Every FP+ Series amplifier is designed,
engineered, assembled, and rigorously tested
at Lab.gruppen's manufacturing facility in
Kungsbacka, Sweden. The uncompromising
dedication to quality and craftsmanship is
evident in every detail.

A full suite of protection features
Lab.gruppen's FP+ Series incorporates
comprehensive warning and protection
features to safeguard the amplifier
and all connected loudspeaker
drivers. Front-panel indicators and the
DeviceControl GUI give clear warnings
when any potential problems are

enabled only when critical thresholds
are passed: measurements are

signal. In addition, each channel
incorporates Lab.gruppen's exclusive
Voltage Peak Limiter (VPL) circuit. VPL
precisely tailors output for any type
of load, from a single massive 2-ohm
subwoofer to a series of 16-ohm mid-
or high-frequency drivers. Working in
concert, adjustable input gain and VPL
optimize each channel for maximum
headroom regardless of input signal
dynamics or load impedances.
Intercooler ® for efficient, uniform
cooling
Compact and ultra-efficient, Intercooler ®
uses thousands of tiny cooper
cooling fins to increase exposure of
the heat sink to the cooling air flow.
Twin variable-speed fans respond to
temperature sensors, forcing air over
the Intercooler ® fins in a front-to-rear
flow. All output devices are mounted
transverse to the airflow, so the cooling
effect is uniform. There are no "end of
tunnel" output transistors subject to
greater warming and, consequently,
possible premature failure.
