using a graphic EQ with panny XR50?

Dave_vega · 12-20-2004, 08:27 PM

readign through the manual it tells you to connect the graphic EQ to the tape inputs..now will this be a analogue connection that will result in noise from the A/D conversion? or how does this work??

Connected to the tape monitor loop, the EQ will only work with analog stereo sources. Digital signals are a separate and independent signal path.

thanks wayne..is there any digital EQ I can use with this receiver? or am I into the whole pre/pro deal with seperate amps..

Dave,

there's a writeup about using the Panny with a Behringer Digital PEQ at http://www.newformresearch.com/

awesome feisal..thanks a ton

edit..for some reason i cannot find the write-up..do you have a direct link?

there's another link under Expert Advice > After Purchase > Digital Amplifier Packages > Settings Overview (I can't direct link it here - it'll pull up the previous link)

Dave,

The info at the Newform Research links FiesalK provided is about using the XR-45 and Behringer DCX-2496 to actively power their speakers, so it probably won’t be of much use to your application.

To answer your earlier questions:

Not what you’re looking for – a budget EQ with the same digital ins and outs we use for home theater equipment. Even if there were, no receiver to date has the connections that are needed – i.e., a digital 5.1 pre-amp output.

Most outboard digital equalizers currently on the market do their digital conversions internally – which means they have analog ins and outs, so they’ll have to be connected the conventional way – and most of those are pro-audio models. The pro models with digital ins and outs use MIDI or another professional interface – which isn’t compatible with home theater equipment.

Not necessarily. The only way you’ll be able to equalize a modern 5.1 channel system is if the hardware is inserted between the pre–outs and main-ins, even if you only equalize the main L/R pair. This doesn’t necessarily mean you’ll need a pre-pro and separate amps, however; many receivers have pre-out and main-in connections for at least some channels. For the channels without a complete in/out loop, outboard amplifiers will be needed.

Wayne,

I agree that there may be no budget PEQs with digital connections, but if I am not mistaken the Panny XR50 does have an optical out - wouldn't this carry 5.1 audio?

(what does it mean when it says "looped output")

Dave_vega · 12-21-2004, 04:17 PM

thanks for the explanation wayne..

feisal..the manual says the optical out for the XR50 is for recording DD, DTS, etc..on a recorder..what else you can do with it I have no clue..

Wayne A. Pflughaupt · 12-21-2004, 06:40 PM

Thanks for looking that up, Dave – I figured that’s what the optical output was for.

Since it’s a record output, its level will not change with the main volume control, so it’s useless as an output for a digital equalizer – which as noted, would have to connect between the pre-outs and main-ins.

In a perfect digital world, a receiver would have a single 5.1 digital output (or perhaps an output for each channel) that could feed the digital inputs of a multi-channel equalizer, and the EQ would have digital outputs that would feed to the digital inputs of a multi-channel digital amplifier. As it is now, any digital equalizer you would want to use has to have analog and digital conversions on both ends.

The next best thing –perhaps even better, actually - is having digital equalization built into the receiver. This is actually becoming fairly common these days.
