HPA-A550 Fully Balanced Headphone Amplifier 2x25VA Transformer for TALEMA Preamplifier with Remote Control 115V/230V

Description:
- The sound characteristics of DHA-A550 is very neutral and transparent, high accuracy, low distortion, and very dark background; The precise and rational voice is pure and meticulous, without adding color grading or emphasizing any part of the expression, with the spirit of restoring the neutrality of the original sound; The neutral tone and comprehensive quality make it highly adaptable to headphones. It is not only an ideal choice for driving various flagship dynamic earphones, but also a high-performance front-end product, which has four major characteristics: low noise, high voltage, high output, and high damping coefficient.
- It can be used as a desktop computer, plugged in headphones for listening, or as an analog front-end output to desktop active speakers. Its quality and strength are sufficient for any purpose; The A550 not only has strong performance in ear amplification, but as a front-end, it can also achieve excellent results. The headphone output and line output can be enabled/disabled through buttons on the panel or remote control. In addition, there is a front-end volume direct/adjustable switch button.

Features:
- Low noise: very small internal gain, the amplifier's own background noise is basically inaudible.
- High output voltage: designed with a working voltage of ±25V, providing the most suitable sound for high impedance headphones. Therefore, it is very suitable for high impedance headphones that require high output voltage swing.
- High output power: thanks to powerful amplifiers, even the most demanding headphones require greater power. Therefore, it is most suitable for low impedance headphones and static magnetic headphones.
- High damping coefficient: a very low impedance that can ideally match difficult to drive headphones, resulting in uncompromising frequency characteristics.
- 3 analog stereo inputs: two RCA unbalanced, one XLR balanced.
- 3 gold-plated headphone output sockets: one 6.3mm unbalanced socket; one 4-pin XLR balanced socket; one 4.4mm balanced socket.
- 2 sets of line outputs: one set of RCA single ended and one set of XLR balanced line outputs.
- Earphone output and line output can be switched separately.
- Two 25VA sealed transformers for TALEMA, and audio capacitors for Nichicon with a total capacity exceeding 35000μF.
- Full relay input and output control.
- Independent design of left and right channels; The signal path adopts high-quality operational amplifiers and high-quality MKP capacitors.
- 256 levels relay resistance matrix volume, precise step control at 0.4db/level.
- Left and right channel balance adjustment function.
- 4-channel balanced amplification; 6.4W output power at 50Ω; Output voltage of 21.1VRMS at 600Ω.
- Multiple input and output gains adjustable; ±18db 5-speed adjustable gain, headphone/front-end gain can be adjusted separately, achieving perfect matching between audio source and headphones to achieve optimal input and driving effects.
- Comprehensive protection circuit, monitoring the DC voltage and overload output of the headphones.
- All metal remote control for volume, mute, input selection, and output selection.
