When working with a Lab.gruppen iP
Series amplifier, all necessary protection
is already built in to prevent damage to
your amp and as much as possible to
your speakers as well. All protection cir-
cuitry has an automatic reset, so you do
not need to worry, or take any action.
THERMAL PROTECTION
Should you – against all odds – manage
to overheat the amp, the Thermal
Protection will mute the affected amp
channel until it has cooled down.
ALS
®
Our smart ALS® is an ‘Adaptive
Limiting System’that monitors the out-
put signal continuously to limit its cur-
rent dynamically.
If for any reason distortion above 1 %
THD appears between input and output
of an amp channel, a Clip Limiter will
reduce the signal proportionally. You
only need to make sure that the input
signal is ‘clean’. The Clip Limiter is the
only protection that you can manually
defeat using recessed switches on the
rear.
VHF PROTECTION
To protect your HF drivers
from any oscillation, the VHF
Protection will mute the amp
once a signal above 12 kHz is
present at the amp’s output at
full output power for more
than five seconds.
AC MAINS VOLTAGE
PROTECTION
iP Series amps have an extrem-
ely wide window of operation
where mains voltage is con-
cerned; however, in the case of
the mains voltage being below
or above the window of opera-
tion, the amplifier will mute
itself thanks to its AC Mains
Voltage Protection.
Naturally, all Lab.gruppen
amps are DC and Short Circuit
protected.
Average life is risky
enough. Audio is safe with
Lab.gruppen.
High-frequency drivers are well protected
by the automatic VHF-protection.

Protect Yourself?
We do not make receivers or trans-
mitters. From the early days that we
were making Switch Mode amplifiers,
we always complied with any emission
and immunity requirements,
including today’s tough
European Electro-Magnetic
Compatibility directive
(EMC).
With Lab.gruppen iP
Series amplifiers you do not
need to fear any interference
with RF equipment. If you
hear strange voices please
check elsewhere.
You’re not alone. When it comes
to power amps, Lab.gruppen is on
your side.
