Physical Specification
Very quickly, let us gloss over the specifications of the Bit88 device. The device implements a mix of componentry using both integrated circuits and vacuum tube technologies to achieve its intended enhancement effects.
- Input impedance 100K ohm
- Output loading Minimum 22K ohm
- Power consumption 3 watts average
- Frequency response 20 Hz – 20 KHz
- Signal coupling AC coupled
- Input signals 2V p-p
- Gain 1.6 @ 1 KHz square wave
- IC module supply +18V, -18V, supplied using 7818 and 7918
- 6DJ8/6922 supply +18V, -18V using 7818/19, +6V 0.3A using 7806
Also stated in the technical.pdf, 1388 Technology did not make excessive claims. The signal to noise ratio (SNR) measured just exceeds 85dB between a frequency response of 20Hz to 25kHz, tested at a more stringent -1dB point instead. Also stated is its high-input impedance of 100k ohms making it suitable for almost any source load.
