클래식 표준 - 매우 낮은 왜곡과 잡음 성능과 동시 이중 도메인 기능
2700 시리즈는 최고 성능, 가장 낮은 디스토션, 그리고 오디오 분석기에서 최고의 호환성을 필요로 하는 오디오 엔지니어를 위해 개발되었습니다. Programmable Serial Interface Adapter (PSIA)를 사용하여, 고품질 컨버터와 다른 칩 설계에 있어 최상의 솔루션입니다.
2722의 진정한 듀얼 도메인 구조는 아날로그와 디지털 신호 모두 완벽한 측정을 가능하게 해줍니다: 아날로그 제너레이터와 아날라이저 성능은 어떤 디지털 컨버터 기반의 설계보다 우수합니다. 한편 디지털 분석 기술은 정밀함의 광대한 배열, 다른 도메인에 대한 빠른 속도의 측정 기술을 제공합니다. 크로스 도메인은 두 영역을 완벽히 사용할 수 있게 해줍니다.
2700 시리즈의 일반적인 THD+N은 2.0Vrms에서 -115dB 이하입니다. 그러나 오디오 프리시즌이 엄격하게 규정한 THD+N 스펙은 –112 dB로서, 2700 시리즈는 의심할 여지가 없는 오디오 분석기의 리더입니다.

AP2700.exe is the control software for 2700 Series instruments. Running on the controlling PC, AP2700 is a powerful and sophisticated real-time interface, with hardware and software system modules and functions controlled using settings on virtual panels, and measurement results displayed in virtual meter and graph readings.
The 2700 Series offers an array of powerful, time-saving analysis tools to speed your testing procedures including, but not limited to: multitoned testing, harmonic distortion analysis, filter creation and more.
The 2700 Series offers both AES3 and IEC60958 serial digital interfaces, with fully configurable serial data and clock ports available via the auxiliary PSIA-2722 Programmable Serial Interface Adapter.
The 2700 Series has five filter slots to accommodate analog filters in nearly any configuration. Standard configurations already include the S-AES17 or OPT-2020 filter. See below for other filters, or contact your local AP sales partner if you have more custom needs. For more information about filters, visit the Option Filter page.
2700 Series standard configurations also include tone burst, square wave and noise generation (formerly option S2-BUR).
Analog options
• S-AES17: Special lowpass filter satisfies AES17 for measurements in the presence of out-of-band noise. Includes 20 kHz and 40 kHz brick wall filters (FLP-B20K and FLP-B40K). This filter requires two filter slots.
• OPT-2020: Pre-analyzer lowpass filter
• S2-IMD: Adds IMD generator and analyzer to SYS-2702, SYS-2712, or SYS-2722
• S2-W&F: Adds wow and flutter analyzer to SYS-2702, SYS-2712, or SYS-2722
• S2-BUR: Adds tone burst, square wave and noise generator to SYS-2702, SYS-2712, or SYS-2722 (now included standard with all 2700 Series)
• S2-EURZ: Changes analog generator source impedance to be 40, 200, or 600 ohms in SYS-2702, SYS-2712, or SYS-2722
• OPT-2711: Adds the Dolby Digital Generator option to a new SYS-2722, allowing the encoding of stimulus tones in Dolby Digital (AC-3) before digital output. Includes IEC61937 and licensed Dolby Digital encoding software, and proprietary Audio Precision streaming interface (APSI) hardware installed in the instrument. (Not compatible with GPIB systems, not compatible with 64-bit versions of Windows. See AP Software Windows Version Compatibility for details.)
Optional Analog Filters
Up to 5 optional hardware filters may be installed in the analog analyzer in SYS-2702, SYS-2712, or SYS-2722. Other designs may be feasible for special applications. Contact Audio Precision for quotations.
