WIRING THE SPA-8
Connecting to the mains outlet
Connect the SPA-8 with the supplied mains power cable. It is constructed of large enough wire gauge and an
appropriate plug. Do not substitute with another power cable.
Connecting balanced sources
To fully realize the sonic potential of your SPA-8 Stereo Power Amplifier, use balanced connections at its
input. Balanced cables minimize interferences from magnetic and RF sources. Connect your preamplifier
output to the input provided on the rear panel of the SPA-8. The SPA-8 conforms to the standard of pin2 as
“hot” i.e. a positive voltage at pin2 will produce a positive voltage at the “+” speaker terminal.
Connecting unbalanced sources
If you should need to connect unbalanced equipment, use the following special cable wiring to get the best
performance.
Connecting your loudspeakers
Two sets of output terminals are provided for easy bi-wiring. Do not use tools on the speaker terminals but
rather tighten them by hand only.
! This is a high-power amplifier, when driven there is
high voltage at the speaker terminals! Connections
should be only made with the mains disconnected!
