The Genelec 1238CF master monitor is a three-way loudspeaker with dual 8″ woofers, 5″ midrange driver and 1″ metal dome tweeter with network capabilities and automatic room compensation—free standing or flush wall mounted
Compact, by master monitor standards, the Genelec 1238CF is a three-way loudspeaker with dual 8″ woofers, 5″ midrange driver and 1″ metal dome tweeter with Genelec’s Directivity Control Waveguide (DCW). It has integrated rear-panel amplifiers and digital signal processing (DSP) circuitry. Thanks to Genelec’s Smart Active Monitor (SAM) implementation the 1238CF is able to be combined in a software controllable network with Genelec’s 8200 and 7200 series monitors and subwoofers. The 1238CF is optimized for systems with single or multiple subwoofers for use in medium-sized control rooms. Genelec Loudspeaker Manager (GLM™) 2.0 software allows for the fine adjustment of up to 30 individual Smart monitors and Smart subwoofers to accommodate any multi-channel audio set-up, while AutoCal™ compensates for room anomalies automatically calibrating your system to your acoustic environment. Able to operate as a free-standing monitor or flush-mounted into a wall, the 1238CF is eminently suited for music recording studios, film and video post-production, general broadcasting monitoring, and mastering suites.

INSIDE THE BOX—Genelec 1238CF
Networked Smart Active Monitor (SAM) Systems
Now that studio real estate is at a premium, more and more productions are done in smaller facilities, whose dimensions cause audio anomalies that are difficult to deal with. However, Genelec’s advanced SAM Systems are can automatically adapt to acoustic environments and correct for levels, delays and room anomalies. SAM Systems can be controlled via Genelec proprietary Loudspeaker Manager (GLM™) network and software, enabling you to build a highly flexible and reliable monitoring system. If the monitors have to move between rooms, you can rely on SAM technology to give you absolute consistency, a neutral sound stage, and low distortion.
Directivity Control Waveguide (DCW)
Genelec’s DCW technology, developed and refined over 30-plus years, significantly improves the performance of direct-radiating multi-amped monitors. The Directivity Controlled Waveguide shapes the radiated wavefront in a predictable dispersion pattern resulting in a very linear overall frequency range and uniform power response. Minimized early reflections provide a wide and consistent listening area with accurate on- and off-axis sound reproduction.
Another important advantage of a controlled wavefront is that the frequency balance of the room’s reverberation field is essentially the same as the direct field from the monitors. As a consequence, the monitoring system’s performance is less dependent on the room’s acoustic characteristics.
Sound image width and depth, critical components in any listening environment, are important not only for on-axis listening, but also off-axis. This benefits both the engineer and clients outside the sweet spot, particularly in large control rooms.
DCW Technology key benefits:
Flat on- and off-axis response for wider usable listening area
- Increased direct-to-reflected sound ratio for reduced control room coloration
- Improved stereo and sound stage imaging
- Increased drive unit sensitivity up to 6dB
- Increased system maximum sound pressure level capacity
- Decreased drive unit distortion
- Reduced cabinet edge diffraction
- Reduced complete system distortion
Active monitors, as opposed to powered monitors, use active crossovers, which electronically splits the audio into separate frequency bands. These bands in turn can routed to individual power amplifiers, which drive transducers optimized for each frequency band. The active design offers several benefits. By connecting power amps directly to the drivers, damping control on the driver’s voice coil is maximized, reducing unwanted changes in the driver’s electrical characteristics, which can improve transient response. Active technology can produce superior sound output vs. size vs. low-frequency cut-off performance. The 1238CF comprises a factory-aligned system (amplifiers, crossover electronics, and enclosure-driver systems).
Active crossovers come in both digital and analog varieties. Genelec digital active crossovers include additional signal processing, such as driver protection, delay, and equalization. The flat frequency response of a high-quality active loudspeaker is a result of the crossover filter response, power amplifier responses and driver responses in a loudspeaker enclosure.
Using the active approach enables frequency response adjustments and optimization of the full loudspeaker system, placed in various room environments, without expensive external equalizers. The end result is a simpler, more reliable, efficient, consistent and precise active loudspeaker system.
Intelligent Signal-Sensing technology
Intelligent Signal Sensing, ISS circuitry tracks the signal input of the loudspeaker. If no audio input is detected for given period of time, it puts the loudspeaker to “sleep” or a low-power state that consumes less than 0.5 watts. When an input signal is detected, the loudspeaker immediately turns itself on. Basically, the loudspeaker system will start saving power as soon as work is interrupted.
Maintaining reliable performance in the studio is essential, which is why Genelec builds protection circuitry into the 1238CF. With signal level detection, it prevents driver failure by reducing signal level automatically in case of sudden peaks or constant high levels.
Protection circuitry features and benefits:
- Reduces the output level when required, (e.g. when driver voice coil temperature reaches the safe limit) which significantly improves system reliability
- Protection circuitry specifically optimized to each loudspeaker and subwoofer enables maximum system output levels
OUTSIDE THE BOX—Genelec 1238CF
Rear-panel connections on the 1238CF include a mains power switch, GLM 2.0 control network connections, mains input connectors, 12V remote connector, standalone user interface level control, analog input connector, digital AES/EBU thru connector, and digital input connector.
There are two groups of control switches. Group one includes bass roll-off, bass tilt, desktop low-frequency control, and treble tilt. Group two controls include Stored/Manual control, which selects between rear-panel controls and settings stored in the speaker’s memory. An AES/CH switches select audio channel(s) available on the AES/EBU cable. Group two also includes driver mute and system level controls.
The 1238CF combines classic studio design with innovative technology and stellar sound for recording studios, film and video post-production facilities, broadcasters and mastering suites. For more information, call or chat online with your Westlake Pro Sales Consultant today.
