Overview

The ARC-2 and ARC-2i, known together

as the Menu ARCs, are menu-driven

remote controls for Symetrix DSPs.

Tap into the full power of your system with

twenty-four (24) menus with up to sixteen

(16) items each that can be used to address

multiple basic functions or initiate complex

logic-based control events: gain, preset

triggering, source selection, room combining

andmore.The8-character

backlit display supports up

to thirty-one (31) scrolling

characters, providing

instant user feedback

for control assignments,

default settings, and

actions. The three buttons

help you navigate menus,

raise or lower values,

and enable or disable

the remote control. All

control assignments,

including item labeling,

parameter limits and

ﬁrmware version upgrades

are handled by software

included with Symetrix

DSP hardware. Power,

control, and a single channel of ARC Audio

are connected via RJ-45 inputs or screw-

type barrier strips. Intuitive Navigation:

Pressing the menu button navigates through

the menu names. The menu button also

acts as a preset trigger when a preset list

is scrolled. The up/down arrow buttons

adjust parameter settings and scroll through

preset lists. Holding the menu button and

using the up/down arrow keys moves you

forward or backward through the menus.

Programmable Setup: The wall panel’s

behavior is programmable as well. Menu

brightness in “active” and “inactive” states

can be set independently, so the display will

“sleep” in light-sensitive environments like

theaters.

If the Menu ARC goes idle, it can

scroll a message and return to the top of its

menu tree. Upper and lower parameter limits

help contain the range of adjustment and a

button press lockout will prevent tampering

by curious but unauthorized ﬁngers. The

ARC-2 features an aluminum faceplate and

includes a power supply while the ARC-

Remote ARCs

TheARCportsdistributepowerandRS-485datatooneor

more ARCs arranged in one or more chains over standard

CAT5 cable. Most Symetrix products with an ARC port

can power from two (2) to ten (10) ARCs. (Please see the

individual products’ documentation for speciﬁc details.)

WARNING: The RJ-45 connectors labeled “ARC”

are only for use with the ARC series of remotes.

DO NOT plug the ARC connectors on Symetrix

products into any RJ-45 connector labeled

“SYMLINK”,“ETHERNET”or“COBRANET.The“ARC”RJ-

45 connectors on Symetrix products can carry anywhere

from 6 to 24 VDC which can damage SymLink, Ethernet and

CobraNet circuitry.

ARC Network Design

The ARC can be powered two ways: (1) over CAT5 via the

RJ-45 “ARC” port on ARC-enabled Symetrix products, or (2)

by local 6 to 24 VDC power supplied to the ARC’s terminal

block connections.

The ARC’s power requirements vary depending on the

voltage supplied to it. At 15 VDC, it uses approximately

115 mA, while at 6 VDC it uses approximately 300 mA

maximum. As the voltage goes from 15 to 6 VDC, the

current requirement increases accordingly.

ARCs can be daisy-chained and fed power over this daisy-

chain from the ARC port. However, as the length of the

cable increases, so does the resistive line loss, which lowers

the voltage available at each subsequent ARC. The actual

power drain on each output from an ARC port can vary

substantially depending on the number of ARCs and the

distance each of them is separated by. In order to assist

with system design, Symetrix has available a Microsoft Excel

spreadsheet that can help a system designer determine

power requirements based upon cable length, number of

ARCs and the power supply to be used. This spreadsheet

can be downloaded from the Symetrix Technical Support

pages at: http://www.symetrix.co.

The following table gives some indication of cabling

limitations, based on DC power only (the following table is

only relevant for the RJ-45 ARC port when powering a

Menu ARC from the ARC-PS): minimum stated distances

Disclaimer: From time to time we test the compatibility of

our own products with those of third parties. While we are

happy to share with our customers the results of our own

studies as well as other possibly unsubstantiated information

regarding these third party products, it is the policy of

Symetrix, Inc. to neither endorse, recommend nor support

The responsibility of choosing third party products which

are compatible with Symetrix products rests solely with the

qualiﬁed contractor, consultant or system designer.

WARNING: When designing a system, one must

be careful not to double power any ARCs. If all

pins on the CAT5 connections are used, power

can travel over the CAT5 cable and reach any ARC on that

particular chain. So, power over CAT5 could potentially

come from the originating ARC port or from an ARC that is

powered locally and then daisy chained via CAT5 to other

ARCs. In general, it is recommended to use only one type of

connector on the ARCs, either the RJ-45s (with CAT5 cable)

or the terminal blocks

Audio to transport audio signals back to a Symetrix rack

mount device.

Note 1: The original Menu ARC remote (simply named

“ARC”) does not support ARC Audio lines and will ground

the audio lines if connected.

Note 2: To avoid the possible grounding, mixing, or shorting

of the ARC Audio lines, it is recommended to home run any

ARC devices making use of the ARC Audio lines so that only

one ARC device is on each chain.

Limits of ARC Audio

ARC Audio is a simple analog audio signal travelling the

samecableastheRS-485dataandpower.Assuch,the

usual audio signal cautions apply. Avoid running parallel to

other power lines or near any other sources of EMI or RFI.

Most CAT5 is unshielded and is susceptible to interference

and noise. We provide here the following information on ARC

Audio’s performance and limitations:

Line-level Balanced Audio:

Professional line level balanced signals can also be sent over

up to approximately 1500 feet of CAT5 without signiﬁcant

degradation.

All unbalanced signals should be avoided completely.

Mic-level Audio:

Unbuffered condenser or dynamic microphones should

generally be avoided, though it may be possible to achieve

decent quality with cable runs of less than 50 feet using a

fairly hot microphone level with a

noise gate or expander in to clean up the signal. This

technique does not provide much ﬂexibility within the system

design, and therefore is not recommended.

Frequency response:

Frequency response can roll-off due to the capacitance of

a long cable run. The amount of roll-off is highly dependent

on source impedance (the output impedance of what is

supplying the signal). Most pro audio devices have low

output impedances (200 Ohms or less) and do not suffer

signicantroll-off(approximately-1dBat20kHzwith1500

feet of CAT5). A device with a 600 Ohm output impedance

couldcausesomeaudibleroll-off(-3dBat10kHz),but

should be of sufﬁcient quality for speech signals.

Data Noise:

With an unbuffered mic and long cables, data noise may

be audible as a “motorboat” sound. Experimenting with

RS-485terminationandbaudratemayimprovethesound

somewhat.
