System Connections - Acurus Muse Operating Manual And Installer Manual

system connections

The MUSE pre-amp processor is designed for simple,
reliable connections in a variety of system configurations.
Following the guidelines below will ensure optimal
performance from your MUSE pre-amp processor.
IMPORTANT NOTE: Make system connections
with AC power off.
HDMI Audio/Video Source Inputs
You may connect up to seven HDMI source devices to the
MUSE HDMI inputs i1 – i7. All HDMI inputs support 4K HDR
and HDCP2.2 provided that high quality HDMI cables are
used. Avoid using excessively long cables (longer than 3
meters), coiling or bunching up of cables.
HDMI Display Output
Connect the video display (TV or projector) to output 2
which is the full HDMI 2.0b output. Use of output 1 should
generally be avoided as the video system is limited to HDMI
1.4 on this output. Be sure to use high-speed HDMI cabling
to avoid dropouts and loss of audio or video. For runs longer
than around 3 meters, use of DPL-certified active optical
HDMI cable is highly recommended.
Coax Digital Audio Source Inputs
Use high quality RCA interconnects to connect up to two
coax digital audio source devices to MUSE inputs i11– I12.
Avoid coiling or bunching up of cables. Be sure RCA cables
are fully inserted into MUSE input jacks in order to avoid
dropouts or other digital signal integrity problems.
Optical Digital Audio Source Inputs
Use high quality Toslink optical interconnects to connect up
to two optical digital audio source devices to MUSE inputs i9
– i10. To prevent signal integrity problems or permanent
damage to optical cables, avoid tight turns or bundling.
Stereo (RCA) Audio Source Inputs
Use high quality RCA interconnects to connect up to two
analog audio source devices to MUSE stereo audio inputs
i13 – i14. Avoid coiling or bunching up of cables. Be sure
RCA cables are fully inserted into MUSE input jacks in order
to avoid hum and other analog signal integrity problems.
Balanced XLR Audio Pre-amp Outputs
Use high quality XLR interconnects to connect to external
power amplifiers, subwoofers and/or powered loudspeakers.
XLR to RCA adaptors may be used with pin2 hot and pin 1
signal ground. Pin 3 may be shorted to pin 1 or left open.
Balanced XLR AUX Outputs
Use the Acurus-sourced DB-9 to XLR (x4) Tetra cable to
connect to power amplifiers, subwoofers and/or powered
loudspeakers in layouts requiring more than the built-in 12
chassis mounted XLR outputs.

Coax Digital Audio Downmix Output
Use high quality RCA interconnects to connect the MUSE
coax digital downmix output to an external zone amplifier or
LFE seat vibration unit. Be sure RCA cables are fully
inserted into MUSE input jacks in order to avoid dropouts or
other digital signal integrity problems.
Optical Digital Audio Downmix Output
Use high quality Toslink optical interconnects to connect the
MUSE coax digital downmix output to an external zone
amplifier or LFE seat vibration unit. To prevent signal
integrity problems or permanent damage to optical cables,
avoid tight turns or bundling.
Trigger In and Out Control
To enable automatic power on/standby control of the MUSE
from an external control system or power conditioner,
connect a trigger cable from the trigger out of the controlling
device to the 3.5mm 12V trigger input on the MUSE. The
MUSE trigger input jack is wired with its tip active and will
accept either a stereo or mono plug.
Similarly, to enable the MUSE to automatically control
external power amplifiers and/or send a power signal to an
external control system, connect one of the two trigger
outputs t1 – t2 to the device to be controlled via a trigger
cable for each slave device.
USB Power
Connect up to two USB-powered streaming media devices
or active HDMI cables to this pair of 5V USB power outputs.
Control Networks
Ethernet:
Ethernet Control (E2C), connect the Ethernet port to a
10/100 or faster home network router or switch port via a
standard CAT 5e or newer Ethernet cable. The network
activity indicators near the Ethernet jack illuminates green
when the MUSE is powered on and an active network
connection is detected.
This port may also be directly connected to a system
controller utilizing Ethernet command protocols (see section
"Ethernet Command Protocol".
RS-232:
system controller or computer using a 9-pin RS-232 serial
cable for full bi-directional control and monitoring of the unit.
Mains (AC) Power
The MUSE is equipped with a high-quality 14 gauge, 3-
conductor power cord. Plug this cord into the back of the
pre-amp processor and then into a nearby AC outlet. Avoid
using any extension cords or plugging into other
components with rear-panel switched outlets.
