Dynacord Xa2600 - Manual

P O W E R A M P L I F I E R S 31
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-Cross-
over 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.
Xa2600 / PM 2600
Dual Active 2-Way
Processed Precision Power Amplifier
2600 Watts
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 out-
put power capacity of 2,600 watts (RMS) each, when
operated in active 2-way mode. Both models provide in-
tegrated active frequency crossovers, several processor-
controlled 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.
The integrated bass equalizer is meant to be used for live
concerts. The 4 kHz Dip-switched EQ allows the adjust-
ment of several different cabinets to match varying acous-
tical 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.
