INSTALLATION

GUIDE

STEP ONE ➧

Determine appropriate location for unit.

NOTE: The SM1 requires a minimum of 11 in.

(280 mm) depth, 9.625 in. (245 mm) width, and

3.25 in. (83 mm) height. Space must be provided

both above and below the unit for proper venti-

lation. The feet will provide 0.2 in. (5 mm) below

the unit. At least 1.75 in. (45 mm) is recommend-

ed above the unit.

STEP TWO

NOTE: Verify that the unit’s power switch is

in the off (out) position.

Using the included power cord, con-

nect unit to an appropriate power

source (85-240 VAC, 50/60 Hz).

STEP THREE ➧

Plug CommStar speaker system into the unit’s

DPL To Speakers connector.

NOTE: A maximum of 8 speakers can be connected

to each power source unit. Use only standard wiring

CAT5E cable (no crossover wiring), rated VW-1. For

DPL connector pin assignment, see CommStar Tech

Notes, Figure 2.

TOOLS RECOMMENDED FOR INSTALLATION

• A #2 cross-tip screwdriver

(or a powered screwdriver with a #2 cross-tip bit – not shown).

• A mini standard blade screwdriver

STEP FOUR

Connect audio outputs from CD players, Satellite Radio, DVD players, portable music

players, etc. to the RCA inputs on the back panel and/or front panel of the unit

(and/or the stereo mini-jack on the unit’s front panel).

NOTE: As viewed from the back, the leftmost, vertical, red-white RCA pair can accept a higher audio

level than the unit’s other RCA or stereo mini-jack inputs.

STEP FIVE ➧

Depress the front panel power

switch until it clicks, turning the

unit on.

STEP SIX

Adjust front panel control for the

desired music level.

NOTE: It may be necessary to adjust

source to match levels.

STEP SEVEN ➧

NOTE: If not connecting a microphone directly

to the unit, skip to Step Twelve.

Verify that the back panel Microphone

Level control is fully counter-clockwise

(minimum level).

STEP EIGHT ➧

Using either the XLR (large photo) or

the euro-block (inset photo) Microphone

Input connectors, plug in the desired

paging microphone.

NOTE: If pre-announcement alert tone is

required, connect switch to the two Chime

terminals of the euro-block Microphone Input

connector. If using a condenser microphone

that requires Phantom Power, see CommStar

Tech Notes Figure 1, Phantom Power Supply

section.

STEP NINE

With the back panel Microphone Level

control fully counter-clockwise (minimum

level), speak forcefully into the paging

microphone and verify that the

Mic Clip

LED is off (or rarely turns on).

NOTE: If the Mic Clip LED is on frequently, internal

gain reduction may be required (CommStar Tech

Notes Figure 1, Microphone Preamp Gain section).

STEP TEN ➧

Still speaking forcefully into the

paging microphone, rotate the rear

panel Microphone Level control

clockwise until the desired paging

output level is achieved from the

sound system.

NOTE: If attenuation of music during a page is

not desired, see CommStar Tech Notes Figure 1,

Background Music Attenuation section.

Mic Clip LED

STEP ELEVEN

Speaking normally into the

paging microphone, adjust the

Microphone’s Low frequency

(large photo) and High frequen

cy (inset photo) controls for the

desired voice contour or timbre.

STEP TWELVE ➧

If using a professional mixer, con-

nect its mono analog output to the

euroblock Balanced line Input

NOTE: If music-enhanced signal process-

ing is desired for the Balanced Input, see

CommStar Tech Notes Figure 1, Balanced

Input Signal Processing section.

OPTION 1

Use this unit’s Link In jack to connect

a professional mixer (or other source)

with an AES/EBU output. For Link In

details, see CommStar Tech Notes, Figure 5.

NOTE: The last speaker of one CommStar

system may be connected to the Link In

jack of another SM1 (or a C1), allowing for

system expansion.

OPTION 2 ➧

Other systems with an AES/EBU in-

put may be connected to this unit’s

Link Out jack. For Link Out connector

pin assignment, see CommStar Tech Notes,

Figure 4.

NOTE: This unit’s Link Out may be con-

nected to the Link In of another SM1 (or a

C1), allowing for system expansion.

OPTION 3

If remote volume control is re-

quired, only use CommStar model

RVC, and connect it to the unit’s

Remote Volume Control

jack.

For Remote Volume Control connec-

tor pin assignment, see CommStar Tech

Notes, Figure 3.
