Wolff Audio Collaborator

Wolff Audio Collaborator – a 4-channel reference headphone amplifier system built like a tank, featuring a unique "HearMe" foldback microphone for seamless communication and room monitoring.

The Collaborator is designed to foster efficient teamwork in the studio. Its rugged steel chassis houses four independent high-definition headphone amplifiers, each with its own level control. A standout feature is the built-in "HearMe" foldback microphone, allowing musicians to hear each other and communicate without removing their headphones. With adjustable mic gain and foldback level, each artist can blend in the perfect amount of room sound (e.g., a drummer can bleed in natural room ambience). The mic can be toggled on and off via a standard footswitch.

The system is scalable – a rear TRS headphone level input allows multiple Collaborator units to be daisy-chained, making it perfect for choirs or horn sections. Power is delivered by an external 5-pin supply (the same used for Wolff's 500 series), ensuring massive headroom and punch. Main audio inputs are professional XLRs handling +4 dBu line-level signals.
