Can I connect the Master Outputs from my T4S ToneMatch mixer or T8S ToneMatch mixer to RCA phono inputs on a mixer?

Environment

The house system at a gig has only RCA phono inputs.


Resolution

RCA phono inputs are usually consumer level inputs: -10dBv. Your T4S outputs are pro audio level: +4dBu. The outputs of the T4S will likely be 11.79 dB higher than the RCA phono inputs were designed to handle. This may still all work, but you may have to keep the T4S Master Output lower than usual to avoid distortion.

See: -10dBv and +4dBu voltage levels
