Thanks Jim for your detailed response!
OK, so the exact situation is this:
The Quad preamp is currently situated in a mastering
studio which, as part of a refit, is having all
the amplifiers and outboard gear moved into a
separate adjacent room to take all the noise out
the studio itself.
OK, understandable. Moving the equipment to an adjacent room to cut down on clutter, and some distortion effects from not having a "clean" soundroom.
To have the preamp in an adjacent room adds an additional requirement, assuming there isn't a clear glass partition or window for the IR signals to penetrate to reach the IR controlled equipment: RF.
So, anyway, because the amp is not adjustable
without the remote, and because it remembers its
level when its switched off and on again, I dont
see the need to have any feedback from the amp
to the remote.
I would be willing to replace the Quad preamp
if there was a preamp out there with a full remote
giving a volume and source display if you know
of one?
Not that I'm aware of, but there may be a simpler solution.
To keep the preamp inside the studio would involve
running long cables backwards and forwards between
the power amps and the other gear, which would
obviously sacrifice the sound quality and increase
hiss & hum etc., not to mention add loads of wiring
to the room.
The preamp itself does not have a volume control
but has a level LED meter. The remote does still
just work but is getting very cranky and the buttons
are on the way out.
I'd suspect that the oem remote could be "rejuvenated". There is a remote button product on the market, but a cheaper, simpler alternative is Loctite rear window defroster kit. It's a conductive substance you just "paint" on the button contact surfaces (clean good with isopropyl alchohol first).
It is old gear but works very well, and is a hot
favourite for this sort of application, mainly
because of the big chunky remote control which
can sit right on the workstation.
However, unless the amp is in view it is impossible
to tell how loud the system is set, and with 2
500W power amps, you could potentially end up
seriously damaging your health
True. But have you considered an analyzer in the room? It doesn't have to be connected to the equipment involved. Most have a display, sometimes the displays can be varied as to what it's reading, ie. SPL. A full unit is fairly small, and should have it's own mic, usually with about 20 feet of cord so you can place it almost anywheere you want in the room. The actual readout portion just requires AC power (120 volt), and could be placed where the artist, or whomenver can easily see it, then with a IR>RF repeater type system (or a rf/ir remote with command center) could raise or lower the volume by the actual sound level in the room.
Assuming the "lead singer" is doing double duty as the "engineer", he could still have complete control of the preamp, including volume levels, and with the meter giving feedback on sound level, he could impose a "self-imposed" limit of his choosing, ie. 100dB, 110dB, etc and make adjustments based on the meter readings thru the remote.
