Very low volume on all drums.

There is probably both a global volume and individual program violume as well. One or both may have reset to a lower level and need to be turned up. It's also possible that the general output has a setting for line level or instrument level, which may be software controlled. Take a look through your manual to find these settings and adjust to suit.If all else fails, contact Roland Customer Service at this link for help.

Hi, I can help you with your question. On the face of the effects, towards the right side, there are three settings that can be adjusted: DRIVE, TONE and VOLUME. The VOLUME knob is your master volume. The expression pedal can adjust volume, but it's output volume is controlled by the master VOLUME knob we just identified. I hope this has helped you, and if it has, could you please click on the "helpful" button ? Thank you!

Hi, With my sound engineers hat on I would use a small PA. mixer, amp and speakers!!!!
For quality you need a full, flat frequency range system with good headroom.
I assume this is for your own listening, when using an acoustic kit?
There are one box solutions.

1. Drum amps. Like a monitor wedge with an amp, Roland do a PM-10, Various other makes are available.
2. General purpose powered wedge.
3. Keyboard Amp, these are full range and available in various sizes.
4. Bass amp with high frequency driver (tweeter), not the best but will have good bottom end.
5. Powered or active speaker, much like a powered wedge, but a different shape, needs an input volume control.

All these systems need to have large bass units, 10 inch minimum, and will be in mono. Two will give you stereo,
How loud depends primarily on the sensitivity of the speaker. But manufactures insist on selling things by power. Worth looking this up.
At a couple of feet away, 20 watts should do it, with high sensitivity speakers, more likely you find most things as above start at about 70 Watts.
Good luck, I hope I have widened you choices a bit.
All the best, Chris the Fader.

First plug a set of headphones into the Left audio out and see if you get any sound from there... NOTE: it will only be in the left headset and this is normal. Turn up volume control... note the level will be low as this is a line output, not headset. This is a test to see if there is audio.

You left off the one bit of info we need... however, make sure the volume control on the keyboard is around the halfway point... If it is way down, turn it up and reduce the channel volume knob some. Make sure the cable from the keyboard is an instrument rated interconnect and not one intended for speaker (usually marked as such). Make sure the keyboard AND this amp are powered from the SAME receptacle... even if you have to run an extension cord. Listen with headphones on your keyboard to make sure the sound is clean there.

If this ties to a keyboard, make sure the keyboard and this are BOTH plugged into the same receptacle. You should send a higher level from the keyboard (turn volume up to around 70% or so) and use less volume at the input gain of this amp. Use more at master volume if the amp has one if needed. If the hiss is there with NO input cables plugged in and input gains at 50%, that is objectionable, the amp probably needs servicing. Unused channel gains should be clear down.

The sound on all the stock kits I found to be too low. What I did was create a custom kit and altered the dynamics of all the pads and cymbals - once you're in the dynamics settings, just hit the pads/cymbals the hardest you normally would and save that setting!

Is volume at headphone normal? Does volume control vary the volume even though it might be low?
Has any internaal settings been changed before this happened? Has an accident happened involving the output cables?

There are 2 channels, Which means there are 2 sets of knobs ... One for clean and one for crunch. Start out with a low master volume and set up the crunch, Then the clen and switch between the 2 and make adjustments until they match volume wise ... Then turn the master up.
