Genelec 1238APM 3-Way Smart Active Master Studio Monitor

Three-Way Studio Monitor System with Precision and Power
The Genelec 1238APM SAM™ Studio Monitor is a tri-amplified three-way monitoring system designed for professional recording, mixing, mastering, and post-production environments. It features a powerful 15" woofer, a custom 5" midrange driver, and a 1" tweeter—each powered by its own dedicated amplifier channel. Engineered for precise frequency response and wide dynamic range, the 1238APM delivers transparent playback across the entire audio spectrum, making it ideal for critical listening applications.

Remote RAM-L Amplifier for Flexible Installation and Cooling
At the heart of the 1238APM is Genelec’s advanced RAM-L (Remote Amplifier Module), which houses the 500W LF, 250W MF, and 200W HF Class D amplifiers. This unit is mounted on the back of the enclosure by default but can also be rack-mounted for thermal isolation or space management. The remote amplifier simplifies integration in control rooms and keeps heat away from the monitor cabinet, preserving component longevity and performance.

Smart Active Monitoring with AutoCal and GLM Integration
As part of the Genelec SAM™ series, the 1238APM is fully compatible with the Genelec Loudspeaker Manager (GLM) software, enabling automated calibration via AutoCal™. This system measures room acoustics and adjusts each monitor's frequency response, phase, level, and timing for optimal accuracy in any environment. It’s especially useful in mastering rooms, broadcast facilities, or post suites where room conditions vary or require precise correction.

High Output and Controlled Directivity for Larger Spaces
With a 15" woofer pushing 500 watts, the 1238APM delivers substantial low-frequency extension and SPL capabilities suitable for medium to large control rooms. Its advanced Directivity Control Waveguide (DCW™) ensures consistent off-axis response and broad listening area coverage, providing accurate stereo imaging even when working outside the sweet spot. Whether you're tracking orchestral scores or mixing immersive content, the 1238APM holds up under demanding monitoring conditions.

Custom-Built Midrange Driver Designed in Finland
One of the key elements of Genelec’s three-way design is its dedicated midrange driver, hand-built in the Genelec factory in Iisalmi, Finland. This proprietary 5" driver has been engineered for low distortion and maximum transparency in the vocal and critical mid-frequency range. When paired with the powerful low-frequency driver and high-definition tweeter, the result is unmatched clarity and balance throughout the spectrum.

Fully Integrated with Other Genelec SAM Systems
The 1238APM is designed to work seamlessly with other monitors and subwoofers in the Smart Active Monitoring lineup, allowing you to build scalable multichannel systems for stereo, 5.1, or immersive formats like Dolby Atmos. Whether you’re expanding an existing setup or building a new system from the ground up, integration with other SAM models ensures consistent performance and centralized control through GLM.

Optimized for Broadcast, Post, and Mastering Environments
Built for long-term reliability and exceptional audio performance, the Genelec 1238APM is the monitor of choice for engineers who demand accuracy at high SPL levels. From broadcast networks and mastering suites to high-end production studios, this speaker delivers reference-grade monitoring with DSP calibration, remote amplification, and uncompromised sound.
