Product overview
The PE-505 is a phono equalizing amplifier with dual monaural and fully-balanced input/output
circuits that support balanced MC input.
The development of the PE-505 was achieved by relying on TEAC’s audio technology expertise,
focusing on recording and playback, with the goal of accurately reproducing the original intent of the
recording producers. The PE-505 will amplify even very faint audio signals picked up by the
cartridge, process them without coloration, and then deliver them faithfully in order to keep the
listener as close as possible to the original sound that was played before it was engraved on the
master disc.
The high precision RIAA correction circuit, as well as both DECCA and COLUMBIA curves are
supported. In addition, selectable load resistance for MC cartridges and load capacity for MM
cartridges are present; allowing users to optimize the settings for the type of cartridge used and for
the condition of the record.
Fully-balanced 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.
Equalizing circuit on the differential cartridge output
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.
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 (MM), and 86dB on the XLR input (MC), while the
residual noise voltage reaches 10μV on the MM and 85μV on the MC (XLR) which are sophisticated.
High-precision OLD EQ curves
As well as the modern RIAA curve, individual curves on monaural records from DECCA and
COLUMBIA issued before the RIAA curve was defined in 1955 are also supported.
Versatile settings and unique measuring functions
The PE-505 equips switchable load-capacity for MM cartridges and switchable
load-resistance for MC cartridges. Furthermore, the load-resistance measuring
function allows users to select an appropriate load-resistance by pressing the

MEASURE key on the front panel to show the total load-resistance value including cable resistance on
the gauge.
Also, the Subsonic function shows subsonic signals less than 6Hz on the gauge, while the subsonic
filter (17Hz, -24dB/octave) cuts unnecessary low frequency out of the hearing range.
DEMAG function to refresh the cartridges
With the quick demagnetize function, both magnetized iron cores of MC cartridges and the step-up
transformer are demagnetized by playing back a vinyl record for as short as 30 seconds with the
DEMAG position.
