Notes:
1. The (+) polarity of DC block capacitor installed in the I/O pin of the PT2307 should face towards the
higher potential.
2. HP_SENSE (Pin 23) must be connected to Pin22 LOUT.
3. The gain setting resistors (R3, R4, RL1, RL2, RR1, RR2) should keep as close as possible with the
PT2307 chip to prevent pick-up noises.
4. DO NOT CONNECT HEADPHONE COMMON (VEE) TO OTHER AUDIO EQUIPMENT! THIS
MAY CAUSE IC DAMAGE.
