*) GRAPHIC EQUALIZER

1. 개요

본 기기는 가청 주파수 음역대를 몇 개의 주파수 음역대로 분할하여, 각각의 음역대의 레벨을 슬라이드 볼륨으로 증감시킴으로써 주파수 특성을 조절하는 장치로 다음과 같은 규격에 준한다.

2. 기능 및 특성

Enhanced Proportional-Q equalisation provides both smooth contouring EQ and High-Q notches

Fixed 80 Hz high-pass and 12 kHz low-pass fi lters per channel with bypass switches

Long-throw 45 mm oil-damped faders with dust covers for increased accuracy and reliability Channel bypass switch

Power-off bypass relays

Electronically balanced inputs and outputs on both Neutrik* XLR and ¼" TRS connectors

Rugged 3U rackmount chassis for durability in portable applications

Auto-ranging universal switch-mode power supply
