RKV MARK 3 ultra highend headphone tube amplifier___________________
- CLIPPING / OVERLOAD circuit -
When the red sine wave at the output of the OPA reaches the upper or lower limit of supply voltage (out
of range), one of the two red LED ( green / blue wave ) lights as an indication of an overload of the
amplifier. Then either the volume is too high, impedance is mismatched, or a tube of this channel is
faulty.
