Talkbox Pro Bedrock BTB65

High-Output STIPA for Acoustic Consultants BTB115

The BTB115 Advanced Talkbox is the professional choice for acoustic consultants and large venue testing. When standard talkboxes can’t deliver enough level, the BTB115 steps up with 95 dB SPL output and 12+ hour battery life.

Built for Acoustic Consultants

Professional consultants need reliable equipment that works in challenging environments. The BTB115’s higher output overcomes high ambient noise in stadiums, airports, industrial facilities, and tunnel systems. The extended 12+ hour battery life means you complete multi-day surveys without worrying about power.
