Next Generation Driver Technology
JBL 708P leverages JBL patents and next-gen driver technologies to provide unparalleled output with greater dynamic range and extended frequency response in demanding production applications. The JBL 2409H high-frequency compression driver incorporates an innovative low- mass annular diaphragm to deliver smooth response beyond 36 kHz, with extraordinary output and very low distortion. The 728G low-frequency transducer leverages JBL patented Differential Drive technology to reduce power compression for greater sustained output and extended, linear low-frequency performance below 35 kHz. These proprietary drivers allow the 708P to deliver two to three times the output of existing studio monitors.
Patent Pending Image Control Waveguide
First introduced in the JBL M2 Master Reference Monitor, the JBL Image Control Waveguide ensures accuracy and neutrality while providing a wide sweet spot with increased sonic detail. By enabling an acoustically seamless transition between the woofer and high-frequency transducer, the waveguide provides a detailed soundstage and accurate imaging across the entire frequency spectrum. Smooth, neutral on- and off-axis frequency response allows the JBL 708P to “hear the same story” regardless of listening position and room.
Integrated Dual Amplification System
JBL 708P features a built-in dual amplification system that’s optimized for its high-output drivers. A 250W amp powers the 2409H high-frequency transducer and a 250W amp is dedicated to the 725G low-frequency transducer. This combination delivers unparalleled output and detail at greater listening distances, making them ideal for post production or mastering environments.
Comprehensive EQ and Delay
Although the 708P design yields exceptional neutrality in any room, the monitor also features onboard room equalization, so you can compensate for the adverse effects of room acoustics and enjoy the most accurate sound reproduction in any listening environment. In addition to twelve bands of Room EQ, eight bands of User EQ allow customized response curves such as the X-Curve, and compensation for “screen-loss” when placed behind a perforated cinema screen. User-enabled digital delay allows virtual alignment of speakers relative to the listening position, while additional “AV Synchronization” delay is available to compensate for latency in video displays.
Compact Form Factor
7 Series Powered monitors were developed with the modern control room in mind. A compact two-way design minimizes interference with video displays and sight lines, while still providing output that is comparable to larger speakers. The reinforced enclosure includes bottom and rear mounting points, allowing wall and ceiling mounting in either vertical or horizontal orientations.
708P features analog and digital inputs and sample rate converters. AES/EBU digital inputs allow connectivity with a broad range of production hardware, including digital audio workstations (DAW), mixing consoles and digital playback hardware with sample rates of up to 192 kHz. Internal sample rate converters can be enabled to allow connection to digital signals with uncommon sample rates.
