Monitoring and mixing-back-


Using up to 7 ADAM ribbon tweeter speakers and Baggend bass bin we are able to reproduce frequencies accurately between the ranges of 8 Hz and well above 35KHz. The basic 5.1 monitoring setup can be A/B with Mayer, and Tanoy. We have power with various combinations of amps including Mayers, and Yamaha. This monitoring system can be used by any of our mixing configurations through the Grace m906.

Grace Designs m906:

The m906 is a high fidelity 5.1 monitor controller. This device allows us to switch between input and output singals for 5.1 mixes. We can quickly switch between the digital and analog inputs (the mixers, etc.) and also sellect outputs (speaker arrays). This makes A-B-ing material, at the highest rate, a button selection away.

Loudspeaker placement / surround sound-back-

Loudspeaker placement is critical when listening to a surround sound mix. In the studio as well as in the consumers listening space placement of loudspeakers can change the surround sound image. This placement can effect where the exact spot the lister must be in. Extended quad setups provide great surround sound reproduction but to a limited sweet spot (OK if your sit in the only chair on the only spot where the speaker energy meets), and is there for not good for theater or groups. Other set ups have been suggested, by pulling the front speakers closer to center and bringing the back speakers nearer to the reference angle of the ear, a larger sweet spot is created.

Dolby 5.1 design

5.1 surround design for critical listening. The Dolby 5.1 speaker placement, use a 30˚ from center for the front L/R placement and 110˚ from center for the rear L/R speakers. The distance between the center of the circle and the and the outside of the circle should be the optimal speaker/listener distance for the matched monitors.

This graphic shows a 5.1 surround monitoring design using a 110˚ placement for the back speakers. This placement of the rear speakers creates a larger optimal listing zone or sweet spot. The surround sound image created by the 5 surrounding loudspeakers will be accurate any where in the sweet spot.

120˚ 5.1 design

This 5.1 set up is exactly the same as the Dolby set up, but the rear speakers have bee moved to 120˚ from center.

The sweet spot is smaller in size than the Dolby arrangement.

Modified Quadraphonic 5.1

This 5.1 set up uses 90˚ angles for the four left right speakers and an added center speaker.

The sweet spot is small compared to the other setups.

Analog 5.1 console-back-

Sound craft mixing board with TT patchbay:

The Sound Craft 6000 mixing desk is configured for 24 channel multitrack and 5.1 surround sound mastering. The board has a TT patchbay which is used to connect the console to the other systems in the studio. The patch bay is a passive component so it can be used wether the console is powered up or not. The TT patch bay routes the signals in the analog domain and interfaces with the Meitner DAC/ADC for Direct Stream Digital (DSD) engineering for SACD production. Once the signal leaves the DSD domain the signal can than be manipulated and routed through our quality analog components (analog reverberation, eq, compressors, limiters, vocoders, etc...). The sound is manipulated in the analog domain, the fidelity of sound truest to the original.

Digital 7.1 console-back-

Yamaha mixing board with Meterbridge

The Yamaha board is designed to interface with 96KHz 24bit digital equipment, or Analog input which is the digitized at the digital interface rate. The board interfaces with over 64 i/o channels of digital audio or up to 24 input channels of analog. The board has a 8 omni outs providing 7.1 output channels that each sound can be placed. The board has a surround sound panning system that gives precise spacial mixing. The board also has a waves card giving digital mastering tools and surround sound reverberation an added real-time feature. The board can interface with all of our DAC/ADC components both analog and digitally. From multitracking to mastering, this board creates mixes with low noise levels and provides a mixing solution that handles audio at SACD, DVD Audio, and CD standards.
