DENON PMA-700Z ขาย 12,000 บาท
The power amplifier section uses a 2-stage Darlington pure complimentary
service direct-coupled 2-power supply OCL circuit.
DC stability and balance are required for all stages
of OCL circuit and complimentary service circuit. However,
PMA-700Z uses two differential amplifiers in the driver section to
increase DC control capability and obtain stability. In addition,
all stages of OCL improve low-frequency characteristics. Especially,
output impedance is less than 0.16 Ω from ultra-low frequency to 10 kHz.
