Profono
Phono Amp.
Summary
고품질 아날로그 포노 앰프 Profono는 포노(Phono)단계가 내장되어 있지 않거나 포노(Phono) 스테이지의 품질이 낮을 경우 프리앰프 앞에 설치되는 고품질 아날로그 턴테이블 카트리지 앰프입니다. 향상된 사운드와 다이나믹 및 좀 더 뛰어난 디테일을 위해 톤암 케이블을 Profono에 연결 한 다음 RCA 인터 커넥터 케이블을 사용하여 프리앰프 또는 인티 앰프의 보조 장치에 연결하십시오.
 
Product Infomation  

Overview

High quality analogue phono amplifier

Profono is a discrete high quality analogue turntable cartridge amplifier which is installed before your pre-amp or integrated if you do not have a built in phono stage, or if the phono stage is of low quality. For improved sound, dynamics and a greater detailed performance connect your tone arm cable directly to Profono, and then connect to the auxiliary of your pre-amp or integrated amp using RCA inter connecting cables.



Features

  • Fully adjustable/customised cartridge loading system
  • Moving coil low, high settings and moving magnet
  • Multi functional earth connection point
  • Solid RFI resistant case, 170 x 80 x 50mm (L x W x H)
  • Optional high quality power supply for upgrading later



Design

Profono

Profono is designed and built to be a genuinely high-end phono preamplifier delivered at a highly competitive price point, able to compete with – and even outperform – models at twice the cost. Carefully selected premium-grade components and materials are used throughout – for example, the cheap ‘dip switches’ found in lesser phono stages are replaced by a series of shunt resistors to set cartridge impedance. This is a better quality solution than capacitance loading switches, which tend to be cheap and affect the purity of the signal, in addition to being an entrance point for RFI (Radio Frequency Interference).

Compact in size and sturdily built, Profono sports a cleverly designed all-aluminium case, with individual corner extrusions holding the aluminium panels together, ensuring a tight, rigid and reliable construction that is quick and efficient to manufacture. Casework of such quality is rare at this price point and serves to protect the internal components, reject sonically deleterious RFI and keep the unit solidly in position when heavy cables are connected.

To minimise noise and distortion, the Profono’s power supply unit (PSU) is housed separately and connected via a detachable cable. PSU upgrade options will be available at a later date, for those who wish to attain an even higher level of performance. A switch on the Profono’s rear panel gives three settings for cartridge gain: moving coil low (50dB), moving coil high (61dB) and moving magnet (41dB). Offering two moving coil gain settings is unusual for a sub-£1,000 phono preamp and ensures optimal performance with an extensive range of phono cartridges. The net result is a high performance yet affordable phono preamplifier that delivers wide compatibility and class-leading sound quality in a simple, convenient package.
