HR Series
The HR824 studio monitors are high-resolution, two-
way, bi-amplied, active monitors employing a 6th-order
Butterworth system with a built-in rear-ring mass-loaded
passive radiator. They feature a 1-inch aluminum-alloy
high-frequency transducer, a high-precision 8.75-inch die-
cast magnesium frame low-frequency transducer, and a
6-inch x 12-inch elliptical at piston passive radiator in the
back. The system is composed of a single, compact cabinet
with built-in control and amplier electronics.
The high-frequency driver is mounted on a massive,
acoustically non-resonant die-cast zinc exponential
waveguide, which results in wide, controlled dispersion
for high-frequency sounds. The unique passive radiator
design provides smooth response down to 39 Hz.
The FR Series™ ampliers found in the HR824 cabinet
are an example of application-specic amplier design
that can be
exercised when designing active speaker sys-
tems.
The low-frequency amplier is rated at 150 watts
rms continuous output, and the high-frequency amplier is
rated at 100 watts rms continuous.
The input panel on the back accepts a line-level input
with balanced 1/4" TRS, XLR, and unbalanced RCA connec-
tors. The connectors face downward so the monitor can be
placed ush against a wall. There is an input sensitivity con-
trol to trim the gain from input to output and adjust for vari-
ous input levels. An acoustic space switch adjusts the bass
response to compensate for corner (quarter space) or wall
(half space) placement. A low-frequency switch selects a
high-pass cutoff frequency of 37 Hz, 47 Hz, and 80 Hz, and
a high-frequency switch provides either 2 dB of boost or cut
above 10 kHz. The power mode switch can be used to turn
the monitor on and off, a function that is duplicated with
the front panel switch, or to put the monitor into auto mode,
where the ampliers revert to standby when no signal is
present for several minutes. The instant a signal appears at
the input, the ampliers seamlessly come back to life and
produce sound.
The cabinet is constructed using 3/4-inch (19 mm)
thick MDF with a 1-inch (25 mm) thick MDF front panel. An
internal H-brace provides additional cabinet stiffness, and
open cell adiabatic "foam ll" acoustic damping material
absorbs internal reections.
