JBL Professional 3732-M/HF-T & 3732-T - M/HF Module for 3732T and Tri-Amplified ScreenArray System

JBL Professional 3732-M/HF-T & 3732-T - M/HF Module for 3732T and Tri-Amplified ScreenArray System

The JBL Professional 3732-M/HF-T and JBL 3732-T suite covers two key needs in commercial movie theaters and behind-the-screen auditoriums. The 3732-M/HF-T is the dedicated midrange/highfrequency module for the tri-amped version of the 3732 system, featuring two 165 mm (6.5") 165H midrange drivers and a 75 mm (3") titanium-diaphragm 2432H compression driver with a 38 mm (1.5") exit. It employs Optimized Aperture waveguides for even coverage and low distortion, and offers separate MF and HF inputs in tri-amped scenarios.

The JBL 3732-T is the tri-amplified three-way system of the ScreenArray family: it combines the 3739 LF section (dual 15" M115-8A in a 4509 LF cabinet) with the mid/high frequency array. It provides 90° (H) and 20° up/30° down (V) coverage, a system sensitivity of 104 dB (2.83 V/1 m) and a response of 40 Hz to 19 kHz in a behind-screen configuration with a contained depth of 450 mm. The ScreenArray philosophy guarantees smooth acoustic transition between ways, directivity control and extremely low distortion in small and medium-sized rooms.

Benefits for the installer and the room

• Accurate digital soundtrack reproduction with low distortion and smooth transitions between tracks.
• Controlled directivity for uniform coverage from seat to seat, reducing leakage and reflections in the room.
• Shallow profile (450 mm) that facilitates installation behind micro-perforated screens.
• Modularity : replacement or upgrade by sections (LF 3739, M/HF or M/HF-T) without replacing the entire system.
• High efficiency (104 dB sensitivity) to achieve reference levels with lower amplification power.

Use cases

• Small and medium-sized movie theaters requiring a behind-the-screen LCR system with high coverage control.
• Upgrading existing ScreenArray 3732 systems to tri-amp operation using the 3732-M/HF-T module.
• Auditoriums and screening centers with active processing and dedicated multi-channel stages per channel.

Frequently Asked Questions

• What's the difference between the 3732 and the 3732-T? The 3732 is bi-amped (LF on one channel and M/HF on the other, with a passive crossover between the MF and HF). The 3732-T is tri-amped (LF, MF, and HF with independent channels and an active MF↔HF crossover at 1.2 kHz).
• Does the 3732-M/HF-T work without the 3739 LF module? No, it's part of a three-way system behind the screen and must be integrated with the LF section and appropriate processing.
• What is the required depth behind the screen? 450 mm for both the LF 3739 section and the M/HF module, and 450 mm for the complete system.
