Roland TD-07 KVX

[Purdie Shuffle]

I’m trying to figure out a way to get my Roland TD-07 to play through my Vox amp. Everything is working fine amp and the drum kit but no sound is coming from the amplifier. Not sure what I’m doing wrong.

Anybody have any suggestions?

I’m thinking that I might have posted this in the wrong section of the site. If so sorry.

What sort of Vox amp?

 

[wolfereeno]

Do you hear sound if you use headphones?

Does the amp work?

 

[jaybeez]

Can you post a picture of the back side of your module and the amp you're using?

What sort of Vox amp?

Vox valvetronics. Has a tube section along with all the digital crapolla. I’m thinking I need a dedicated drum amp/monitor.

Do you hear sound if you use headphones?

Does the amp work?

Yes. Headphones work great. I’m thinking it isn’t a powered output.

No I have all kinds of problems posting photos to the forum from my iPhone.

The module is the new TD-07

without a picture this is going to be tough, but can you describe how many “black lines” you have on each end of the cable you’re using?

This cable has 2 black lines per end:

This cable has one black line per end:

The Valvetronics is a guitar amplifier and its inputs are expecting a high impedance low output signal from a guitar. Your eKit will be outputting a line level signal, so will not sound good going into the input of your guitar amp. You could build a pad cable, but yeah nah. If it has Line Out / Line In on the back, you may get away with plugging the eKit into the Line In.

But, even if you get it "work" ... it will likely still sound pretty bad. The whole thing, including the speaker, is designed for guitar.

You would be much better off to get a Keyboard amp or a powered PA speaker, something with a fair bit of power for head room, and for it to be able to accurately recreate the full frequency spectrum.

If you get a powered PA speaker, with a small inbuilt mixer, you'll be able to rock out with your mates, when they come over.

Agreed. guitar amps sound terrible for drums. Maybe a bass amp, definitely a keyboard amp.

You could always try going from the headphone out to the amp if the signal is too low. Probably would need to turn the headphone volume down a bit.

Thank you your response was helpful. I suspected as much on my own.

Anybody want to buy a guitar amp? (Grin)

This isn’t really true. Your existing setup should work fine. The Valvetronix Amps have “aux in” inputs, stereo jack. So if you connect your Roland stereo “output” jack to your amp “aux in” it should work OK. Turn volume of both drum machine and amp down to minimum, then raise slowly while hitting a pad to get a good level.

It is true that this won’t work especially well at high volume, since amp designed to work best for mid and high frequencies, and your drums can overload the amp especially at low frequencies. But by all means get your current setup working before you decide what if anything to upgrade.

If you are getting no sound at all, likely to be a faulty cable. Debug by hooking up a different sound source to your amp, like an iPad, phone, cd player etc.

Thank you. This is why I have always loved this forum. Most knowledgeable members anywhere.

Yes, good news is that the amp has an aux-in.

Keen to hear how it sounds.

Its not that a guitar amp wouldn't work, it's that they rarely sound good for drums.

They aren't built for the lows of drums and highs of cymbals. They're built for guitars to sound good, which often means distortion as well as midrange-centric frequency response.

I bet a lot of us have guitar player friends who are the benefactors of this lesson! I had the loveliest Roland cube amp. Sounded like total sh*t for my purposes but my friend loves it.
