The MU5891 is fitted with two dual
needle moving coil meters with PPM
scaling and ballistics. The left hand
meter has red / green needles for
displaying stereo audio. The right
hand meter has white / orange
needles, intended to display the M/S
content of the stereo signal fed.
This panel type is a standard 250mm
[9.84'] wide, the same as fader panels,
assignable panels and up-stand meter
panels.
As with all moving coil and 3rd party
meters, this panel does not access meter
data and requires an audio feed via the
console's rear interface.
If it is to be fed directly from the console,
this should be provisioned for in the
quantity of Hydra2 output ports ordered.
Moving coil meters can be fed with either
digital or analogue audio signals. The
inputs are mixed rather than switched
however so only one format should be fed
at any given time.
Connections
Audio is received via a female D25
connector on the console's rear interface
panel. This wires internally to a female
D25 on the back of the meter panel itself.
See the Surface Rear Connector Pin-outs
section for wiring detail.
The panel is powered via a single RJ45
connection fed from a POE switch
ancillary power port.
DIPswitchconfiguration
PCB mounted DIP switches provide
some configuration options for moving
coil meters. To access these switches,
the panel needs to be removed from the
control surface. Once removed, the drive
card for the meters is accessible from the
rear.
Level
A bank of 4 switches is used on each
audio leg to set the level to be displayed
on the meters at line-up. These are
adjusted to compensate for the meter
type and operating level. The table below
shows which bank of switches is used for
each audio channel.

Each bank of four switches should be set
as per the table below for the required
line-up level:
LEVEL SWITCH SETTINGS
L/RorM/S
The right hand meter can be set to display
left / right stereo, or M/S (mid/side /
sum/difference). DIP switch 5 should be
set accordingly as shown in the following
table. In M/S mode, the mono sum can
be a standard A+B-6, or it can be set to
A+B-3, using DIP switch 6.
