JBL 708i 8 Inch 2-Way Master Reference Monitor (Each)

About: JBL 708i 8 Inch 2-Way Master Reference Monitor (Each)

The first in JBL’s new 7 Series line, the 708i 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, 705i and 708i Studio Monitors are the heart of an elegant, scalable system for broadcast and post facilities working in immersive audio formats.

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 Enclosure

• Compact enclosures minimize interference with sight lines to video monitor
• Front ported enclosures allow shelf and soffifit 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

Next Generation Systems for Post and Broadcast Production in Control Rooms and Trucks

• Modular and scalable for number of channels and room size
• 7 Series Monitors and the JBL M2 Master Reference Monitor can be combined to produce a wide range of systems
• Compact enclosures and mounting hardware allow versatile mounting options and unobstructed sight lines
• Centralized amplification and processing eliminates the requirement for power source at each speaker location
• BSS BLU link Networked Audio for ease interface and reduced system noise
• Harman HiQnet equipped components can be centrally controlled via hardware, software or wireless tablet

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.

Signal Processing and Control

• Speakers are Centrally Processed using BSS Soundweb London Signal Processors.
• The BSS London allows perfectly matched tunings for the LSR708i and LSR705i models.
• Available Room tuning filters provide a more consistent listening experience in a range of post production and broadcast rooms.
• Inputs to the system can be analog or digital.
• Session functions such as level, individual speaker solo, fold down and more can be centrally controlled via BSS hardware, Audio Architect Software, or tablet via a wireless router.
