Introduction

The Hafler GX2300 and GX2600 amplifiers are two rack height, two channel, fan-cooled professional power amplifiers suitable for use in the most demanding sound reinforcement and commercial sound installations. These amplifiers offer out- standing efficiency by means of three technologies: high-efficiency Class-G Tri•nova amplifiers, high-frequency switching power supplies, and constant power output/load impedance selection switches. Crossover, Time Delay, Phase and CD Equalization features make the GX2300/2600 especially useful in 2-way cinema applications.

Technical Design Features

WHY A NEW AMPLIFIER TOPOLOGY?

Hafler TRANS•nova amplifiers, the recording studio reference, have a floating +/- power supply for each channel and a Nodal drive system covered by U.S. Patents 4,467,288 and 5,567,000. Our challenge was to convert this topology into a high efficiency design with minimal increase in complexity-yielding an amplifier of outstanding audio qualities, high effi- ciency and unprecedented value. Tri*•nova is the answer.

The most common high-efficiency (Class-H) methods raise the rail voltages going to the output devices for higher power levels. Tri•nova does not do this. Instead, it operates by forming a triplet or triplex of tracking signals: A, (A+V) and (A–V), where A is the raw audio output and +/– are the floating rails. The amplifier final output is selected to be at an appropriate voltage between (A+V) and (A–V) for each condition of the signal. The output voltage and current capability are each potentially doubled and the power potentially quadrupled–without having to increase the rail voltages fed to the devices. One or more patents are expected from this technology.

GX2600CE, GX2300, GX2600, GX2300CE specifications

The Hafler GX series amplifiers, including the GX2300CE, GX2600, GX2300, and GX2600CE, represent a sophisticated blend of power and precision in audio amplification technology. Designed for both professional and home audio use, these amplifiers deliver high-quality sound reproduction while maintaining reliability and durability.

The GX2300CE and GX2600 are particularly noted for their robust power output. The GX2300CE can produce an impressive output of 125 watts per channel into 8 ohms, making it suitable for driving a wide range of speakers with ease. The GX2600 pushes this power even further, targeting serious audiophiles who demand more dynamics and headroom from their audio systems. With a 220 watts per channel output at 8 ohms, it is built to handle even the most demanding acoustic environments.

One of the standout features of these amplifiers is their use of Hafler's proprietary "Current Feedback" technology. This innovative design allows for greater bandwidth and reduced distortion, ensuring that the audio signal remains true to the original source. The result is a clear, transparent sound that enhances the listening experience. Alongside this technology, the amplifiers come equipped with multiple input options, including XLR and RCA inputs, providing flexibility for various audio sources.

In terms of build quality, the GX series showcases Hafler’s commitment to durability and aesthetics. The rugged chassis is designed not only to withstand the rigors of both studio and stage environments but also to minimize resonance and external vibrations. The front panel is user-friendly, with easily accessible controls for volume and input selection, enhancing convenience in any audio setup.

The GX2300 and GX2600 also feature advanced thermal protection circuitry, preventing overheating and ensuring long-term reliability. This feature is particularly beneficial for extended playback sessions or in high-demand situations when the amplifiers are pushed to their limits.

In conclusion, the Hafler GX2300CE, GX2600, GX2300, and GX2600CE amplifiers are engineered to provide exceptional audio clarity, robust power, and advanced technology. Whether used in a professional studio or a home theater system, these amplifiers stand out for their performance and adaptability, making them a favored choice among audio enthusiasts and professionals alike.
