Three-Way Active Loudspeaker

The Genelec HT320BC is a three-way
active loudspeaker designed for medium
sized high quality Home Theater systems.

The HT320BC is a dedicated, magneti­cally shielded center channel version of
the matching HT315B, offering a compact
solution where space is insufficient for
the standard enclosure. Designed as an
active loudspeaker system, it contains a
loudspeaker cabinet with multiple drivers
and a separate 3U RAM5 amplifier unit
containing power amplifiers, active cross­over filters and protection circuitry. Neutrik
Speakon connectors are provided to facili­tate wiring and system connection at cus­tomer facilities. The loudspeaker performs
best when flush-mounted into a solid wall
structure.

The unique Directivity Control Wave­guide™ (DCW™) Technology developed
by Genelec provides extremely stable and
accurate imaging and frequency balance
even in difficult acoustic environments. It
also results in perfect phase and delay
uniformity at the crossover frequency. Fur­thermore, versatile and precise crossover
controls allow for accurate matching of

the loudspeaker system to different room
acoustic conditions.

Every amplifier is calibrated individu­ally with its designated loudspeaker unit
before packing. This eliminates the effects
of component tolerances and ensures
consistent quality and long term reliability.

The low frequencies are repro­duced by two long throw 250 mm (10”)
bass drivers featuring a -3 dB point at
33 Hz. The HT320BC model shares the
same midrange and high frequency driver
layout with the HT315B, consisting of a
Genelec proprietary 130 mm (5”) mid­range cone driver and a 25 mm (1”) metal
dome HF driver loaded by the proprietary
Directivity Control Waveguide™. All driv­ers are magnetically shielded to minimize
stray magnetic field and interference.

The amplifier unit contains an active
crossover. This is the ideal method for
dividing the input signal between the driver
units, allowing the overall response of the
system to be optimized to an extent impos­sible with a passive system. Variable input
sensitivity and XLR line level input con­nector provide easy connection and accu-

rate level matching to the preamplifier or
decoder.
HT312BC has a 400 W amplifier for the
low frequency driver and 120 W amplifiers
each for midrange and treble drivers. The
amplifiers are designed to operate at very
low THD and IM distortion values and are
capable of driving a stereo system to peak
output levels in excess of 123 dB SPL at 2
m with music material.

cial circuitry for driver overload and ampli­fier thermal protection, as well as an
“Autostart” function for automatic switch­ing between “Standby” and “On” power
modes. The power mode can also be
changed with a 12 V trigger voltage or
external switch or relay type remote con­trol. An LED indicator on the DCW™ plate
displays the system status. “Autostart” and
“Remote control” functions can be enabled
or disabled as required.
