상품 상세설명




"DSP" 사운드웹 시스템의 메인 컴포넌트로서 8개의 입출력을 가지고 있으며 아날로그 입출력인 경우

24bit/96kHz의 A/D D/A 컨버젼을 기본으로 하고 옵션으로 AES/EBU 디지털 입출력을 지원하고 있습니다.

내부에 장착된 DSP는 게인 컨트롤러 컴프레서나 게이트 등의 다이나믹 프로세서 딜레이 크로스오버 EQ 매트

릭스 믹서 등 모든 종류의 오디오 신호처리 프로세서들을 가지고 있어서 9088ii DSP 하나 만으로도 여러 가지 용

도의 오디오 시스템 구성할 수 있습니다.

두 개의 네트워크 포트를 통해 다른 9088ii나 9000ii와의 연결이 가능하고 CAT5 케이블을 사용하여 컨트롤 신호

와 8채널의 디지털 오디오 신호를 동시에 전달하도록 설계되었습니다.


The 9088iis Networked Signal Processor forms the heart of the Soundweb system. In a single rack

space unit it offers 8 analogue audio inputs 8 analogue audio outputs 200 MIPS of digital signal

processing a pair of network jacks and a variety of control options.

The front panel of the 9088iis has a number of LEDs to allow a quick view of activity on the audio inputs

and on the network. It also has a mini-DIN connector for an RS-232 serial port: this is normally used to

connect a PC for system setup and control.

The rear panel contains the audio inputs and outputs and the network jacks. It also contains a second

RS-232 port which is normally used for control from an external controller such as AMX or Crestron.

Finally it contains a control connector: see section 4 Control options for a description of how this is

used. Both control i/o and analogue i/o connections are made via "Phoenix" style two-part screw

terminals; the female connectors are shipped with the Soundweb unit so installation can be made with

no soldering and no extra connectors to buy.

The 9088iis contains two preamplifier cards for the analogue inputs: each card handles four of the

inputs. Three types of card are available: the analogue line card the analogue mic/line card and an

AES/EBU Digital Input/Output card.

The line card gives a choice of two gain settings: 0 dB and 12 dB (intended as a pro/consumer switch).

The mic/line card provides a range of gain settings from 0 dB to 72 dB together with phantom power

and phase reverse. In all cases each input can be switched individually.

The Digital input card holds two AES/EBU stereo inputs and outputs with input sample rates from 32kHz

to 96Khz. Output sample rates are user-selectable from 44.1kHz 48kHz 88.2kHz and 96kHz and an

external word-clock sync input is provided for house-reference.

The 9088iis device can be configured with digital and analogue mic or line input cards to specification.

The analogue outputs are equipped with analogue attenuation after the DAC

stage. If the unit is used at anything lower than its full output level it makes sense to apply the final gain

reduction in the analogue domain: in this way the DAC noise is also attenuated and the signal to noise

ratio is kept at a maximum.

The core of the 9088iis contains two Motorola 56303 DSP chips running at 100MHz each and thus

providing a total of 200 MIPS of DSP. There is also a block of dynamic RAM allowing a total of 11

seconds of audio delay. The main control processor is a Motorola 68000-series CPU which runs a

real-time multi-tasking operating system; this CPU takes care of system operation and interfacing and

performs all the necessary housekeeping functions. Finally the core contains a flash EPROM (see

section 5 Flash EPROM storage) in which is stored all of the software to run the unit and also the unit"s
