The headphone amplifier, in addition to semi-conductor elements, uses 2 low-noise E180F / 6SCH9P pentodes, and an ECC82 vacuum triode.
The Vincent KXB-200 external headphone amplifier was created in collaboration with engineer Frank Blöhbau. The scheme of the amplifier is compatible with almost all headphones. In addition to a 6.3mm headphone jack, the KXB-200 also has a 4-pin XLR connector.
KXB-200 fulfills the frequency range: 20 Hz – 20 kHz with unevenness of ± 0.1 dB and harmonic distortion not worse than 0.01% at a frequency of 1 kHz, power 0.1 W and load impedance 32 Ohm.
This achieved a signal-to-noise ratio of> 95 dB. There are three headphone gain modes with different impedances: nominal, low and high.
KXB-200 is equipped with outputs: 1 x stereo RCA (PRE OUT), 1 x stereo RCA (REC OUT), 1 x stereo headphone jack 6, 3 mm, 1 x Headphene XLR, 4-pin stereo. The built-in power supply unit operates with voltages of 230 V / 50 Hz or 115 V / 50/60 Hz. The body of the amplifier can be black or silver.
