Features
5-band EQ preamplifier: adopt 5PCS JRC4558 op amp, each one is responsible for one frequency band and process the audio signal independently. 5-band separate control knob, easily to control and set the freqency range as you like.
Bypass design suits more use: with bypass button to turn off EQ preamplification, the audio signal will output from IN to OUT directly without any processing, convenient to enjoy original sound.
Attractive looking and powerful design: all metal case and gold-plated PCB panel, aluminum knurled knob, all I/O interfaces are gold-plated to ensure the tight connection and smooth transmission of the original audio signal and minimizes the loss of the signal.
Mini size and powered by DC 5V: compact design easy to carry, convenient to use in most scenarios, no need to bring a separate power supply, very suitable for daily needs of most users.
Warm tips:
1. Without power adapter, and EQ5 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 please don't connect RCA and 3.5mm AUX input at the same time avoid mixing.
3. EQ preamplification function need to connect to DC 5V power adapter, EQ5 can work normally without power supply in bypass mode.
