Antiphonal Out on Rodgers 588

[Jesaiah]

Hello Folks,

I have had the possibility to get a fairly good piece of stage PA, a HK Elias w/ two subwoofers and four satellites, each subwoofer equipped with amplifiers thus only needing a line-in-signal.

Considering the fact that our Rodgers organ (a 588) has a fairly undersized speaker setup (two subwoofers and six speakers - and no, not undersized in terms of volume but in terms of "broad sound") AND knowing that the 588 has an additional antiphonal out, I would like to try to connect the Elias to the antiphonal out.

Unfortunately, the company that installed the organ years ago went out of business and the successor is not happy with the thought (understandably, he wants to sell the original equipment). He told me that it might work but he will not send me a drawing of the output section of the organ.

So: is anyone here able to help me out with a connection scheme for the outputs of the Rodgers 588 (or similar model)?

Thank you,

Jes

Having installed several Rodgers organs...

If there is not enough breadth in the sound I would double up the number of speakers per channel on the Rodgers as opposed to adding third party equipment.

Makes me wonder if the issue at hand has more to do with the dealer spending an inadequate amount of time voicing or tonal finishing...or perhaps an inadequate audio system for the room in which it is installed.

I have been told that the audio out board is pretty close (perhaps identical) to the one used in the 578.
The Antiphonal Out seems to be the 9-pin D-Sub connector S-200A which provides a symmetric stereo output. Pins are supposed to be:
1 - shield
2 - Channel 1+
3 - Channel 2+
4 - Channel 1-
5 - Channel 2-
6 - Relay GND
7 - Relay +12V (DC)
8 - empty
9 - Shield

Please note that this information comes without warranty. Try at your own risk. Be especially careful with the 12V which are supposed to trigger the on/off relay of the PA connected (if applicable).

Meanwhile, we had a pro make us a breakout box for this output, containing a power in, three power outs switched by a relay (which is driven in turn by the 12V connection of the organ), and of course the symmetric outputs of Antiphonal #1 and #2.

We used a standard CAT7 data cable for the connection. The D-Sub9 connectors are really small, and we could not find an affordable audio cable with 6 separately shielded wires being thin enough to fit in the plug. So we decided to give that a try. Works perfectly with a length of 30 feet.

Ah, and btw: The 12V for the relay are NOT switched on with the "Antiphonal on" piston but rather with the organ itself. So be REALLY careful and do NOT tamper around with that plug if you dont know exactly what you are doing ...!
