■Inductor EQ

Rupert Neve가 디자인한 최초의 500 시리즈를 위한 인덕 EQ입니다. 551 EQ는 맞춤형 인덕터 주변에 제작되었으며 Neve의 클래식 EQ 모듈에서 가장 좋아하는 밴드를 기반으로합니다.

■Low EQ

+/- 15 dB Shelf 또는 Peak, 35 Hz, 60 Hz, 100 Hz 또는 220 Hz에서 선택 가능

■Mid EQ

+/- 15 dB (중심 주파수 6 개); 200 Hz, 350 Hz, 700 Hz, 1.5 kHz, 3 kHz 및 6 kHz, with High Peak switch to narrow the bandwidth (increase the Q) of the filter

■High Shelf

8 kHz 또는 16 kHz에서 +/- 15 dB shelf 또는 peak 선택 가능

■HPF

80 Hz 주파수가 고정된 12 dB / octave high pass filter

■Transformer I / O

Rupert의 맞춤형 트랜스포머를 기반으로 설계되었으며 특히 500 시리즈 포맷을 위해 설계되었습니다.
