and 8) on the mixed impedance models (–MXZ). Use high impedance speakers for the
constant voltage models (–CV) and the six constant voltage outputs (1-6) of the mixed
impedance models (–MXZ). Observe proper polarity to avoid low frequency cancellation loss.
The sum of the tapped wattage for all speakers connected to a single output should not
exceed 100W
RMS
.
The total tapped wattage for all speakers connected to outputs 1-4 should not exceed
200W
RMS
. The total tapped power for all speakers connected to outputs 5-8 should not
exceed 200W
RMS
.
In normal operation, the DC voltage on the speaker output connectors is approximately
24VDC. Do not connect any speaker output to ground or to the amplifier chassis. Do not
connect speakers across speaker outputs. (Bridge mode is not supported.)

Dante™ Audio
MC850 amplifiers utilize Audinate’s Dante™ multi-channel digital media networking technology,
with near-zero latency and synchronization. Routing audio signals from Dante-enabled
transmitters to Dante-enabled receivers is accomplished via the
Dante Controller Software
available from
Audinate’s web site
. Please visit their web site for detailed information regarding
this technology, system and network configuration, troubleshooting, and other support. Note that
the MC850 Series amplifier supports the AES67 standard.
To enable the AES67 mode, click on the
AES67 Config tab in the Device View in Dante Controller.
6.1.2
RS-232 Control
An RS–232 port (settings: 9600 baud; 8 n 1) allows remote control of selected amplifier functions.
The RS-232 commands are defined in the following table. Each command string consists of 4 bytes
(except the SET ATTENUATION LEVEL command, which has 5 bytes), all transmitted in hex values.
Each command string starts with the start transmit code byte,0x02, and ends with the end
transmit code 0x03.
Note that the MC850 is a DCE device, that is, the transmit pin from the RS-232 controller should
connect to the transmit pin of the MC850, and similarly for the receive connection.
