Battery Powered Stereo Preamplifier
The revolutionary battery powered 776 straight line preamplifier is strictly for the purist, paying particular attention to the all important role of the power supply.
This design ensures zero mains induced hum, very low impedance as seen by the amplifier throughout the audio spectrum and an excellent inter channel power supply rejection.
A true RIAA equalisation curve is followed to within 0.2dB accuracy (as against arbitrary roll offs) to ensure phase accuracy at low frequencies. The phono stage overall feedback is kept to less than 10dB at 20Hz to minimise dynamically induced distortions while maintaining the noise level at below -80dB.
Special attention has been given to the quality of the components, the effect of switches and connectors, etc and their behavioural changes with temperature and ageing. Therefore, near military grade components have been used throughout and it is manufactured in an extravagant sculptured solid aluminium casing.
Frequency response: 20Hz to 20kHz
Total harmonic distortion: 0.05%
Input sensitivity: 2mV (MM), 100mV (line)
Signal to noise ratio: 80dB (MM), 95dB (line)
Output: 1V (Pre out), 11V (Pre out Max)
