AP - The Recognized Standard In Audio Test

2700 Series Hardware OptionsHOME/PRODUCTS/2700 SERIES/HARDWARE OPTIONS

AP 2722

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.
