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 medium­complexity 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 chic­est 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.
Output Assign DIP switches determine which inputs are

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 energy­e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.
