- True two-zone capability provides two independent outputs that each support volume/source selection remotes, EQ, tone controls, and paging/auxiliary routing options
- Opti-Voice paging equalizes the vocal frequency range for clear speech intelligibility while providing seamless transitions
- Dynamic EQ ensures full and balanced music at any volume level
- Independent Loudspeaker EQ per output enriches audio quality and simplifies connection to Bose Professional loudspeakers: FreeSpace 3 systems, FS3 subwoofer, FS2, FS4 and DesignMax DM2
- Dual remotes support optional volume/source selection for independent, or combined, zone control which eliminates the need for bulky, inefficient, and sound-altering 70/100V in-line volume controls
- Reliable 2 × 120 W Class-D amplification optimized for 70/100V high-impedance applications
- Intuitive feature setup enables the amplifier to be configured without a PC for remote, paging, auxiliary input/output and automatic standby options
- Auto-Standby feature allows the amplifier to consume less power when not in use
- Simplified front panel interface provides end users with tone, source selection and master volume controls as well as a connection to mobile sources via a 3.5 mm connector
- Remote muting allows the amplifier to be muted via a centralized control system
