X-Amps
First of all, we would like to take the opportunity to thank you for and congratulate you on buying the
DYNACORD X-Amp Series power amplifiers.
X-Amps - a modular power amplifier concept and the most flexible solution for any mobile and permanent
installation application. The modular architecture of the X-Amps allows flexible selection of filter / signal
processor as well as input and output modules. This provides the possibility to easily include X-Amps
power amplifiers into basically any existing and most of all any future application, using principally any
connection technique. Factory-shipped, the X-Amps are equipped with an input module Xi-11 (XLR-type
inputs with thru-connectors) and an output module Xo-1 (SPEAKON-type connectors). The front slots of
the X-Amps are covered with blind panels. These slots are meant for including filter or signal processor
modules into the signal path. Next to generic modules for general use, cabinet-pertinent modules for
DYNACORD V-Systems loudspeakers are available, which in regard to their response and dynamic
capacity optimally match the equalization of the V-Systems loudspeaker components.
The use of front modules makes it easy to establish high quality and yet cost effective multi-way systems
while cabling of the entire system is drastically reduced.
The power amplifiers X1201 providing 1 x 1200W into 4 ohms and X1202 providing 2 x 600W into 4 ohms
unite outstanding audio performance, highest reliability, and security.
The gapless protection concept not only prevents the power amplifiers from being damaged but also the
connected loudspeaker systems. This extensive protection circuitry includes dynamic limiters, DC/HF
protection, Back-EMF protection, inrush current limiter, short circuit protection, thermal brain circuit, and
of course the protection against thermal overload of the power stage transistors and the transformers.
During “soft start”, delayed switching the power outputs is performed via relays.
Thermal stability is guaranteed through extremely low-noise, 3-stage fans.
The air circulation is front-to-rear, allowing trouble-free operation even in smaller power amplifier rack
systems.
The embodied comparators constantly monitor the power amp’s input and output signals, and control the
integrated limiters whenever non-linearity is detected, thus protecting the connected loudspeaker systems
against overload and power amplifier clipping. The overall response of the X-Amps is simply extraordinary.
Using widely dimensioned power supplies with low-loss toroidal transformers provide additional headroom
way above the stated nominal power output capacity. The power amplifiers do not employ V/I-Foldback-
Limiters, which allows to drive even complex loads with phase angles of up to 90° without a problem.
Also the mechanic construction and manufacturing guarantee highest precision. The robust and highly
rigid steel chassis is meant to survive the extensive wear of touring applications. The easily readable
LED-display provides quick information about the power amplifier’s operational state. Ready-mode, signal
presence, and the activation of limiters or of one of the protection functions are indicated for both channels
individually. All X-Amp Series power amplifiers are capable of handling loads down to 2 ohms.
This owner’s manual holds information about many other features of the X-Amp Series power amplifiers.
Therefore, carefully reading the entire manual is strongly recommended, so that you are able to get the
best performance from your new DYNACORD X-Amp Series power amplifier.
