Description

The Bel BCR-A4-4OB is a high quality stereo audio confidence monitor for permanent installation in broadcast control suites. The unit is very compact, occupying only 200 mm of rack depth in 1U, so is ideal for use in OB vehicles of all types.

The audio quality is exceptionally good, due largely to the use of four loudspeakers – separate LF and MF/LF drivers per channel – and 100 dB SPL can be generated at 0.6 m. There is a front panel headphone socket which mutes the internal speakers. Monitoring volume is adjustable on the front panel.

The BCR-A4-4 OB can accept both analogue and digital audio signals: the rear panel has eight balanced line level inputs on a Dsub socket and four AES3 inputs on BNC sockets. The AES3 inputs accept all sample rates from 32 kHz to 96 kHz, and digital lock is confirmed by per-input front panel LEDs at all times.

The stereo pair to be monitored is selected with a front panel rotary switch. The unit may be configured for two-channel operation – as opposed to stereo – if wished, by moving internal jumpers. In this case, the front panel level controls change from stereo level plus balance to separate L and R controls. The selected input signal is always available as a stereo 2ch pair of balanced analogue outputs at line level on rear panel XLR connectors.

As well as being monitored for audio quality, the level of the selected signal is displayed on two 10-segment LED bargraph meters. The phase relationship of the input pair is checked, and if a sustained out of phase condition is detected, a red LED on the front panel illuminates.

Like all Bel broadcast products, the unit is built to a very high mechanical standard in a stainless steel enclosure. Warranty is for 3 years.
