Eq on channel a doesn't work on 2 units

I have been having a loud hum on channel a of Peavey eq215's. when I hook into channel b it works fine. Why doesn't channel a and b work together on either unit. Peavey CS 800 and a Crown XLD802 into Peavey eq 215. one per amp going into a PV14 board.

It could be an internal ground connection on the EQ that's broken ( maybe inside the connector) ..I repaired numerous peavey products and broken grounds are common.

Hi i have peavey xr 8300, with no output. It powers up, but no sound ,only a slght hum from the speakers.


Are you good with replacing surface mount components while wearing 5 to 10 power loupes to see what you are doing?

Do you have a controlled heat soldering station, anti static workstation, 100 mhz oscilloscope, audio signal generator, capacitor analyzer, and familiar with reading schematics ???

Do you understand the shock hazards and risk of working on energized audio equipment under test..if so I can start to help you with this repair.

How too hook up a audio source eq100 to my harman/kardon avr 1600. i have in the tape outs and ins on both devices but its not working PLEASE HELP!!!!!!!!!!!!!!!

Be advised that the engagement of any device in a Tape Monitor loop on a late-model Audio/Video Receiver will effectively tie the receiver down to stereo-only analog sound reproduction. I'll explain.


The connections themselves are fairly simple but it pays to understand what happens in the loop.


In general, any Line-Level external processor (EQ, dynamic range expander, etc) will go into a Tape Monitor loop on a receiver. A Tape Monitor, when engaged, sends the stereo analog signal Out to the Processor, massages it and returns it to the receiver via the Tape Monitor IN connectors to be passed on to the receiver's internal processes (volume, tone, whatever).


Old school analog stereo-only receivers consistently work this way. Newer digital and audio/video receivers introduce a couple of problems: 1) digital sound processing to simulate a variety of soundfields; 2) multiple output channels, either discrete or digitally-generated.


The latter requires that whatever signal is being processed experiences a maximum of one analog-digital-analog conversion.


EVERYTHING analog coming into the modern digital receiver is automatically converted to a digital signal for internal processing unless you choose a STEREO-only or STEREO-Direct setting. Consequently, no further external analog-digital conversions would be allowed if, say, a Tape Monitor circuit was activated, and a possible feedback loop could otherwise be created in a digital-sourced selection (output to its own input), so the unit is wired to treat the Tape Monitor as the first analog step in the process and defeats any pure digital sources.


In a multichannel unit, what would happen to the other channels if you sent ONLY the Front Left & Right out for processing? The rest would NOT be processed. That logical problem also plays into the decision to defeat digital sources if the Tape Monitor is activated. I don't totally agree with the engineers but that's the way it is. Nature of the digital beast.



Okay, back to the hook-up:



You have to select any available 'tape loop' containing an overrideable analog 2-channel Out and In. That would be Video 1 or Tape on the HK.


Receiver Tape Out (Rec) - to the External Processor (EQ, whatever) Preamp-, Rec, Line-In;


Receiver Tape In (Play) - from the External Processor (EQ, whatever) Preamp-, Play , Line-Out.



So, to sum up, you can only use the EQ or any outboard processor for analog stereo sources. If you actually want to use an analog recording deck you could place it within the typical Equalizer's own Tape Monitor loop(s). Many have two to facilitate equalized dubbing between decks.


The EQ has its own Tape Loop(s) to replace the one it uses. Actual Tape Decks or Processors can nest into those loops and be engaged or bypassed via controls on the EQ or Processor.

Looking to hook up an audiosource EQ100 to an a sony cass deck


Simply place it in line with the analog input. Or install it in a Tape Loop on your integrated amp/receiver and attach your tape deck to ITS tape Loop.

Ins to Outs


Receiver Tape Out (Rec) - to the External Processor (EQ, whatever) Preamp-, Rec, Line-In;


Receiver Tape In (Play) - from the External Processor (EQ, whatever) Preamp-, Play , Line-Out.

Be advised, using analog processors on digital-capable multichannel elcetronics will only work for analog 2-channel sources.

CONNECTING


you can do it passive. no idea with your ampli, but if it does have a bridge then you can hook your eq there, series. if it doesn't have then via tape monitor 2 of your kenwood.

onkyo recvr tape 2 record to - kenwood eq in
onyo recvr tape 2 playback - kenwood eq out

that's all. if you want your eq to be active, then switch your reciever to tape2, all selected input in your reciever will by pass through your eq then back to kenwood. you dont have a function for tape 2 input then but your eq will have an extra input for tape, that you can use for your second tape, it will be active only if your reciever is set to tape 2. i hope you got it right.

post back if you got it done
