Eich T500 as a power amp

[redtomfunk]

Hi all,
I have tried going in the effects return of my Eich T500 using an external preamp (Jule Monique) and the volume was so low it was unusable.
Has anyone tried this?

 

[Bright Midnight]

I don't really see what you're doing here. Can you explain what you're trying?

 

[redtomfunk]

Hi,
A common thing I and mann toger have done om other amps. This is what the signal chain look like:
Bass -> external preamp -> effects return of Eich T500 amp

but I get very low volume

If it works well will other preamps, I would ask the question on the Monique thread, but it's surprising because the Line Level output signal is very hot. Did you pull and maxed the Line Level knob of Monique?

 

[redtomfunk]

I will try with other preamps but my guess is it is the Eich that is the problem

Trouble is there are preamps and preamps. A 'proper' preamp boosts the signal quite considerably to line level, but other preamps could be said to be more on the lines of sophisticated tone controls and put out no more signal than an instrument would. I couldn't find any specs on the Jules website to see which category it comes into.

I run Monique into the effect return of my Forte and have tons of power.

According to the manual you’re doing it right.
Bad cable, perhaps?

A Jule Monique is very much a “proper” preamp, among the most sought after high-end preamps available today. They are built to run as preamps in front of power amps, though they have nice DIs too.

Something might be going on with this one. I’d suggest two things:

Run another preamp into your Eich in the same manner to rule out the effects return there as the issue. Maybe you already have.

(oh, and try it with a different cable too.)

Where do you have the master volume set on the amp?

 

[redtomfunk]

Max

Is the loop switchable to parallel? Is so, this could be the issue.

Are you using a TS cable or TRS? On some effects returns, TRS can be an issue if the ring floats.

 

[redtomfunk]

I am using a normal jack not a TRS. Actually the same jack I use as I go in the normal input

Probably it’s Eich. I’m using Eich T300 and I’ve tried to run my Grace Design Felix into FX return and it was much quieter than it should be. So after Felix I just use regular input and everything flat on amp’s EQ. Sounds good.

I'd ask Thomas Eich directly. I haven't done it myself but heard of good customer service...

Monique has two outputs and two output level controls. One output is intended to function as a DI and the other is intended to function as line out. To push a power amp, use the Line out and the Line Level control.

These specs are from a review I found online:

I believe most Moniques have a pull switch on the Line Level control. If you need a hotter signal pull the control out. Per the specs above, this changes the line output level from 0dB to +10dB

The Sensitivity control should also pull out for more gain. I like both controls out.

Per the Eich T500 OM, the effects return is 10K ohms with a 0dB sensitivity.

If you can, try another preamp with the Eich. If it works fine, then the Monique is either not patched correctly, not adjusted correctly, or something is wrong with it. Could be a bad tube. Or it could be something else.

That's exactly what I meant in my comment, but much better explained. From what I know and my experience of Monique, I can see no reason why you can't have enough volume if you pull the Line Level knob - except if you have an issue with the Eich itself.

@redtomfunk Did you try with the Line Level knob pulled?

 

[redtomfunk]

My Monique is an early one without a line level pull knob

Ok. In that case, I don't have the technical skill to say if it's normal or not.
But with the 2 amps I own (Quilter BB800 and Jad Freer Sisma), I never have to pull the knob, and even like that I never go beyond 9 o'clock.

Did you ask to Jule and Eich support?

Perhaps @juledude will provide specifics on the line output level.
