Extremly transparent, truest instrument preamp / DI
Green：Hot Red：Cold
Exactly identical between hot signal and cold sigmal from 1Hz to 4MHz and higher.
Positive and negative symmetry from 0V. No error in speed of rise and voltage value (output level).
This is a Instrument preamp / DI that delivers the wide bandwidth and ultra-fast response required in today's high-resolution recording environment.
Sound quality problems such as "unclear pitch" on basses with conventional DI are due to the lack of frequency bandwidth and response performance of the DI and preamp. This is more pronounced in the low frequencies and is a challenge for basses, especially multi-string basses and synth basses that produce low B and even lower G flat.
The SP-DI500 follows the technology of the SP-MP series of microphone preamplifiers, which are highly acclaimed by top engineers and creators for their excellent fidelity to the original sound with an extremely wide frequency response and ultra fast response in nanoseconds.
The ultra fast response and frequency response that covers not only low B (30.87Hz) and G flat (23.12Hz), but also the lowest note (16.35Hz) of 88-key pianos such as Bösendorfer Model 290 Imperial, one octave further down the range, produces clear, stable pitch and tight The high frequency range also covers the range of the instrument.
The high frequency response is also flat to 4 MHz, well beyond the range of musical instruments. Even sampling rates as high as 784 kHz can be faithfully converted to AD. Reproduces even the previously imperceptible resonance of strings. The original timbre of the instrument and the tones and nuances created by the player's performance can be recorded without any loss of expression."
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.
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 reduce noise heard in high-frequency such as string nosie. Cut of frequency can be set from 2kHz to 24kHz.
Gain selectors with fixed resistors for each gain settiings are used for audio quality in stead of potentiometers which degrades sound.
