6.7˝ and 8.75˝ 2-Way Active Near-Field Monitors

One of the most accurate near-field monitors ever built, thousands of recording studios and

post-production facilities rely on the HR824 to reveal details that comparable monitors sim-

ply cannot resolve. Frequency response is an astonishing 38Hz to 20kHz ±1.5dB. To achieve

such a sweet spot and smooth response, the HR824 uses technology

not found in typical vented-box near field monitors. A cast zinc

exponential waveguide disperses

sound evenly and integrates the output of the HF and LF

drivers. Its servo-coupled LF transducer works in conjunction

with a rear-firing passive transducer to extend low octaves and

eliminate vent noise. The HR824 uses two separate high-current

amplifiers with discrete circuitry. And it is fully stuffed with dense

foam to fully damp internal vibrations before they can escape

through the LF transducer.

Employing the same acoustic technology as the HR824, but in a

compact version, the HR624 is deal for rear surround sound

channels in existing HR824 front left/right systems or as a main monitor system in control rooms and editing suites where

space is at a premium. When using the HR624 as the primary monitor in project rooms or off-line editing suites, mixes will

flawlessly transfer to an “A” room that employs HR824’s. The HR624 is flat ±1dB from 55Hz to 20kHz.

◆ Wave guide technology matches the high

frequency dispersion pattern to the bass

transducer for a seamless midrange transi-

tion. Furthermore, the high frequency trans-

ducer is recessed, providing acoustic align-

ment of high and low frequencies.

◆ 1˝ MDF (Medium Density Fiberboard)

front board. Internal cavity is filled with

high-density foam to absorb the internally-

projected midrange before it can exit

through the low frequency transducer cone

◆ 1˝ high-frequency aluminum dome driver

with ferrofluid-cooled voice coil.

◆ 6.7˝ (HR624) or 8.75˝ (HR824) RCF

Precision low frequency transducer with

mineral-filled polypropylene cone, die-cast

magnesium frame and extra-long-throw

voice coil are servo-coupled with a

dedicated 100-watt or 150-watt amplifier

◆ High frequency shelving control adds or

attenuates frequencies above 10kHz by 2dB

◆ 40-watt (HR624), 100-watt (HR875) high

frequency amplifier. Proprietary Fast

Recovery circuitry prevents latching when

the amps are driven at their maximum.

◆ Low frequency switch with 49Hz (full range)

and 80Hz roll-off settings (HR624); 37Hz

(full range) 47Hz and 80Hz roll-off settings

(HR824)

◆ Magnetic shielding

◆ Input sensitivity control, ideal for dealing

with sensitive artists or insensitive clients

◆ Acoustic space switch allows bass

optimization when placed freestanding (full

space), against back walls (half space), and

corner placement (quarter space)

◆ Overload LED indicates when protection

circuitry kicks in

◆ Three mode power switch:

On, Auto On

(with front panel clipping

LED and a signal

present/power indicator),

and standby

◆ XLR and TRS jacks accept virtually any

line-level input from a mixing console

◆ Power cord and all inputs (balanced XLR

and 1/4˝ TRS, unbalanced RCA) are

mounted on a downward-facing, vertical

panel. This allows speaker placement

close to walls and eliminates strain on the

connectors.
