The XDA-QS5400RK is a stereo power amplifier from Yamaha, built with an exceptional signal-to-noise figure in a remarkably slim rack-mountable chassis. The XDA-QS5400RK brings Yamaha's considered engineering to a space-efficient power amplification format.
Key specs that matter
Input sensitivity is 150mV. Output power is 50W into 8 ohms, rising to 100W into 4 ohms. Gain is 25.8dBu. Frequency response spans 10Hz to 22,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is an exceptional 114dB, with total harmonic distortion plus noise at 0.04% at 100% global feedback. At a remarkably slim 437 x 46 x 443mm and 6.3kg, the XDA-QS5400RK maintains a space-efficient, rack-mountable power amplifier chassis.
Sound and use context
Expect exceptionally clean amplification reflecting the exceptional 114dB signal-to-noise figure, packed into this remarkably slim, rack-mountable chassis suited to custom-installation or space-constrained applications.
Pairing
The remarkably slim, rack-mountable chassis suits custom-installation applications where equipment rooms and rack space are a design consideration.
Alternatives
Other manufacturers' rack-mountable power amplifiers offer alternatives for buyers wanting to compare this space-efficient category.
