We recommend that the Relay Switcher is placed close to the amplifiers, and the Selector unit close
to your listening position. They should be linked with a good quality network cable (CAT5 or CAT6).
We have tested up to 20m.
For plugging in the guitar there are two possibilities (included with the
HeadLine
is a 5m guitar
cable):
Guitar is plugged into the front of the Selector unit, which is paralleled to two connectors on
the rear, one for connecting to a tuner and one to route to the Relay Switcher; this cable can
be plugged into the front or rear of the Relay Switcher
Guitar is plugged into the front of the Relay Switcher unit and the jack on the rear can be
connected to a tuner
On the rear of the Relay Switcher unit are a number of jack sockets, an RJ45 input and the mains
power connector.
The left most socket (GUITAR IN/TUNER) will either be fed as
Option 1 from the guitar selector unit
,
or as
Option 2 to a tuner
(see connection diagram).
The eight TO AMP sockets should be connected to the inputs of amplifiers 1 -8 with high quality
guitar cables.
The CONTROL IN socket requires a standard CAT5/6 network cable connected to the selector unit (a
5m cable is included with the
HeadLine
).
The eight FROM AMP sockets come from the amplifier loudspeaker outputs. We recommend
loudspeaker cable, 1.5mm2/conductor (AWG 15/16), with high quality jack plugs (gold plated for
long term reliability).

The four TO SPEAKER sockets are connected to the loudspeakers. Again, we recommend
loudspeaker cable, 1.5mm2/conductor (AWG 15/16), with high quality jack plugs (gold plated for
long term reliability).

To enable us to house it all in a 1U case, we used Neutrik stacking jacks. These have a 16.5mm (.65”) vertical
gap between sockets so will not accept ‘jumbo’ jacks. Neutrik NP series jacks have a diameter of 14.5mm
(.571”), and the NPC series 16.2mm (.638”) and both will fit. Both accept cables of diameter 4-7mm (.157” -
.279”) and the NP series have an optional bush that will accept cables from 7-8mm (.276” - .315”)
