1.Recessed Front Panel - Prevents switches and controls from accidentally being adjusted or broken.

2.Power Switch - Turns the amplifier ON and OFF

3.Power LEDs - Verifies that the amplifier channel is ON

4.Status LEDs - Displays the status of the amplifier. The LEDs are as follows: SIGNAL indicates if signal is present; CLIP illuminates if the amplifier is being overdriven; PROTECT illuminates if the amplifier is experiencing a “short” in the speaker array; THERMAL illuminates if the amplifier has shut down due an overheating condition.

5.Female XLR & 1/4" TRS Input Jacks - Feeds input signal to the amplifier using industry standard male XLR or 1/4" TRS (tip/ring/sleeve) plugs.

6.Male XLR Daisy Chain Jacks - Enables the connection of multiple amplifiers. The signal derived from the input signal is directly passed through (daisy chained) to these output jacks.

7.Stereo/Mono Switch - This dual purpose switch is used to select the operating mode of the amplifier. In Stereo mode the amplifier can be configured for standard 2-channel stereo operation. In Mono mode the amplifier can be con- figured for Standard Bridge mono, 70V mono or 100V mono operation. Turn amplifier off before operating this switch.

8.Level Controls - Adjusts the gain of the amplifier.

9.Load Switch - Selects the speaker impedance or transformer

voltage that will be connected the output binding posts. In Standard Mode the amplifier can drive 2, 4or 8speaker loads. In Constant Voltage Mode the amplifier can drive an array of speakers using 70V or 100V transformers.

10.Output Binding Posts - Connects the speaker array to the amplifier. These jacks allow bare wire, spade lugs or dual banana plugs to be connected to the amplifier.

11.Internal Fans - internal fans keep the amplifier circuitry cool. Allow a minimum of 3" clearance on the front and back of the amplifier vents for adequate ventilation.

12.Chassis/Float ground switch - Isolates Audio Ground and helps eliminate noise in the signal chain. With the switch in “Chassis” position, the audio ground is connected to chassis ground. In the “Float” position, the audio ground is isolated (floating) from the chassis. The chassis is per- manently connected to earth (safety) ground.

13.Mains Power Fuse - Protects the “mains” electrical cir- cuit in case abnormal current draw from the amplifier is experienced.

14.Mains Power Connector - Connects AC Voltage to the amplifier. The power connector is safety approved IEC type 320. The earth (safety) ground pin of the power connector is permanently connected to the chassis. This connection is capable of shunting in excess of 30A of fault current.

15.Biamp/Stereo Switch - This dual purpose switch selects either standard 2-channel stereo mode or 1-channel in, 2 channels out Biamp mode. Turn amplifier off before operating this switch.

16.Removable Rear Panel - 8 screws can be removed to ser- vice fans and internal components without unracking the amplifier.

SR2600, SR2300 specifications

The Hafler SR2300 and SR2600 are high-performance power amplifiers designed for audio enthusiasts seeking to elevate their listening experience. These models are renowned for their remarkable sound quality, powerful performance, and innovative technologies, making them ideal for both home audio systems and professional applications.

Starting with the Hafler SR2300, this amplifier is a two-channel powerhouse capable of delivering up to 150 watts per channel at 8 ohms, and 225 watts per channel at 4 ohms. One of the key features of the SR2300 is its Class AB design, which strikes an optimal balance between efficiency and sound fidelity. The design minimizes distortion, allowing for clear and precise audio reproduction across a wide frequency range. The amplifier also boasts a frequency response of 20 Hz to 20 kHz, ensuring that both low and high frequencies are accurately represented.

The SR2300 is equipped with a high-performance, toroidal power transformer, which enhances its ability to deliver a stable power supply to the output stages, resulting in improved dynamic range and transient response. Additionally, the SR2300 features comprehensive protection circuitry, safeguarding the amplifier from overheating and short circuits, ensuring reliable operation even under demanding conditions.

In contrast, the Hafler SR2600 offers even more power and versatility, pushing out up to 250 watts per channel at 8 ohms and 400 watts at 4 ohms. This model maintains the same renowned Class AB architecture as the SR2300 but integrates additional features such as a balanced XLR input for enhanced connectivity and reduced noise, which is invaluable in professional audio settings. The SR2600 also incorporates advanced thermal management systems, allowing it to operate efficiently even during prolonged use at higher output levels.

Both models come with customizable gain control options, allowing users to tailor the output to their specific needs. Whether being used to drive high-efficiency speakers in a home theater setup or powering professional studio monitors, the Hafler SR2300 and SR2600 deliver rich, detailed sound that remains consistent across various listening environments.

In summary, the Hafler SR2300 and SR2600 stand out in the audio amplifier market with their robust design, high power output, and advanced technologies that prioritize sound quality and reliability. These amplifiers continue to be favored choices for both audiophiles and professionals, ensuring an engaging and immersive audio experience.
