Hi all

Does anybody have experience on how to remote control a Crown DL-2 preamp? And how can I connect 2 (two) DL-2 (Master and slave) together and remote control them?

I would like to control from my ipad.  It has a ieee 488 port on the back and the users manual says it can be controlled from a computer.

Is there any "old" crown specialist that could help me?

Thanks

There are two ways to remote the DL-2. I took a simple path to build a infra-red remote. You can use the remote connector to build one simply completeing to ground (if I remember correctly, could be to a voltage available at one of the pins on the connector) each switch function. This gives you control over volume(L,R,L+R up and down) and mute. The next level of remote requires passing data to the DL-2 and is much more complex as it requires a computer interface. The manual has diagrams and instructions for both which can be downloaded from this website.

Additionally the 8088 and PIA that is discussed could be found in many experimenter kits which may still be available or you could use a PC (X86) with a PIA card and simply use the program given as an example to be used in a "call" statement in Basic to control one or more DL-2s.

The connector is still available at either Mouser electronics or Allied or Digiplex where I got mine. Hope this was helpful.

Sorry haven't checked in awhile. I purchased online a twelve switch infrared remote control kit. I wired the individual switches on the receiver board to the remote jack. I think I found the connector at Mouser Electronics. The kit comes with a hand held remote. Oh and I purchased a plastic hobby box from Mouser as well with a red translucent plastic front insert to allow the infrared signals to get to the ir diode on the receiver board. Total cost less then $50.
