Re: Newbie repeater help

Those who seek knowledge, will become knowledgeable.

(from the electrix website)

My Repeater seems really noisy. Why?

For those of you who are experiencing excessive noise using Repeater in a guitar amp FX loop or when connecting Repeater to a guitar amp input, here's a brief explanation and fix:
Repeater is a unity gain device for _line level_ devices and it has good signal-to-noise specs when used with similar devices. Guitar amp FX loops are not always at line level. This causes considerable noise and unwanted high gain when connected to the FX loop. It's kind of like trying to connect the headphone output of your tape deck to feed the phono input of a stereo amp. No matter how you set the knobs, noise occurs. You've tried turning down Repeater's track levels but this only reduces the audio program level, not the noise.

Here's the fix: Repeater's output needs to be attenuated to match the signal level expected by your amp's FX loop or instrument input. See the attached schematic diagram that shows how you or your solderin' buddy can build an attenuator cable that will do the trick. We've tested this on a Fender "Blackface" Deluxe (guitar to Repeater's instrument input and the output to the Fender's instrument input) and a Peavey Delta Blues (in the FX loop) and it works. Our Johnson Marquis amp had no problem because it's FX loop returns through the Master volume knob which does the attenuation for you.
You can also insert an analog volume control between Repeaters output and the FX Return of your Amp. You can use a small mixer or volume pedal to do this. Keep Repeaters track levels at full volume and optimize Repeaters input so the clip LED turns yellow at the loudest notes. Then use the analog level to attenuate the output of Repeater to create the proper balance with your amp's input.

I don't have an effects loop so,
after the guitar and floor effects,
OK, laugh when ready, could i go through
a passive DI box to lower the signal.?
Before the amp!
Keep laughing
or would it lower it to much?
Is that close to line level?
