I have a new DGX. My problem is when I want to add a dual voice to the piano. I press the portable grand button then hold the dual button till the violin voice appears then select the voice I want and...


HI, Let me answer the question.

1) Select the DUAL VOICE (not portable grand ) button and hold for longer than 1 second.

The choose voices required.

If you press the Portable Grand button this resets the keyboard top a piano.

I hope this helps

Our sound system runs two separate xl 5000 crowns individually to 2 srx728 subs(2241hpl speakers). Amps are run bridged and have been connected to "discrete" inputs on cabinets (I think this is...


More than likely you have lost the speakers... You sent TOO much power to them and likely the voice coils have heated and distorted and are rubbing the pole pieces and hanging up on them. If the voice coils now short some of the windings, next you will lose your amps as well. If you can access the cones, you can try gently moving them in and out with your fingers and you can feel the voice coils rubbing sometimes. REMEMBER ALWAYS check the RMS rating of the speakers against the RMS ratings of the amps... DO NOT fall for the "advertising" things of "peak power" and "program power" ratings... these numbers are to sell equipment... Use RMS continuous ratings when sizing amps to speakers. Typically the RMS continuous ratings are 1/3 of the peak or 1/2 of the program ratings. You will find amplifiers rated either way so you have to dig out the real ratings. In bridged mode the full output of both halves of the amp work together. Your speakers are rated at 1600 Watts continuous... I am not sure I believe that number even... you would be deaf in front of that quickly... Your amps appear to deliver 5000 Watts RMS in bridged mode... over three times what the speaker is rated at. Since you have the amps, set one aside and run each speaker from one side of a single amp NOT using full gain AFTER you get the speakers re-coned. I would recommend putting a fuse in the speaker lead to HELP protect the speakers when repaired.

Gemini gvx 15, were is the fuse located, we can't find in nor inside or outside ?


It may NOT have a fuse. If too much power was sent or an amplifier drove DC to the speaker, the voice coil may have fried. The specs do NOT brag aboput protection, so it is likely either the speaker is blown or the internal wiring is broken. Open the unit and use an ophmmeter to tesst the speakers.

I am trying to record sounds from my keyboard into my MPC 1000. I have what I think is the proper set-up. MIDI sync...softthru as track...etc. Problem is when I set it up I can play one sound and record...


It is not clear whether you are recording audio or MIDI. If you recorded Audio samples, you will get the same sounds back even if you change the voice on the keyboard.

If you record a MIDI sequence, and then play it back you will STILL get the same sounds UNLESS you also record the MIDI voice or patch changes so the voice is changed as it occured when you recorded it. Usually there are options taht you can enable or disable voice changes.

Faurite buttons bushed there is a quarter note gap in sound in juno di how can i solve


Not sure what you mean by "buttons". IF you are trying to change voices, a lag between sounding of the old and new voice can be expected as the generators within the synth are reconfigured for the new voice. This is a lower-end synth and as a result doesn't haved the performance of some of the newer ones.

If the lag is just between notes that are being keyed using the same voice, that is too much delay and something is probably set wrong.

Does this Karaoke Mixing Amp have voice cancel


The short answer is NO, it does not... BUT you should understand what MOST voice cancellers do. ESSENTIALLY they ASSUME that the vocalist is centered betweeen the stereo recording mics. The "voice cancellor" merely subtracts the left and right signal which REDUCES the voice from the center of the stage. Frankly, it doesn't work all that well. Somee typicall leaks through and often is garbled.
For Karaoke you best stay with media that already has vocals stripped from it.

My Rocker 30 has been working just fine up until now. I go to turn on the amp and I get no sound whatsoever. The tubes and ht fuse are fine. I've looked at some forums online and they say the fuse might be...


Apparently you have tested the tubes on a tester and usually there is a pilot light that would not be lit if fuse was blown.

Common problems are bad jacks and switch contacts on power amp INPUT or INSERT jacks. Also circuit board cracks and bad solder joints are fairly common, especially where volume controls attach to the circuit boards.

More expensive things are things like fried speaker if volume was played too loud. An ohmmeter test of the speaker would tell if the voice coil has blown.

Casio tonebank ct700 no sound from chords only whilest on fingered chord please advise


More info. If you are chording on the left half of the keyboard, SOMETIMES they allocate or have the option to select a different voice for the part where chords are played. For these, you have to ALSO select a voice for that half of the keyboard. If you don't select a voice, then you would not have anything sounding.
