SPECIFICATION

The power amplifier shall be capable of stereo, mono bridged or parallel (daisy chain) operation. In stereo mode, it shall deliver a minimum of 750 watts into loads of 4 ohms each with both channels operating. In mono bridge mode, it shall deliver a minimum of 1500 watts into an 8 ohm load. It shall be cooled by two temperature sensitive speed-con- trolled fans, and shall have internal short-circuit and thermal protection circuitry. A protection LED indicator shall acti- vate and the power amplifier shall shut down to protect against short circuits, overheating, severe overcurrent con- ditions or DC offset present at the outputs. The power amplifier shall have slow start-up and muted inputs on turn- on. Inputs shall be on XLR and locking balanced 1/4tip- ring-sleeve connectors. Outputs shall be on Banana jack and Speakon™ connectors. The front panel shall have indepen- dent level controls for left and right channels, a master power switch and LED indicators for power, clip, -20dB, -40dB and amplifier protection.

The power amplifier shall have a frequency response of 9 Hz to 42 kHz, signal-to-noise equal to or greater than 105 dB and THD less than 0.03%. The dimensions shall allow for standard 19EIA rack mounting. It shall be 5.25(133.35 mm; 3 rack spaces) high and 9.75(247 mm) deep. Weight shall be 48 lb. (21.8 kg). The power amplifier shall carry a three-year warranty.

The power amplifier shall be a SAMSON S1500.

S1500 specifications

The Samson S2000 and S1500 are renowned headphone amplifiers that have gained popularity among audio enthusiasts for their superior performance and technological innovations. Both models embody Samson's commitment to high-quality, reliable audio solutions suitable for both professional and home studio environments.

The Samson S2000 is designed to provide high-quality sound amplification for professional-grade headphones. It offers an impressive output power of 2000mW per channel, ensuring that even high-impedance headphones can achieve full performance. One of its standout features is the incorporation of a low-noise, high-performance amplifier, which delivers clean, distortion-free sound across a broad frequency range. The S2000 includes a front-panel volume control that provides precise adjustment, making it easy for users to find the right listening level in any environment. Additionally, it features two headphone outputs, allowing multiple listeners to enjoy audio simultaneously, which is particularly useful in collaborative settings.

On the other hand, the Samson S1500 incorporates similar high-quality engineering but is designed with slightly more compact dimensions and output specifications. The S1500 provides 1500mW per channel, showcasing ample power for a variety of headphone types. This model also includes a front panel volume pot and a headphone output switch to select between two headphone outputs. A significant feature of the S1500 is its low-frequency extension, providing richer bass response ideal for those who appreciate depth in their audio experience. The S1500 incorporates advanced thermal management technology to ensure stable operation and prevent overheating, a crucial consideration for long listening sessions.

Both the S2000 and S1500 are equipped with ¼-inch and 1/8-inch inputs, making them adaptable to a wide range of audio sources. They utilize a robust, solid metal chassis designed for durability and reduced vibration, enhancing overall audio fidelity and ensuring longevity. Additionally, both models feature a sleek design, making them visually appealing in any setup.

In summary, the Samson S2000 and S1500 headphone amplifiers exemplify top-notch design, functionality, and power optimization for audio professionals and enthusiasts alike. Their combination of innovative technologies, robust output capabilities, and user-friendly features make them exceptional choices for anyone looking to enhance their listening experience.
