Dynacord Xa2600, PM2600 User Manual

POWER AMPLIFIERS

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.

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 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.

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.

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.
