The ZXSUM8 is a unique interface with the ability to sum (or mix) multiple high-level/speaker-level signals together
to a single, low-level RCA output. The ZXSUM8 greatly simplifi es upgrading or adding an amplifi er (or amplifi ers)
to your factory source unit. Channels 1–4 can be independently switched internally to function as stereo line
output converters (LOCs) instead of the summing function.
Features
• 4 stereo speaker-level inputs
• 4 line-level stereo RCA outputs
• 1 stereo RCA aux-input
• Balance levels from multiple speaker-level sources
• Sums up to four speaker-level stereo pairs down to a single stereo RCA low-level output
• Each stereo channel is capable of both summing and line-output conversion; switched internally
• Integrates portable media direct to your amp using aux-in and level control
