The SWE-8 is an 8-zone unamplified expander for the Sonnex® Multiroom Audio System (SWAMP‑24X8, sold separately). It provides 8 zone outputs consisting of 4 analog line-level and 4 S/PDIF digital outputs. All of the outputs include 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 routes any of the SWAMP-24X8' s 24 source inputs to any of its eight zone outputs. Outputs 1 through 4 provide balanced, unbalanced, and CH CAT5 outputs. Outputs 5 through 8 provide S/PDIF and CH CAT5 outputs.

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 (sold separately). Using inexpensive CAT5 wire, these extenders allow unbalanced audio signals from the SWE‑8 to be extended up to 2000 f t (610 m), while S/PDIF signals from the SWE‑8 can be extended up to 600 f t (183 m).

Digital Signal Processing
Each zone features independent digital signal processing (DSP) for optimal sound quality and control in every room. 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 second- or fourth- 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 the levels of each bussed zone to be balanced 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.¹ This length can be increased to 2000 ft (610 m) using multimode fiber optic cable and the S-EXT1-S Sonnex Link over Fiber Extender (sold separately). Plug-and-play connectivity affords an extremely easy installation with full control access to all the SWE-8 functions provided through the SWAMP-24X8.
