ZXSUM8
CONFIGURATION
Internal Mode Switches: Change the mode of channels 2–4 between summing plus line-output conversion
(LOC) and line-output-conversion-only by fl ipping the internal switches, accessible by removing the cover of the
ZXSUM8.
Use LOC-ONLY mode to convert a channel’s input from high-level (speaker-level) to a low-level signal suitable for
connection to an amplifi er.
Use SUM+LOC mode to mix the channel in question with Channel 1. The mixed signal appears on the Channel
1 output at low-level suitable for connection to an amplifi er. The channel’s original signal is also converted to low-
level then passed through to its corresponding output.
