Genelec 1037C and 1038B Tri-amplified Monitoring Systems

System

The Genelec 1037C and 1038B are three-

way active monitoring systems including

drivers, multiple power amplifiers and active

crossovers. The systems are designed for

medium sized control rooms and suited for

music recording studios, film and video post-

production and general broadcasting moni-

toring as well as for mastering suites. They

are designed to perform well both as free-

standing monitors or flush mounted into the

control room wall.

The unique Directivity Control Waveguide™

(DCW™) Technology developed by Genelec

provides excellent stereo imaging and fre-

quency balance even in difficult acoustic

environments. The fast, low distortion ampli-

fiers are capable of driving the stereo system

to peak output levels in excess of 124 dB

SPL at 2 m (1038B) or 126 dB SPL at 1.7

m (1037C) with program material. Versatile

crossover controls allow for precise matching

of the speaker system to different acoustic

conditions.

Drivers and cabinet

construction

On the 1038B the low frequencies are repro-

duced by an 385 mm (15”) bass driver loaded

with a 110 liter vented box. The -3dB point

is 33 Hz and the low frequency response

extends down to 29 Hz (-6 dB). The 1037C

features a 305 mm (12”) bass driver in a 65

liter vented box with the -3 dB point at 35 Hz

and -6 dB at 32 Hz.

Both models share the same midrange

and high frequency driver layout with a pro-

prietary 130 mm (5”) direct radiating cone

for the MF and a 25 mm (1”) metal dome for

the HF loaded by proprietary Directivity Con-

trol Waveguide. All drivers are magnetically

shielded.

Crossover filters

The active crossover network consists of

three parallel bandpass filters. The crosso-

ver frequencies are 410 Hz and 3.0 kHz

on the 1038B and 420 Hz and 3.2 kHz on

the 1037C. Bass, midrange and treble level

controls with 1 dB steps are included in the

crossover to obtain uniform frequency bal-

ance in different acoustic conditions. The low

frequency Tilt and Roll-off controls both have

four 2 dB steps to allow refined low frequency

response tailoring. The crossover network is

driven by an active balanced input stage, fed

by a 3 pin XLR connector. Variable input sen-

sitivity allows for accurate level matching to

console output section.

Amplifiers

The bass, midrange and treble amplifiers

on the 1038B produce 400 W, 120 W and

120 W of short term power. The 1037C has a

180 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 incorporate special circuitry for

driver overload protection and amplifier ther-

mal protection.

Installation

Each monitor is supplied with an integrated

amplifier unit, a mains cable and an operat-

ing manual. Once unpacked place the loud-

speaker in its required listening position,

taking note of the line of the listening axis

(see Figure 1).

Sufficient cooling for the amplifier must

be ensured. The minimum clearance for the

amplifier is 10 centimeters (4”) to any object.

The space adjacent to the amplifier must

either be ventilated or sufficiently large to

dissipate heat so that the ambient tempera-

ture does not rise above 35 degrees Celsius

(95°F). If the speaker is flush mounted into

the wall structure, the amplifier can be placed

separately into an equipment rack using an
