The CMP-300 Composite Mixer Distribution
The solution for not enough inputs or outputs ...
The CMP-300 was developed by our engineers to solve the problem of not having enough inputs or
outputs for base band signals. Many stations are adding subcarriers and RBDS services and have
exciters without the proper number of inputs. The CMP-300 has three balanced or unbalanced inputs
that can easily mix composite stereo, subcarrier and/or RBDS Signals. The unit has a three output
distribution amplifier so that the mixed signals can be distributed to up to three exciters or STLs.
Each input is rear panel switchable for balanced or unbalanced operation. Each output is capable of
driving a 50 ohm load as far away as 100 feet from the unit because we incorporated a heavy duty
line driver in the design. The front panel has provision for level control of inputs and outputs giving
you complete flexibility.
BDI has been a leader in producing composite audio products for many years and the CMP-300 is
a third generation development that was designed to help broadcasters meet the demands of today’s
broadcasting environment while keeping budgets intact. Call us today for applications assistance or
