RBDS generator - saving you money. Processors can lock up and when they do you can automatically or manually switch to a backup processor. Are you worried about signal integrity? The CDS-302 has a D.C. coupled signal path. This means your composite audio will arrive at the exciter without overshoot or phase delay. In addition the unit has the ability to accept balanced or unbalanced inputs with the flip of a switch.
Are your levels different between exciters? The CDS-302 has individual output level controls for level trimming to each exciter. Other uses include main/standby RBDS or SCA generator switching and distribution. The CDS-302 has a minimum useable bandwidth of 100 KHz.
