PA series (이동용 시스템)는 작은 규모의 각종 음악, 스피치, 회의 등의 행사에 적용할 수 있는 렌탈·이벤트 믹서입니다. 이 시리즈는 이동을 쉽게할 수 있는 툴과 다양한 행사에서 잘 운용할 수 있는 기능들로 설계되었습니다.
* 특징
· 고품질 음질의 Mic pre-Amp 회로 채택 : Low noise, 헤드룸의 증가
· parametric (파라메트릭) 방식의 EQ : output 섹션에 위치하여 룸의 이퀄라이제이션을 할 수 있도록 하며, 특정 주파수를 조정하여 PA시스템의 마이크 하울링 현상을 제어
· 각각의 mono input 채널 (마이크 입력) : 100Hz 이상의 High-pass filter가 장착되어 있으므로 불필요한 저음이 들어가지 않게 되어 깨끗한 음질을 확보
· SPDIF 포맷의 디지털 시그널 아웃 (RCA 잭) : 디지털 기술이 적용된 레코딩 기계에 신호를 보내거나 녹음 가능 (L.R)
예) PC의 사운드 카드, DAT, Digital Audio Processors
· 4-pin XLR 타입의 Lamp 소켓
· All 100mm Long Fader 장착
· 4 band EQ
· 4 Aux : 2개의 pre-fader (FB1, 2), 1개의 post fader (FX), 1개의 post fader (Aux out))
· 2 stereo input (RCA 타입과 TRS 잭 2종류 함께)
· Phantom 전원 : 각 채널에 위치
· Digital FX(효과) : 16개의 프로그램 내장
· 12개의 LED로 Output metering
· Output 부분에 파라메트릭 4 band EQ 장착 (output A, B에만 적용)
· Output : main (L, R) 2 CH - 1개의 페이더
· Powered option 기종 중 PA12-CP, PA20-CP는 파워 앰프 (500W + 500W / 4ohm)가 내장된 기종

Rackmount (W x H x D, kg) |

| Mono inputs |
| 8 mono channels with Mic [XLR] & Line [TRS] inputs. Line input overrides the XLR input. Individual +48V phantom power switches are provided. New padless two-stage preamp with smooth gain law. Line input goes to second stage for better matching and performance. Switched 100Hz high pass filter. Insert point. 4 band EQ. 4 aux mixes. Mute with LED. PFL button with LED [functions as peak indicator]. 100mm fader. |
| 4 Band EQ |
| Shelving LF [60Hz], and HF [12kHz]. Fixed LM [250Hz], and swept HM [300Hz - 6kHz]. The fixed 250Hz control has been carefully selected to provide reduction of ‘muddy’ sounds and enhance ‘warmth’ |
| Dual Stereo Channels | |
| Two stereo channels with two unbalanced stereo inputs on each. One is RCA one is TRS jack. Independent gain controls provide source mixing in the channel strip. The top inputs [RCA] can be switched direct to L&R instead of the channel strip providing extra returns. Two band shelving EQ. 4 aux mixes. Stereo balance, mute with LED, PFL with LED, and 100mm fader as mono channels. | |
|
| 4 Auxiliary Sends |
| From all channels: 2 pre-fade for foldback mixes - these have 100mm fader masters, mute switch with LED, AFL with LED, and TRS outputs [can be routed internally to output section]. 1 post-fade aux mix for FX - this feeds the internal FX and has a TRS jack output for external FX. 1 post-fade aux mix to TRS jack output is provided for external FX or special feeds. |
| Output EQ |
| 4 band semi-parametric EQ is provided in the output section, this affects the TRS slave outputs, and the internal constant power amplifiers. This offers more control than graphic equalisers for precise management of speakers, especially foldback / monitors. Source selector allows output EQ section to be used on Left / right, L&R sum / foldback1, or foldback1 / foldback2. |
 |
| Constant Power Amplifiers | |
| 1kW i.e. 2 x 500W RMS peak power professional class AB power amplifiers built in. Unique ALLEN&HEATH design gives full output into 4 OR 8 ohms [rear switch selector]. Output is to locking Speakon™ connectors. Thermal management twin fan system. Full protection - input limiter to prevent clipping, short circuit protection, current limit and DC fault sensing. LED indication of: signal presence, peak warning, speaker protect and temperature. AB amp input TRS break-jacks [normalised to output section / slave out jacks] allow independent use of the power amplifiers if desired. Standby mode switch puts amplifier into protect with speakers isolated. | |
|
| Digital FX | |
| 16 program digital FX processor provides reverbs, delays, chorus and others, inc combined. This FX module takes its feed from the post-fade FX aux on the mono & stereo channels. The output of the FX module is controlled by a 100mm fader with mute & PFL and is routed to the stereo mix and FB1&2 with post fade level controls. At this point, 2 TRS inputs with level control provide a way of combining external FX with the internal unit. Internal FX unit can be switched off to use external only if preferred. A footswitch TRS jack is provided to mute the FX channel. | |
|
| Master Section | |
| Background music BGM mode - plays 2 track input into the main mix post fader, allows user to pull down fader (whilst patching, taking a break, or during walk-in) and leave music playing through the amplifiers / speakers. 2 track input [RCA] with level control to L&R - feeds headphone monitor selector [checking recording]. Twin, 3 colour 12 segment LED meter displays active monitor source. Large LED indicates PFL / AFL active - signal overrides L&R / 2TRK monitor source selection. Standby switch uses relays to disconnect the speakers. 2 track output [RCA] analogue + SPDIF allows direct to digital recording. Switchable pre / post master L&R fader. Mono sum out with level [TRS] - mode switch to provide sub feed with 100Hz low pass filter. Phones out [TRS] with level. | |
