Connecting the EC4½ :
Connecting to mains
Check that the mains voltage printed on the rear panel of the preamplifier corresponds
with the line voltage in the territory were you intend to use your preamplifier.
How to avoid damages
A good operating practice is to turn off all equipment before any connections or
disconnection’s are made. Do not under any circumstances connect or disconnect
equipment when power is turned on. If you insist on connecting or disconnecting while
power is turned on, you should be aware that the design of the RCA plug generates a
large transient when inserting the plug. This could damage both the speakers and the
power amplifier.
The rear panel
The rear panel of the Preampliwire EC 4 1/2 contains all input and output connectors.
The printed rear panel clearly indicates the function of each connector.
Single RCA input operation
The single end RCA inputs will work with any line level source. Simply connect the RCA
plugs from the source to the RCA socket. Switch the input selector on the frontpanel of
EC 4 1/2 to single mode.
Balanced XLR input operation
The balanced mode can only be used if the source has a balanced output. In order to
use the balanced XLR input, connect the XLR plugs from the source to the XLR
socket. Switch the input selector on the frontpanel of EC 4 1/2 to balanced mode.
