EUROCOM SL4208S

Connections

Note: Before terminating any wire,

turn all equipment o and disconnect

the AC power.

SL4208S is equipped with a 5-position

terminal strip to access the transformer for

both 70 V and 100 V operation.

NOTE: The same terminals are used for

both70 V and 100 V connections.

However,wattage doubles when using a

100V amplier as opposed to a 70 V

amplier. When using a 100 V amplier,

thesubwoofer’s lowest wattage rating

(10W) is unavailable.

Add up the total transformer taps of all the

loudspeakers to be powered, andensure

the power requirement does not exceed

80% of the HI-Z amplier’s available power

output. Alwaysfactor 20% for peak output

headroom andlineloss.

Examples

Diagrams for both of these examples can

be found in the Hookup section of this

QuickStart Guide.

NOTE: For best results, set your satellite

speakers into High Pass (HP) mode.

SL4208S parallel with full-range

speakers from single 70 V / 100 V

amplier channel

As shown in the rst system example,

asimple daisy chain connection between the

SL4208S and other satellite speakers in

HighPass (HP) mode will yield good results.

TheSL4208S can be added anywhere

throughout the distributed speaker line.

TheSL4208S’ built-in low pass lter will roll

o high frequencies and eliminate

“localization” of the subwoofer.

System requires at least a 70 W amplier.

Total Power Calculation

4 x Satellite Speakers @ 4 W / 70 V 16 W

1 x SL4208S @ 40 W / 70 V 40 W

Total Wattage 56 W

Total Wattage x 1.2 (20% Headroom) 67.2 W

SL4208S powered from a dedicated

70V/ 100 V amplier

The second system example shows a system

with the subwoofer and satellite speakers

connected to their own dedicated amplier

channels. Using dedicated amplier

channels will provide additional balance

control between subwoofer and satellite

speakers in High Pass (HP) mode, as well as

improved overall dynamic range.

System requires at least a

240Wamplier.

Wire Gauge Suggestions

For cable lengths up to 300 feet

(appr.92meters), use 16/2 twisted pair,

stranded speaker cable. For cable lengths

ranging from 300 to 600 feet (appr.92to

183 meters), use 14/2 twisted pair,

strandedspeaker cable. (Use plenum-rated

cable if required by local codes or AHJs.)

Rigging Instructions

Location Considerations for

theSL4208S

Additional output can be attained by

placing the SL4208S near adjacent at

surfaces (nearwalls, ceilings, or in corners).

“Boundary loading” into a corner near

the ceiling will provide optimum results.

Avoid placing the SL4208S in a “free space”

environment with no coupling surfaces.

Mounting

The SL4208S is designed to be shelf or oor

mounted. The rubber isolation feet may be

easily relocated to accommodate horizontal

or vertical orientation.

Aerial Suspension

Alternatively, the SL4208S may be

suspended using threaded rod and

structural strut in open

ceilingcongurations.

WARNING! Suspension of

overhead speaker systems

requires training and expertise.

Improper rigging of a suspended speaker

may result in injury, death, equipment

damage, and legal liability. Installation

must be carried out by fully qualied

installers, inaccordance with all the

required safety codes and standards that

are applied at the place of installation.

5:1design factor is the generally

accepteddesign standard; however,

legalrequirements for suspension vary by

municipality. Please consult your local

safety standards oce before installing any

product. If you lack the skills, training,

andproper ancillary equipment to suspend

a speaker system, do not attempt to do so.

ONLY LOAD-RATED &

CERTIFIED HARDWARE

SHOULD BE USED FOR

INSTALLATION OF THIS PRODUCT.

Loudspeakers own in

theaters, nightclubs,

conference centers, or other

places of work and entertainment must be

provided with an independent,

correctly-rated, andsecurely-attached

secondary safety, inaddition to the

principle suspension point(s).

Thissecondary safety must prevent

theloudspeaker from dropping

morethan6"should the principle

suspensiondevicefail.
