Multi-Use Theater

Multi-Use Theater

Multi-use theater systems have a number of unique requirements, including:

~Audio from mixing console and multimedia sources
~Bi-amplified Left, Center and Right (LCR) speakers
~Multiple outputs for surround speakers (side and rear)
~Independent gain, EQ, delay and limiting for each output
~Master gain control for each multimedia source

This configuration accomplishes all that...

Many of today’s theaters are designed to support live presentations in addition to multimedia playback. Soundweb™ London can easily handle complex routing of a variety of signal formats.

In this application the digital console is broadcasting six channels of audio across CobraNet™ to the BLU-80. Additionally there are two multimedia devices connected digitally to the BLU-80 via S/PDIF or AES/EBU digital formats. The digital input cards in the BLU-80 convert these signals to the same sample rate at which the BLU-80 is operating. These signals feed a matrix mixer were they can be easily routed by means of parameter presets.

The main screen speakers in this venue are bi-amplified. The Crossover in HiQnet™ London Architect™ can be scaled to provide up to six bands of output providing enough flexibility for any multi-component speaker cluster.

The Crossover provides control over limiting, delay, gain and frequency for each of the outputs allowing the installer to tune the speaker clusters for their best performance within the space.

In this design, ten bands of parametric EQ is provided for each of the 18 system outputs. These filters can be reallocated within the design simply by changing the properties of the processing object to increase or decrease the number of filters needed for any given path of processing.

Although the surround outputs are full range, by using single band Crossovers set to full range we get delay, gain and limiting all from one processing object for each of the surround outputs. By providing discreet outputs for each of the surround speakers and sub woofers, the installer can fine tune the delay, gain, and EQ per speaker to create the optimum acoustical environment.

Utilizing the n-input scalable Gain object to create a six channel gain block allows the user to adjust the multi-channel signals of the multimedia sources from a single master gain fader.

These gain controls as well as the matrix routing parameter preset recalls can all be easily accessed by the operator from the intuitive display of the BLU-10 remote control, integrated into a presentation lectern, projection booth or mix location equipment rack.
