EUROCOM Installed Sound

Combining superior performance and extraordinary

exibility with unprecedented value and style, the

EUROCOM SN2408 mixer-amplier is an innovative

yet practical solution for distributed sound in medium-

complexity environments. Incorporating BEHRINGER’s

exclusive DualDrive technology, the SN2408 is powered

by two independent mono ampliers, one with a high

impedance output that may be set to either 70 or 100 V,

and the other with a standard low-impedance output.

This uniquely versatile conguration addresses the needs

of hybrid distributed/low-impedance systems, allowing

easy installation and conguration of multi-zone setups in

bars, recreation facilities, conference rooms, boardrooms,

hotels, and other venues.

With a sleek, compact exterior that's at home in the chic-

est of settings, the SN2408 can be shelf-mounted within

convenient reach rather than hidden away in a back room.

The clear, intuitive front-panel design, which allows easy

operation by non-technical personnel, includes level

controls for all inputs as well as high and low EQ settings to

optimize the sound for any environment. The front-panel

master volume knob is surrounded by an indicator ring that

glows yellow for power on and ashes red at the onset

of clipping. Paging functions are automated so that user

action is not required to duck background audio

during pages.

The SN2408 includes three input channels that accept

balanced or unbalanced signals via XLR/TRS (1/4-inch)

combination jacks or 4-pin Euroblock connectors. Each

channel is equipped with a three-position switch to select

line, mic, or mic with phantom power (48 V). Two additional

input channels, each with a pair of RCA jacks that are

summed internally to mono, allow playback from external

sources such as CD/MP3 players, cable boxes,

and radio/TV tuners.

Loudspeakers connect via a 4-pin Euroblock connector

wired for both high-Z and low-Z

outputs. Two additional 3-pin Euroblock connections,

each with an associated level control, include a Tel/Page

input for integration with telephone paging systems and

a Zone 2 line-level output to feed a supplemental sound

reinforcement system. Eects send and receive, used to

insert external processing such as dynamics or EQ, is also

provided for each of the two amps using line-level

RCA jacks.

Extensive back-panel control allows the installer to rapidly

customize the SN2408 to the needs of a specic installation.

Switches are provided to select mains voltage (115 or

240 VAC) and high-Z output (70 or 100 V). A Balance control

adjusts the relative levels of the two power ampliers.

included in the Zone 2 output and enable/disable external

processing inserts for each amp. Mute Assign DIP switches

enable/disable mute send and receive signals for the three

main inputs plus Tel/Page, and a Mute Depth control adjusts

the degree of attenuation.

SN2408 operation is both cool and extraordinarily energy-

ecient thanks to transformerless Class-D ampliers that

utilize switch-mode power supplies. The low-Z amplier

delivers 80 W RMS into 8 Ω and 125 W RMS into 4 Ω, while the

high-Z amplier delivers 80 W RMS at 70 V and 160 W RMS at

100 V. Each amplier is protected with DC and thermal

overload protection, as well as by automatic limiting that

prevents overload, clipping, and distortion.

With every detail thought through from both the installer and

end-user perspective, the SN2408 oers the ideal balance

between versatility and ease-of-use, making it a perfect match

for commercial sound requirements in retail, hospitality, oce,

medical, educational, and industrial spaces.
