Configuration

A Hoellstern DELTA 4-channel amplifier contains two identical amplifier modules. Module 1: C 1 / C 2 and module 2:
C 3 / C 4. Both modules are fed from a common power supply. A Hoellstern DELTA 2-channel amplifier contains one
amplifier module. Each amplifier module has two channels. Each amplifier module may be operated in bridge mode.
If on a 4-channel amplifier one module is operated in bridge mode and the other module in stereo mode, we have a
three-channel amplifier. If both amplifier modules are bridged, we have a two-channel amplifier.
Owing to special circuit technologies, Hoellstern amplifiers achieve almost double the output power at halved
impedance (load stable iCVP® technology). For this reason Hoellstern amplifiers can be used in a very flexible and
cost-efficient manner, and they sound excellent even at low impedance loads over the entire frequency range.
Via the terminal assignment of the SpeakON output sockets and the positions of the configuration switches on the
rear panel different operating modes can be configured. Each amplifier module has two Neutrik high-current
SpeakON sockets and a quad configuration switch. The contacts of the encapsulated toggle switches are gold-plated
for optimum contact safety and have a typical lifetime of 20,000 cycles.
Each amplifier module may be operated in one of the following modes:
Stereo: 2 channels with 2 independent inputs.
Mono: 2 channels mono parallel, with one input CH 1 or CH 3 resp. The other
input (CH 2 or CH 4 resp.) has no function.
Bridge: 1 channel in bridge mode, with one input CH 1 or CH 3 resp. The other
input (CH 2 or CH 4 resp.) has no function.
Exception: With models DELTA 14.4 and DELTA 14.4-DSP the CH3 / CH4 module has no Bridge /
Stereo configuration switch. The module always works in stereo mode. If you wish to work in
MONO mode, the channels must be slaved with short XLR cables.
