If so, what features would you like to see (or not) in an AC12 alternative product?
  • An active system for longer cable runs?
  • Drop the RS232 connector, given that it's rarely used in day-to-day situations?
  • What about DIN comms? a) Use only BNCs on the product and bundle BNC-DIN adapter cables, b) Include DIN and BNC connectors on the product or c) Exclude DINs completely?
  • Could one get away with just a single comms (BNC) connector on the product, that is switchable between Master and Slave?
  • Your suggestions here!

The cheapest option would be a passive product with a single BNC comms connector that can be switched between Master and Slave. This would be fine for my purposes but may be too limiting for other people with more complex systems, so I'm keen to hear your thoughts.

If a specification can be agreed upon then I'll produce a prototype for feedback and review by some esteemed members.

T42 Nobody else seems to have replied to you really. I'm in, what I feel, is probably a very common position. My current Meridian kit is all significantly pre-SL. If I ever wanted (could afford) to upgrade I have to factor in SL conversion halfway through the process or spend twice as much (watch my lips, it ain't gonna happen). A decent priced SL to 5M/5S (or vice-versa) solution would be a great idea. In relation to your specifics

How long before you need active?
Agree if there's an RS232 on the back of each DSP it doesn't need repetition for me.
My older DSPs are DIN comms, I feel I'm your target audience in a way but I'm Mk1 (albeit 24/96) DSP5k. if every newer DSP has BNC comms you're probably talking sense.
See above, but I do see the sense in switchable master/slave.

Does that help?
