Bella 22 MKII is a 2 buss summing matrix confidence monitor designed for outside broadcast trucks, studios, theatre and professional audio applications. It is perfect for easy and cost effective monitoring of multiple network audio sources, ideal for busy production environments and perfect for monitoring multiple network intercom & programme feeds.

The 2 front panel loudspeakers are driven from a DSP to compensate for their size. The result is surprisingly good, with clear crisp vocals and highly intelligible reproduction of wider band audio sources. They are driven from a class D amplifier and have more than sufficient output level for most environments.

Robust proven construction techniques, simple reliable interface and excellent specification will help make your technician’s life hassle free, whilst the low cost and long asset life will keep the accountant satisfied.

Available in two versions:
Bella 22 - Dante/AES67 network version
Bella 22/R - Ravenna/AES67 network version
