Optional input board for secondary input – SD-1:
→♪ Transformer balanced microphone level signal of 5 - 10 mV.
The Messenger is equipped with an RS485 data-network connection, which allows
remote system set-up and control of all parameters available through the M-Control
software for Windows®. Each addressable loop device gets a unique I.D. number for
quick FIR/Lobe downloads. I.D.-numbers are chosen between 1 and 32.
A two core communication link is used to connect an RS485 serial link to up to 32
Messengers using the DATA-RS485 input and slave-output.
NOTE: - An end-of-line resistor of 120 ohm should be applied to the last Messenger
connected in the data-ring.
The Ambient-Noise-Following option is supplied in the software and needs the
hardware module SD-1 and an ambient-noise microphone. The SD – 1 is equipped
with a pre-amplifier with phantom power and uses the secondary input of the
Messenger.
The ambient temperature for the Messenger XL should not exceed 40°C. If higher
temperatures are expected, precaution should be taken to avoid this by means of
installing extra forced ventilation within the Messenger. Alternatively a Messenger
XL/WP can be ordered which has the electronics externally installed in box. This unit
must be placed in a conditioned room.
