CONSUMER LEVEL VS PROFESSIONAL

LEVEL:

The purpose of the MB15b is to connect

consumer level equipment to professional

level equipment.

Consumer level signals typically come from

devices such as phones, tablets, CD play-

ers and DVD players. Professional level

signals are associated with devices found

in recording studios and sound reinforce-

ment systems like mixing boards, signal

processors, and their associated ampli-

ers.

- Broadcast

... Anywhere you need to convert consumer-level

audio to pro-level and/or vice-versa.
