Teach seamlessly with Pro Digital

FrontRow Pro Digital is the leading choice of schools for
multi-speaker classroom audio. The reason? It’s supremely
good at delivering on the core mission of sound in the classroom:
speech clarity.

Pro Digital features OptiVoice™, a patented algorithm that
makes speech easier to understand for test-taking, directions,
and ESL instruction. OptiVoice strengthens fragile consonant
sounds with a digital 12-band equalizer in a single switch.

Pro Digital incorporates the Adapto™ digital algorithm that
checks hundreds of times per second for acoustic feedback —
the harsh squealing that can plague analog mic systems —
so teachers can move freely without noisy disruptions, making
it easier to teach calmly and clearly.

With the CMBT Bluetooth® audio receiver, teachers can
wirelessly play audio for the entire class through their Pro
Digital system. Now instructors can conveniently use audio
from phones, TVs, tablets and other Bluetooth-enabled

devices to support their lessons.
