Frequently asked questions
Can I use the ZC-BOB for audio signal routing?
No. The ZC-BOB is designed exclusively for DC control voltages from zone controllers using CAT5 cabling and RJ-45 connections. It is not intended for audio signals.
Will the PB48 work for control voltage aggregation in a multi-zone system?
No. The PB48 uses 1/4-inch phone jacks for balanced or unbalanced audio signals and is designed for audio patch routing, not control-voltage consolidation.
Which product requires a power supply?
Neither product requires external power. Both are passive devices: the ZC-BOB transmits control voltage directly through RJ-45 connections, and the PB48 provides transparent audio paths without amplification or processing.
What skill level is needed to install each?
The ZC-BOB suits system installers working with distributed control architecture. The PB48 is described as suitable for intermediate, advanced, and professional users managing studio, live, or recording setups.
