Sunrise S-TI Tube Interface and Flight Case
The Sunrise Tube Interface is an all vacuum tube, transformerless, high resolution line amplifier. The STI reveals nuance, detail and openness with a quality usually reservered for only the finest studio microphones. Reproducing the natural voice of an acoustic guitar in the studio with only a microphone has been surpassed by the Sunrise Pickup and STI, which has become the highest standard of the industry for both live performances and recording.
The Sunrise Tube Interface delivers +20 dB of gain, and has two unbalanced outputs (XLR and 1/4") with headroom in excess of +30dBv. This Tube Preamp will deliver the sonic quality and resonance of the instrument being amplified. Frequency response is flat from 2Hz to 50kHz + or - 1 dB. The two 1/4" input jacks are in parallel with an input impedance greater than 2.0 megohm to insure against pickup loading. A true 600 ohm output impedance will drive extremely long cable runs without signal degradation.
