Answer:
The SBS-20 uses 100V line matching distribution to connect remote classroom talkback speakers and pairs with external PA power amplifiers. The required amplifier capacity depends on the aggregate quantity and wattage of the connected speakers.
The Hitune Bass SBS-20 is built for commercial distributed sound architecture:
- Speaker Topology: Uses 100V line matching distribution to deliver signals over long cable runs to remote classroom talkback speakers without significant line loss.
- External Amplification: Connects to external public address power amplifiers; the wattage of the amplifier is sized according to the total count and power ratings of the classroom speakers in the installation.
- Two-Way Return Signal: Receives return talkback audio from classroom substations back through the line network into the console's integrated monitor speaker.
