After receiving my new SP in the mail and taking it on a test run, I'm experiencing that the output volume is extremely low and equally low is the quality. At the same time the audio is clipping, despite being extremely low, and this clipping shows on the "peak" led, on the sampler. So far I have tried to monitor the output through my interface and through a smaller external soundcard. I have also tried to change out the cables, but yet none of these have resolved the issue.

If any of you have any suggestions for a fix, I would be glad to hear them.
Thank you in advance!

Copied & Pasted this from page 39 of the manual.. there's a sticky thread in the S.P.I section of the forum if you don't have a copy.. maybe solves the problem if it isn't a faulty unit?


Adjusting the Input Gain

Here’s how to adjust the SP-404SX’s input gain .

MEMO If the PEAK indicator stays lit and it’s not possible to adjust the volume of your audio source device, set the SP-404SX’s input gain to “-10 dB .”

1. Hold.down.the.[FUNC].button.and.press.the.pad. [11].(.INPUT.GAIN) .

2. Turn.the.[CTRL.3].(LEVEL).knob.to.make.the. setting . The [REC] button will blink when you turn the knob . Range: -10 dB, 0 dB

3. Press.the.[REC].button.to.confi.rm.the.setting .

MEMO • If you decide to cancel, press the [CANCEL] button . • This setting is retained even while the power is turned off .

Adjusting the Output Gain

Here’s how to adjust the overall volume of the SP-404SX .

MEMO The SP-404SX has a maximum polyphony of twelve notes . There will be a major difference in the volume depending on whether one note or twelve notes are being produced . If you are playing only a few pads at a time, or if you have connected the SP-404SX to a DJ mixer or other device, and are using it as an eff ects processor, raising this internal processing level will allow you to output a higher level . If you are playing a larger number of pads simultaneously and the sound is distorting, you should lower this internal processing level .

1. Hold.down.the.[FUNC].button.and.press.the.pad. [12].(.OUTPUT.GAIN) .

2. Turn.the.[CTRL.3].(LEVEL).knob.to.adjust.the. setting . The [REC] button will blink when you turn the knob . Range: -3 dB, 0 dB, 3 dB, 6 dB, 9 dB, 12 dB

3. Press.the.[REC].button.to.confi.rm.the.setting . MEMO • If you decide to cancel, press the [CANCEL] button . • This setting is retained even while the power is turned off .

Yeah I've already tried both, but that doesn't rid the random clipping and the very poor audio quality. Thank you regardless, though. I'm going to contact the seller and sort something out, hopefully.
