Extremly transparent, truest instrument preamp / DI
Deliver your tone without coloration. Hear unvailed tone produced by your instruments and play
Pure and transparent sound
SP-DI500 uses less than 1/3 of components compared to standard preamps. SP-DI500 utilizes only finest components such as feedback resisters that are more expensive than standard tip resistors. We strictly pay a closest attention on every tiny detail to keep signal uncolored. It featurs flat frequncey response even lower than 1Hz and higher and 300kHz. Ultra low end produced by synth bass, 5 string base are delivered as they sound.
3 step Input impedance Selector ( 2M, 100k, 10k)
Input impedace has 3 options to optimize to the souce instrument from vintage bass guitars with passive pick up to synthsizer with high output etc. Also, can add character with chosing an impedance.
Hi-Cut filter for balanced output ( OFF, 2kHz - 24kHz)
Hi cut filter reduce noise heard in high-frequency such as string nosie. Cut of frequency can be set from 2kHz to 24kHz.
3dB step gain selector
Gain selectors with fixed resistors for each gain settiings are used for audio quality in stead of potentiometers which degrades sound.
- ・33dB of gain ( balanced )
- ・Input impedance Selector ( 2M, 100k, 10k)
- ・3dB step gain selector with fixed resistors
- ・No coloration even ultra low end for bass instruments
- ・Hi-Cut filter for balanced output ( OFF, 2kHz - 24kHz)
- ・Unbalanced output to instrument amp ( Gain: 0dB, +6dB, +12dB)
- ・Instrument input on front panel ( Priority )
- ・Perfect equality between hot and cold of balacnce output signals
- ・Best for direct recording for bass, syntheizer, synth bass, guitar etc

SP-MP SERIES USER STORIES
Recording Engineer/ Grammy Winner
The sound is absolutely transparent and it is the kind of pre-amp you’d use when you want no coloration and you want to hear EXACTLY what comes in, without any kind of alteration of the sound, without any added sonic characteristics, basically the TRUE sound that is being picked up by your microphones
Recording Engineer/ Producer / Grammy Winner
My initial impression was a very good one. The sound is clean, clear and transparent, but with a nice punch. It’s a welcome addition to the world of first-class microphone preamps.
