Douk Audio EQ5-TONE Mini 5-Band EQ Equalizer with Bluetooth Receiver Stereo Audio Preamp w/VU Meter
Warm Tips1.Without a power adapter, EQ5-TONE needs to be powered by separate USB power supply. Don't use the USB port of computers or share the power supply with audio source, otherwise common ground noise will be caused.2.Stereo RCA and 3.5mm AUX input are in parallel, two inputs and outputs will work simultaneously, So to avoid signal mixing, please don't connect RCA and 3.5mm AUX input at the same time.3.EQ5-TONE can input and output audio signal without power supply in bypass mode. However, if the signal hasn’t been preamplified, the VU meters will not function. Features 5-band EQ equalizer and preamp: separate and rich frequency band controls (75Hz/400Hz/ 800Hz/4KHz/10KHz), each band is processed by one op amp independently. EQ5-TONE can compensate for the defects of speakers and sound field by adjusting 5-band high, middle and low frequencies, and modify various sound sources. Adjustable VU meter and Bluetooth input: Dual large VU meter (45mm), driven by a dedicated VU driver chip, supporting the adjustment of background light, pointer speed and Gain, dynamically decorates audio environment and provides incomparable visual effects. Add Bluetooth 5.0 input, convenient for you to enjoy HIFI music via wireless connection. Bypass design and balance adjustment: with bypass mode to turn off EQ preamplification, the audio signal will output from IN to OUT directly without any processing, convenient for enjoying original sound. Also with a balance control to compensate for the left and right channel of all outputs and prevent the sound field positioning from deviating from the center position. Attractive looking and powerful design: all metal case and aluminum knurled knob with good shielding performance, all I/O interfaces are gold-plated to ensure the smooth transmission of the original audio signal to minimize the loss of the signal.
