and Q39 'turned ON' consequently and the muting operation obtained.
ii. (3) :NOTE
I l Care should be taken not to decreasa a closed loop gain less 20dB cause
parasitic oscillation.
'. The maximum allowable input voltage is 300 mVrms not to increase the input
vintage above this value for stable operation.
