DOUK AUDIO D5 Audio Selector Switch 1x RCA + 3.5mm Jack / 3x RCA + 3.5mm Jack with 5-Band Equalizer

The Douk Audio D5 is a multifunction audio selector switch combining source selector, audio distributor, 5-band stereo equalizer, headphone amplifier, and analog VU meter in a compact and robust format. Designed to simplify the management of multiple audio devices, it can operate either in 4-IN-1-OUT mode to select one of four connected audio sources, or in 1-IN-4-OUT mode to distribute a signal simultaneously to multiple amplifiers, active speakers, or audio systems. Compatible with desktop and home HiFi setups, it features one side with RCA + 3.5mm jack connectivity (priority input) and another side with three RCA + 3.5mm jack connections.

The D5 also integrates a 5-band analog equalizer allowing precise frequency adjustment at 80Hz, 330Hz, 1kHz, 3.3kHz, and 10kHz with a ±10dB adjustment range, as well as an EQ Bypass mode allowing the correction circuits to be completely bypassed in order to preserve a pure and unmodified audio signal. Its integrated headphone stage can drive headphones with an impedance between 32Ω and 200Ω, with an output power of 150mW at 32Ω, providing detailed and dynamic personal listening.

The D5 also stands out thanks to its large backlit analog VU meter, whose brightness can be adjusted across 6 levels, with adjustable needle movement amplitude to adapt the display according to the signal level. Thanks to its 50KΩ input impedance, 10Ω output impedance, and frequency response from 20Hz to 20kHz, it ensures excellent compatibility with the majority of audio equipment. Powered by DC 5V / ≥2A, the D5 benefits from a compact and robust metal chassis measuring 130 x 80 x 104 mm and weighing 685g, offering an elegant and versatile solution to optimize and centralize the management of an audio system.
