EQ5 PRO 5-Band Analog Preamp Bluetooth Receiver Stereo Audio Processor VU Meter

Item description

Features

  • 5-band EQ equalizer and preamp: separate and rich frequency band controls (100Hz / 400Hz / 800Hz / 4KHz /10KHz ), each band is processed by one op amp independently. EQ5-PRO can compensate for the defects of speakers and sound field by adjusting 5-band high, middle and low frequencies, and modify various sound sources. 
  • Vintage VU meter and Bluetooth input: with dual large VU meters (45mm), driven by a dedicated VU driver chip to show the level of audio signal accurately in real-time, dynamically decorate audio environment and provide incomparably 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 to enjoy 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 minimizes the loss of the signal. Mini size and powered by DC 5V, easy to carry and convenient to use in most scenarios.

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 signal mixing.
3. EQ5-PRO can input and output audio signal without power supply in bypass mode, but the signal without any preamplification, the VU meters also don't work.
