“Real-Sound” Phono Equalizer
REQ-S1EX
- A phono equalizer with extremely simple circuit configuration making
full use of the latent ability of latest operational amps close to the ideal
amplifier.
- Most important portion of the high gain amplifier circuitry like as phono EQ ,
the initial stage receiving the output from a cartridge incorporates separate
operational amps, most suitable for MC and MM cartridges for seeking
highest sound quality of each types.
- An ultra low-noise, high-gain “bipolar-input operational amp” is used for
MC cartridges with low-voltage, low-impedance outputs, while a high input
impedance and high-performance audio circuitry “FET-input operational amp”
is used for MM cartridges with high-voltage, high impedance outputs.
“CR Equalizer” in Pursuit of “Real-Sound”
Faithful Reproduction of Rich Information
Contained in Analog Vinyl LPs
- Thanks to the latest ultra low-noise, high-gain operational amps, we could adopt “CR equalizer”,
it has basically a minimum number of exclusively passive devices and excellent phase characteristics.
- Because of its simple circuit configuration, the sound
character of each passive devices used in the CR equalizer determines the final sound quality of the phono equalizer.
- REQ-S1EX employs two types of highest quality
“oil filled capacitor” custom-made by Arizona Capacitors, Inc. featuring different tonal character and “mica capacitors” with ultimate sound quality.
- They contribute to the straight, highly transparent, information-rich sound quality of the “Real-Sound phono equalizer”.
