Phono equalizing amplifier
with dual monaural and fully-balanced input/output circuit design

From the head amplifier to the equalizing amplifier sections to the buffer amplifier section on the final output stage; the PE-505 employs a fully-balanced circuit design throughout all stages that amplifies, equalizes, and maintains signal purity of even the most extremely faint audio signals picked up by a cartridge.
Even unbalanced signal on the conventional RCA input is converted to the differential processing mode right after the input terminals.

Absorbing errors on the balanced output, the differential output equalizing circuit delivers a more accurate audio signal. The differential output circuit that cross-multiplied the hot and cold outputs each other. As the result, both signals are equalized for a pure and natural audio signal delivery.

A newly developed NF-type equalizing amplifier achieves less than ±0.05dB of RIAA deviation.

High-precision RIAA circuit
A newly developed NF-type equalizing amplifier achieves less than ±0.05dB of RIAA deviation.
(20Hz to 20kHz)

High Signal-to-Noise ratio
The PE-505 achieves 106dB on the RCA input*1, and 86dB on the XLR input*2, while the residual noise voltage reaches 10μV on the MM and 85μV on the MC*3 which are sophisticated.
