Z-TONE DI

Specs

Z-TONE DI Specifications

Topology

Ultra low noise, high bandwidth and ultra low distortion direct box, preamp and buffer, with variable gain and input impedance. Transformer-based galvanically isolated balanced output and electronically buffered low impedance unbalanced output. PURE and JFET input stages for total transparency or added harmonics.

Audio specs

I/O Gain: Unitary, from 1/4” input JACK to both 1/4” and XLR outputs when GAIN is at 0dB and Z-TONE at the SHARP position.
Gain Range: From -8dB to +8dB
Input impedance - Z-TONE set on PASSIVE mode: Variable from 1MΩ down to 2.2kΩ
Input impedance - Z-TONE set on ACTIVE mode: Approx 20kΩ
Output impedance, unbalanced out: 56Ω
Output impedance, balanced out: 600Ω
Max input level before clipping: +13dBm when powered by 48V phantom,+9dBm when powered by 9V battery
PAD: -20dB
Dynamic Range: better than 114dB(A) for both outputs, input gain at 0dB
Total Harmonic Distortion, balanced output, 1kHz, +4dBm input: 0.0033% (PURE), 0.2% (JFET)
Total Harmonic Distortion, unbalanced output, 1kHz, +4dBm input: 0.00055% (PURE), 0.2% (JFET)
