Adds 8 unamplified stereo zone outputs to a Sonnex® Multiroom Audio System.

The SWE-8 is an 8-zone unamplified expander for the Sonnex® Multiroom Audio System (SWAMP-24X8[1]) from Crestron®. It provides 8 zone outputs consisting of 4 analog line-level and 4 SPDIF digital outputs. All eight outputs also include Crestron Home® (CH) CAT5 balanced audio outputs for long-distance wiring applications. The SWE-8 is ideal for routing audio to AV receivers, powered subwoofers, headphone amplifiers, phone systems (for music-on-hold), and other audio equipment.

8 Zones Unamplified

  • The SWE-8 allows routing of any of the main SWAMP-24X8's 24 source inputs to any of its eight zone outputs. Outputs 1-4 offer balanced, unbalanced, and CH outputs. Outputs 5-8 offer SPDIF and CH outputs.

Crestron Home® CAT5 Audio Distribution

  • The CH CAT5 balanced outputs enable long-distance wire runs up to 500 feet (152 meters) to feed remote equipment such as powered subwoofers and AV receivers located throughout the house. The CH signal is easily converted to unbalanced line-level at each remote location using an ABAR-1 CAT5 Balanced Audio Receiver[1]. CH outputs are also compatible with other Crestron Home products such as the C2N-IADS30X24, CNX-BIPAD8, CNXRMCLV, C2N-DAP8, and certain Crestron touch screens.

AUD-EXT Audio over CAT5 Extenders

  • For long-distance wiring applications requiring wire runs over 500 feet, Crestron offers the AUD-EXT family of audio extenders[1]. Using inexpensive CAT5 wire, these extenders allow unbalanced audio signals to be extended up to 2000 feet (610 m), while SPDIF signal can be extended up to 600 feet (183 m).

Digital Signal Processing

  • Each zone features independent DSP for optimal sound quality and control in every room. Sonnex DSP capabilities include the choice of graphic or parametric 5-band EQ, dynamic range control, volume, bass, treble, balance, loudness, mute, mono summing, and five selectable tone profiles. For subwoofer applications, a choice of 2nd or 4th order active crossover filters can be set using the parametric EQ, leaving the four remaining EQ filters available for room correction and tonal enhancement.

Output Bussing

  • Output bussing allows multiple zones to function as one, whether fed from the SWE-8, the SWAMP-24X8, or another Sonnex Expander. Output bussing is ideal for grouping adjacent listening areas together or associating a powered subwoofer with its stereo speaker pair. Volume Offset adjustments allow for balancing the levels of each bussed zone for smooth, even coverage.

Simple, Versatile Installation

  • The SWE-8 can be installed along with the SWAMP-24X8 at the central equipment rack, or separately at a remote location. It interfaces with the SWAMP-24X8 via a single CAT5e shielded twisted pair (STP) cable up to 200 ft (61 m) in length[2]. This length can be increased to 2000 ft (610 m) using multimode fiber optic cable with the S-EXT1-S Sonnex Link over Fiber Extender[1]. Plug-and-play connectivity affords an extremely easy installation with full control access to all the SWE-8 functions provided through the SWAMP-24X8.
  • Please see the SWAMP-24X8 spec sheet for complete Sonnex system information.
