PE-505

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

唱机放大器
采用双单声道全平衡输入/输出电路设计

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.

该产品PE-505是一个唱机均衡放大器与双单声道和全平衡输入/输出电路，支持平衡的MC输入。
开发的PE-505是通过依靠TEAC的音频技术专长，专注于录音和播放，目的是准确地再现录音制作者的原始意图。该PE-505将放大甚至非常微弱的音频信号拾取的唱头，处理他们没有着色，然后交付他们忠实，以保持尽可能接近原来的声音，在它被刻在主光盘上之前播放。
支持高精度RIAA校正电路，以及DECCA和COLUMBIA曲线。此外，还提供了可选择的MC唱头负载电阻和MM唱头负载容量；允许用户优化所使用的唱头类型和唱片条件的设置。

FEATURES

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.

全平衡电路设计

从头放大器到均衡放大器部分的缓冲放大器部分的最后输出级，PE-505采用了充分平衡的电路设计，在所有阶段，放大，均衡，并保持信号纯度，即使是最微弱的音频信号从一个唱头。
即使是非平衡的信号，在传统的RCA输入转换到差分处理模式后，输入端。

Equalizing circuit on the differential cartridge outp

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.

差动盒输出上的均衡电路

在均衡输出上吸收误差，差分输出均衡电路提供更准确的音频信号。差动输出电路，交叉倍增的热和冷输出彼此。其结果是，这两个信号被均衡为一个纯粹的和自然的音频信号交付。

High-precision RIAA circuit

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

高精度RIAA电路

一种新研制的NF型均衡放大器实现了小于±0.05dB的RIAA偏差。(20Hz 至 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.
*1 MM   *2 MC   *3 XLR input

高信噪比

该PE-505实现了106dB的RCA输入*¹，和86dB上的XLR输入*²，而剩馀噪声电压在MM上达到10μV，在MC*³上达到85μV
*1 MM   *2 MC   *3 XLR输入

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.

高精度旧式均衡曲线

除了现代的RIAA曲线之外，还支持1955年定义RIAA曲线之前由DECCA和COLUMBIA发布的单声道唱片上的单个曲线

Versatile settings and unique measuring functions

多功能设置和独特的测量功能

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.

505配备可切换的负载能力的MM唱头和可切换的负载电阻为MC唱头。此外，负载电阻测量功能允许用户通过在前面板上按MEASURE键来选择合适的负载电阻，以显示包括电缆电阻在内的总负载电阻值。
此外，亚音速功能显示亚音速信号小于6Hz的规范，而亚音速滤波器（17Hz，–24dB/八度）削减不必要的低频听力范围外

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.

DEMAG功能刷新唱头

具有快速退磁功能，磁芯和升压变压器的磁化铁芯均经DEMAG位30秒回放黑胶唱片来去磁。
