JBL 705i, 708i Data Sheet

INTRODUCING

COMPACT, INSTALL

The ﬁ rst in JBL’s new 7 Series line, the 705i and 708i models answer the call for next generation multi-channel monitoring in post rooms, broadcast facilities and trucks. Leveraging patented technologies developed for our ﬂ agship M2 Master Reference Monitor, 7 Series deliver detailed imaging, extended frequency response and remarkable output from compact enclosures. Centrally ampliﬁ ed and tuned, and easily installed, 705i and 708i are the heart of an elegant, scalable system for broadcast and post facilities working in immersive audio formats.

KEY FEATURES

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.

• Custom 5” and 8” low frequency drivers in the 705i and 708i

produce remarkable low frequency output, response and high output with minimal power compression.

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.

COMPACT, INSTALL FRIENDLY ENCLOSURES

• Compact enclosures minimize interference

with sight lines to video monitor

• Front ported enclosures allow shelf and sofﬁ t mounting

without degradation in performance

• Rear and bottom mounting points and a range of mounting

hardware allow wall and ceiling mounting in either vertical and horizontal orientation

AMPLIFICATION:

We removed all but the essential components from speaker. The system leverages the superb performance and high density of eight channel Crown CT8150 and DCi8300N amps to:

• Reduce speaker system size and weight.

• Eliminate the need to provide electric power at each speaker location.

• Reduce system complexity. Blue link networked audio in the DCi N amps

simpliﬁes installation and reduces opportunity for system noise.

• LSR705i and LSR708i Dividing Network can be bypassed for

bi-ampliﬁed operation.
