Xa2600 / PM 2600
The heart of any Xa-system, PowerMax system or of a
freely configured 2-way system is one of our 2600 Series
Controller Amps.
Based on the topology of the “LINEAR PRECISION” Series
power amps, these system power amplifiers offer an output power capacity of 2,600 watts (RMS) each, when
operated in active 2-way mode. Both models provide integrated active frequency crossovers, several processorcontrolled functions and extensive protection circuitry.
The provided output power is:
2 x 700 watts Lo
2 x 600 watts Hi
The multitude of processor functions includes our patented
LPN-filters, the ”Thermal Brain Circuit" protection, and an
APC-controlled limiter for each amplifier channel.
Additional protection circuitry prevents thermal overload,
HF, DC or short-circuit in the output stage. The Linear
Precision Series' Back-EMF-protection circuitry contributes
to the overall operational stability.

Originally designed for the Xa-Systems, this system power
amplifier offers various adjustment features and reveals its
true versatility when being used with any other Hi/Mid/
Sub woofer speaker system combination.
The Mid/Hi-Equalizer with integrated horn-equalization at
12 kHz can be optimally used with medium or long-throw
Mid/Hi speaker systems.
Separating the LF-range from the rest of the audio signal,
an active Butterworth/Constant-Power-Response-Crossover provides a crossover frequency at 160 Hz with
18 dB/oct. slope. A 12 dB/oct. Lo-Cut filter cuts ultra-low
frequencies below 30 Hz.

The integrated bass equalizer is meant to be used for live
concerts. The 4 kHz Dip-switched EQ allows the adjustment of several different cabinets to match varying acoustical environments. A 12 dB/oct. Lo-Cut filter attenuates
ultra-low frequencies.
• LPN Processor Function
The patented LPN-Processors (Low Pass Notch Filter)
electronically neutralize speaker-typical transient response
distortion already within the power amp.
• APC Processor Function
Four super-high-speed audio processors continuously
monitor the amplifier's internal and external operational
state, activating the four internal dynamic limiters on the
occurrence of any non-linear operation.
• TBC Processor Function
Four Thermal-Brain circuits simulate the thermal model of
a typical voice coil and limit the energy fed to the speaker
components during impending overload.

Dual Active 2-Way
”PowerMax“ Controlled Amplifier

Basically, the PM2600 can drive any active 2-way system
that consists of full-range cabinets and sub woofers. The
integrated frequency crossover operates in PowerMax
function mode and has been optimised for those combinations. Intelligently configuring system components
leads to outstanding results. For more details, please refer
to the PowerMax Systems and PowerMax230 Controller
descriptions.
