Philips - Sound Enhancer IS 5021 Signal processor

Philips Sound Enhancer IS 5021
Exclusively on CATAWIKI
Brand new in its original packaging.

This product offers recording studio engineers, home studio owners, post-production facilities, enterprise audiovisual centers, archivists, and broadcast professionals unparalleled value for an integrated set of advanced sound processing technologies developed by Philips.

The IS5021 standard includes the following elements:
• - 20-bit A/D converters (ADMOD79)
• - High-quality D/A converter (based on the Philips DAC7)
• - Sampling rate converter for the interface between equipment operating at different sampling frequencies

Digital sound processing, including:
• - Vibration suppression (for cleaning DAT recordings)
• - Compression/Expansion
• - Noise reduction (including a low-pass filter with adjustable cut-off frequency)
• - QNI (quantization noise imaging)
• - Slave mode (for external synchronization)
• - Varispeed (pitch variation can be processed without affecting the output sampling frequencies)
• - Scratch suppression (de-click)
• - Stereo enhancement (stereo effect from mono)
• - Spatial stereo (expand or narrow the sound stage)
• - Bass, treble, balance, and volume adjustments
• - Digital level indication and control (for monitoring overall input level)

These features give professional sound engineers great versatility for creating digital recordings from analog or digital sources. The IS5021 is particularly suited to the following applications:

Recording/Production studios:
The 20-bit A/D converter, paired with the sampling rate converter, allows selecting a 44.1 or 48 kHz sampling rate for digitizing old DAT recordings. In fact, any input sampling frequency between 15 and 50 kHz is accepted.

Broadcasting professionals/Archivists/Home studios:
The IS5021 offers a broad range of intuitive tools to improve the sound of older recordings (tapes and vinyl). Among these tools is stereo enhancement, which allows converting a mono recording to stereo (phase-decorrelation), stereo spatial processing, which widens or narrows the sound image, as well as noise reduction and scratch suppression filters.

These features, combined with the digital-to-analog converter and the QNI interface, enable recording professionals to achieve higher-quality digital recordings and transfer them onto analog cassette for markedly improved quality, especially for portable listening.

Audio post-production:
field recordings with most common portable DAT recorders can now be edited to offer higher resolution and richer sound, with significantly reduced jitter distortion.
