SP Series User Manual
Welcome to Vibe Labs
Thank you for investing in the SP Series of professional power
amplifiers from Vibe Labs! Your trust is well placed in what we
believe to be one of the best specified, best designed and best
built digital power amplifiers available. We have spent countless hours poring over the
many details that make up a sophisticated product like the SP series to ensure that you
enjoy many years of flawless performance.
Please take the time to read through this User Manual in order to fully appreciate all of
the features and benefits of the SP series. Or, if you are experienced go ahead and read
over the Quick Start on page 4. Ultra-seasoned “road dogs” might be tempted to skip
even those instructions. If that’s the case then at least please check these two items so
that we don’t blow anything up:
1. Make sure the AC VOLTAGE SWITCH is set correctly for your region.
2. Do not connect a BRIDGED MONO load to the amplifier; it will fail immediately.
Now if you’d like to discover all of the other features such as the switchable noise gate,
auto-mute gain control and security lock functions or you’d like more information about
controlling and monitoring the amplifier from a computer, then you’d best read on. The
SP series has a lot to offer and we want you to get the very most out of it.
Finally, I’d like to encourage you to think about how you may be able to reduce your
carbon footprint in this age of environmental awareness. At Vibe Labs we’ve made a
commitment to become carbon neutral by reducing, re-using and recycling. While we
can’t do it alone we know that every little bit helps. You can do your part by turning off
devices (including this amplifier) when not in use. It’s only one small step but it will
make a difference.
Thanks again for putting your trust in Vibe Labs.
Sincerely
Costa Lakoumentas
Founder & CEO

SP series amplifiers are fitted with the
three most popular connector types for
signal input; XLR/TRS combination input
jacks as well as detachable Euroblock-
style connectors.
All connectors will accept balanced or
unbalanced signals from a variety of
high and low-impedance source devices.
For optimal performance and signal
integrity it is highly recommended that all
signal sources be balanced. Unbalanced
connections can introduce noise and
hum into the signal chain and should be
avoided.
Keep the connecting cables between the
amplifier and the source device as short
as possible to minimize the potential
for interference from other electrical
devices. Where possible run signal cables
away from sources of electro-magnetic
interference such as lighting dimmers,
refrigeration compressors, electric
motors, fans and other similar devices.
Balanced Signals
Balanced signals use cables with two
conductors plus a shield drain wire. One
conductor is labelled (+) and represents
the POSITIVE or HOT terminal. The second
conductor is labelled (-) and represents
the NEGATIVE or COLD terminal. The drain
wire is labelled (S) and represents the
SHIELD or GROUND terminal.
XLR connectors should be wired as per
AES14-1992, with Pin 2 Positive-polarity,
Pin 3 Negative-polarity and Pin 1 Shield.
Euroblock connectors provide a quick and
secure audio connection that does not
require soldering yet allows the connector
to be detached easily as needed.
Matching terminal plugs are provided for
each channel and are installed on the
amplifier. Terminate the wires as shown in
the diagram and as printed on the rear of
the amplifier.
Balanced TRS connectors are to be wired
with Tip Positive-polarity, Ring Negative-
polarity and Sleeve Shield.

SP Series User Manual
SP series amplifiers are designed to be
operated continuously in demanding
professional audio applications. To
ensure continued trouble-free operation
make sure that your amplifiers are
properly connected, powered and
protected and that there is sufficient
airflow around them. The following items
are considered good practice and should
be implemented in every installation.
Power
Ensure that each amplifier is connected to
a properly rated power outlet that is fused
for the anticipated load. Do not share
outlets with other devices or appliances
and ensure that the selected AC circuit
does not also feed other outlets or lights.
Where possible, locate the amplifiers
close to the breaker panel or transformer
or ensure that the feeder cables are
sufficiently rated to ensure a minimum of
voltage sag under load.
Grounding
Amplifiers should be properly grounded
to Earth through the building’s electrical
system. It is strongly advised that you
test the actual integrity of the grounding
system in the venue with a proper
electrical tester. Never operate the
amplifier without a proper ground, or
use a two-conductor AC input cable.
Performance will be degraded and a
severe risk of injury or death could be
posed by such operation.
Signal Cables
All input signal cables should be properly
shielded and balanced. While SP series
amplifiers will accept unbalanced signals,
noise performance and signal integrity
will be degraded, especially in areas
of high electro-magnetic fields or near
commercial or consumer transmitters,
computers or networking equipment.
Speaker Cables
Ensure that all speaker cables are sized
correctly for the speakers connected and
the powered being delivered to them.
A large portion of the electrical energy
delivered at the amplifier’s output can be
lost to heat in the speaker cabling, unless
it is sized correctly. Calculating the correct
size of the wire needed requires knowing
the load impedance, the amount of power
to be delivered and the total length of the
speaker run.
Cooling
SP series amplifiers are highly efficient,
converting most of the electrical power
they draw into power at the outputs, and
not heat. Most of the time they are cooled
passively and the internal fan does not
run, but under continued use at higher
power levels the fan will start to ensure
that the amplifier does not overheat.
The fan pulls air in from the rear of the
amplifier and expels air from the front.
12. OPERATION

Page 19
SP Series User Manual
It is critical that the front and rear air
vents are not obstructed and that the
amplifier is located in a space where there
is sufficient air volume and circulation to
ensure continued cooling.
Avoid installing the amplifiers in a closed
cabinet or a small room without access to
fresh air circulation. Amplifiers mounted
in a rack will require vent panels to be
installed, possibly with supplemental fans
to continually exchange the air inside the
rack. In larger installations supplemental
room cooling may be required to
maintain the ambient temperature within
operational limits.
