Rear Panel Connections
The PowerBloc5 has 3 types of connectors on the back panel,
one IEC male power receptacle, 10 RCA style connectors, 5 1/8”
City Lights
connectors and 5 pair of 5 way binding posts..
A. RCA
There are 2 RCA’s per channel. They are labeled “AC coupled”
and “DC coupled”. We recommend using the DC coupling to
prevent DC offset voltages from damaging the unit. However, if
you prefer to use the AC coupling and know that your
preamplifier is AC you may achieve a small improvement in
sound quality.
(If your unit is damaged due to DC offset
voltage you may be responsible for some or all of the
repair costs)
B. City Lights
The City Lights connectors provide power for lights only on
speakers featuring City Lights.These connectors provide 80 volts
@ .25 ma of current. If you choose to add light please make
certain that your devices will not draw more than this. (HINT:
most LEDs will work with appropriate resistor.)
C. Binding Posts
The 5 way binding posts allow easy connection of your
speakers. The preferred method of connection is using dual
banana plugs. These may be purchased through various
electronics retailers or directly from Legacy.
