TMC-1 Ashly ne8800 DSP Monitor Controller Interface

In response to customer requests we have now interfaced the TMC-1 to the Ashley ne8800 DSP processors.

Ashley ne8800

The Ashly ne8800 is an interesting unit, limited by having only 8 inputs and 8 outputs with summing, but unlike the NTP digital router it has DSP on both inputs and outputs - Summing, Equalization, Delay, Crossover and Dynamics. Supplied with Analog in/out as standard  AES/EBU and Dante are available as an option.

The Summing allows  the TMC-1 to implement down mixing, I have included the standard TMC-1 set of formats:

  • Mono Sum

  • Stereo only

  • Stereo Down Mix

  • 5.1 Down Mix from 7.1

  • 5.1 with side surround routed to both side and rear

  • 7.1

  • Atmos (7.1.4 on this implementation).

The first unit shipped with Ashly software is a PD-3 which combines a PD-1 with a TMC-1. The PD-1 is improved by adding a OLed display, ethernet port and the new PD-2 software.

PD-3 Film Monitor Remote

The limited number of inputs and outputs made designing systems with the ne8800 a challenge, however the TMC-1 is able to talk to multiple ne8800's increasing the possibilities.

The initial request was for a 7.1.4 film post production room which used two ne8800's. one for the 7.1 inputs and outputs, the other for the 4 overhead speakers, There were 4 unused inputs and outputs on the second ne8800, by routing the Left and Right outputs from the first ne8800 through the second ne8800 we were able to add a stereo input and a mini stereo output.

The initial design has a fixed configuration but if there are a requests for further systems I will write a system configuration program similar to the TMC-1-Penta2 program that will enable users to define inputs and outputs by their unit and channel number.

Using the AES/EBU and Dante inputs or adding a further ne8800 it is possible to select more inputs. To add Cue Inputs, Cue sends, AFL, talk back and listen back would require a third ne8800. It is possible to make a large ATMOS system from multiple ne8800's all controlled from a single TMC-1.
