To Connect to the Power Amplifier:
1. Your existing speaker wires can be twisted together with the signal
interconnect to STUDIO and connected to the gold plated 4mm plugs
supplied. Alternatively, use your existing plugs or connect the STUDIO lead
to a spare set of speaker terminals. In effect the STUDIO is bi-wired from
your power amplifier. However, note that there are only three connections to
STUDIO. This is deliberate and helps preserve the existing star earthing of
your system (assuming it has a star earth arrangement). Remove the
speaker leads to the RIGHT or the LEFT channel of your power amplifier
(whichever is the most convenient). Connect either one of the RED banded
plugs on the interconnect to the RED terminal of whichever channel you have
selected on your power amplifier. Connect the BLACK banded plug from
STUDIO to the BLACK terminal of this channel. Now do the same with the
other channel by connecting the other RED banded plug to this channel’s
RED terminal. Connect the XLR plug to the high level input on STUDIO.
3. Connect the Mains lead to STUDIO and to the mains and switch ON.
Operate the Earth Lift switch, if there is no hum, leave in the OUT position.
This ensures that there is only one earth return on your system, preserving
the star earthing arrangements in your power amp. If the XLR plug is
removed there will be a hum. The hum can be removed by operating the
earth lift switch if desired. Sometimes this hum will reappear if the main
power amp is switched off. If this occurs, leave the earth lift switch IN.
To Connect to a Dedicated Sub-woofer Output:
1. For this connection it will be necessary to use whatever type of connector is
needed by this output. Normally it would be a phono type connector.
Whatever the type, the yellow wire of the STUDIO interconnect should be
connected to the signal live of this connector and the red and black to signal
ground. The red wire is connected to ground to minimise hum pickup. The
600 Ohm balanced line input is then used in place of the high level XLR
input. With very long interconnects and some amplifiers, particularly ones
with a higher output impedance, there may be a slight hum. If so, screened
interconnect will have to be used.
2. Plug the connector into the dedicated sub-woofer output on your power
amplifier and the XLR plug into the 600 Ohm balanced Line level input on
STUDIO.
3. Follow Step 3 above to connect to the mains.
