- 7-Band EQ for Custom Sound: EQ7 stereo equalizer lets you tailor sound around your speakers, music and taste. Built for more detailed tone control, it offers seven adjustable bands from 32Hz to 10kHz with ±10dB adjustment to shape bass weight, vocal body and treble detail.
- True Balanced XLR Conversion: EQ7 actively converts RCA input into true balanced XLR output with positive and inverted signal phases, bridging classic RCA sources with balanced HiFi amplifiers and powered speakers through a cleaner, lower-noise signal path with better signal integrity.
- Dual Large VU Meters in Motion: Watch your signal come alive through classic needle movement, adding a retro feel while making music dynamics easy to see at a glance. Brightness, speed and gain controls let you fine-tune the meter glow and response to match your source level and preferred visual style.
- Flexible RCA/XLR Connectivity: Keep DAC, CD player or streamer connected through RCA/XLR inputs and switch sources without repeated cable changes. Simultaneous RCA/XLR outputs share the EQ-tuned signal, while the volume knob keeps final level control close at hand.
- Compact Aluminum HiFi Build: CNC-machined aluminum front panel, aluminum chassis and gold-plated I/O connectors give EQ7 a sturdy, refined build with reliable signal contact. Its compact footprint fits easily into desktop, bookshelf or HiFi rack systems, while USB-C power keeps connection simple.

FAQs
Q: Is the XLR output true balanced?
A: Yes. EQ7 uses a dedicated circuit to convert the processed audio signal into a true balanced XLR output (with opposite-phase signals), helping to minimize noise and maintain signal integrity.
Q: Does the EQ7 support simultaneous RCA and XLR output?
A: Yes. Whether the input is RCA (unbalanced) or XLR (balanced), the signal is processed by the EQ and then output through both RCA and XLR at the same time. The two outputs cannot be switched independently.
Q: Does the EQ7 have a bypass function?
A: There is no dedicated bypass switch. However, setting all EQ controls to the center position (0 dB) achieves a near-bypass effect, with no gain or attenuation applied.
Q: What if the VU meter response is too strong or too weak?
A: Adjust the VU meter sensitivity and range controls on the rear panel. Fine-tune these settings while playing audio to achieve the desired display effect.
Q: What power supply should be used?
A: Please use the included power adapter. If using another adapter, make sure it is a high-quality 5V DC power supply. Do not use fast-charging adapters, as they may affect performance or cause damage to the EQ7.
