Beyerdynamic Opus Mix 31 User manual

APPLICATIONS
The Opus Mix 31 mini mixer has been developed to supply a maxi-
mum of 3 condenser microphones (e.g. Opus 86). It allows
operating the microphones in conjunction with a wireless micro-
phone system or a wired power supply unit.
The Opus Mix 31 is powered by a 9 V alkaline battery. The operating
time is approximately 70 hours.
The volume of the connected microphones can be controlled
with the appropriate volume controls to compensate different
levels between treble and bass with accordions or voice and
instrument.
The Opus Mix 31 provides a 4-pin mini XLR output (female) to
connect to a beltpack transmitter (e.g. TS 100 Mk II, TS 300 or
TS 800 (M) or a wired power supply unit (e.g. CV 18).
