JBL LSR708i 8" Master Reference Monitor (Single)

Linear Spatial Reference 8" Master Reference Studio Monitor

Next Generation Systems for Post and Broadcast Production in Control Rooms and Trucks
The first in JBL's new 7 Series line, the LSR705i and LSR708i models answer the call for next generation multi-channel monitoring in post rooms, broadcast facilities and trucks. Leveraging patented technologies developed for our flagship M2 Master Reference Monitor, 7 Series Studio Monitors deliver detailed imaging, extended frequency response and remarkable output from compact enclosures. Centrally amplified and tuned, and easily installed, LSR705i and LSR708i Studio Monitors are the heart of an elegant, scalable system for broadcast and post facilities working in immersive audio formats.

Amplifier and Processor Requirements
The LSR708i and LSR705i models require use of an external power amplifier capable of delivering 300 watts per channel and also Harman Professional digital signal processing. The following Harman Crown Audio power amplifiers include the required Harman Digital Signal Processing and are recommended:

DCi 2|300N 2-channel power amplifier
DCi 4|300N 4-channel power amplifier
DCi 8|300N 8 channel power amplifier

If you wish to use an amplifier other than the Crown DCi models specified above, you must also use one of the following HARMAN BSS Soundweb London Processors: BLU-50, BLU-100, BLU160 or BLU800 signal processor.

TECHNOLOGY

Patent Pending Image Control Waveguide
First introduced in the JBL M2 Master Reference Monitor, the Image Control Wave Guide technology allows
A seamless crossover and uncolored response in the critical dialog range.
Neutral off-axis response for greater accuracy and room-to-room consistency
Detailed imaging and a coherent transition between screen channels, surrounds and overhead speakers.

Next Generation Driver Technology
Meeting the dynamic range and extended frequency response requirements of today's production formats, 7 Series incorporates JBL next generation "Super Drivers."
The new 2409H High Frequency transducer incorporates an innovative low-mass annular diaphragm that delivers smooth response beyond 40 kHz, with extraordinary output and very low distortion.

JBL developed custom low frequency transducers for remarkable performance of the 7 Series
New 725G and 728G 5" and 8" high-excursion low frequency drivers in the 705i and 708i deliver continuously high output with minimal power compression and low frequency response into the 30Hz range.
