Thank you for purchasing the NOBELS SPLIT-MASTER!
The SPLIT-MASTER is a universal high-quality signal splitter for music applications and
distributes incoming audio signals to several outputs. The device can distribute up to four mono
(or two stereo) inputs to up to four outputs each, simultaniously and without loss in signal quality.
The buffer outputs convert high impedance instrument signals to low impedance signals that
are much less susceptable to electrical interference when using long cable runs.
Correct setup and operation of the SPLIT-MASTER are very easy and there is almost no
possibility of maloperation. However, please read this manual thoroughly prior to use anyway
in order to fully understand the working principle of the SPLIT-MASTER and prevent any possible
confusion.
Connections:
If all four inputs are occupied the respective signals are automatically distributed to two outputs
each:
In order to achieve a distribution to four outputs each only inputs 1 and 3 may be employed. In
this case input 1 is internally routed to input 2, thus distributing the signal to both "direct"
outputs 1 and 2 as well as the respective "buffer" outputs.
The same holds true for input 3, whereas the input signal is then distributed to output pairs 3
and 4 in parallel:
Power switch:
Switches the device
"on" or "off".
When switched off the inputs remain
connected to the direct outputs.
Power indicator:
The LED lights when
a proper operating voltage is supplied
and shows that the A/B-MASTER is
switched on.
DC in jack:
The connection for a regu-
lated DC power adaptor to supply a
proper operating voltage to the A/B-
MASTER.
Please refer to the technical data sec-
tion for details.
DC out jack:
Further devices (e.g. ef-
fect pedals) can be connected here for
feeding them off the A/B-MASTER´s
power supply.
Direct outputs 1-4:
The upper four
jacks carry the direct signal of the re-
spective input jack.
Buffer outputs 1-4:
The input signal is
also tapped and routed to its respecti-
ve "buffer out" via an electronic buffer
stage.
This effectively prevents a possible
loss in level and/ot signal quality from
interference between the outputs.
This requires the external power adap-
tor to match all necessary specifica-
tions and to be able to supply an ade-
quate current.
Regarding polarity, plug size etc. NO-
BELS follows the standard of the
world´s most popular effects lines so
there should be no problems to be
expected in most cases.
Input jacks 1-4:
The signal sources
e.g. outputs of musical instruments to
be distributed are connected here.
Please refer to the "connections" sec-
tion of this manual for details.
All signal connections are made using
regular instrument cables with mono
jack connectors.
In addition the buffer provides a strong
low impedance output signal that can
be carried over long cable runs safely.
