LOAD SWITCH

The Load Switch - located on the front panel - allows the amplifier power supply to be matched to the speaker load for more efficient, cooler running operation.This unique feature of the GX2300/2600 allows each channel to be configured for 2Ω, 4Ω, 8Ω, or 70V, 100V mono operation. (also 70V Dual Mono-GX2600 only).

The power output and thermal performance of the amplifier remains consistent with all the possible combinations of the loads listed. In Stereo or Biamp mode the Load switches can be configured independently, and each channel will deliver the same consistent output power and thermal performance, regardless of how the other channel is configured. Use the fol- lowing guide when selecting the Load Switch setting:

Nominal Speaker Impedance

Load Switch Setting

5Ω-8Ωor higher

8Ω

3Ω-5Ω

4Ω

2Ω-3Ωor lower

2Ω

If the “Protect” LED is illuminated for prolonged periods during normal operation, select the next lower value Load Switch setting. Continue until the “Protect” LED ceases to illuminate, or lights infrequently. This switch can be safely operated while the amplifier is running. In 70V or 100V mode, the “Protect” LED indicates there are too many speakers loading the array.

THERMAL

Indicates when the thermal protection has shut down the amplifier. After cooling sufficiently, the amplifier will automatical- ly recover and continue operating.

CLIPPING

Lights up when the output or input signal reaches the maximum allowable voltage, and “clips” the output signal. Input clip- ping occurs at 3 VRMs (sine), and can be eliminated by attenuating the signal at the source unit - before it reaches the amplifier. Output clipping can be eliminated by turning down the amplifier level control.

To determine whether the signal is clipping at the input or output of the amplifier, perform this test: Turn the amplifier con- trol all the way “OFF”. If the clipping continues, this is an indication that the signal is clipping at the amplifier input.

SIGNAL

Monitors the amplifier output and indicates when a signal of at least 1 Vrms is present. A number of situations could exist where the input cable is properly connected to the signal source, but the Signal LED does not illuminate, such as:

Level control is not high enough to amplify the output signal to 1 Vrms.

Source signal is off, or lower than normal.

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.
