FU-EQ215 – Dual 15-Band Graphic Equalizer
Professional tone shaping for live sound, studios, and installations.
Professional Dual 15-Band Graphic Equalizer for Live and Studio Applications
The FU-EQ215 dual 15-band graphic equalizer is engineered to deliver precise tonal shaping and reliable signal control in professional audio environments. Designed for live sound engineers, studio technicians, and installation professionals, this unit offers ±12dB of boost or cut per band across two independent channels. Whether correcting room acoustics or refining instrument tone, the FU-EQ215 gives you immediate, tactile control over your sound.
With an extended frequency response and low total harmonic distortion of just 0.05% at 1kHz, this dual 15-band graphic equalizer ensures clarity without coloration.
Each channel of the FU-EQ215 features 15 frequency bands with ±12dB adjustment, allowing precise frequency sculpting. The integrated low-cut switch eliminates unwanted rumble and subsonic noise, improving system clarity and protecting speakers from excessive low-frequency energy.
Balanced XLR and ¼” TRS inputs and outputs guarantee clean signal transmission with minimal noise, even across long cable runs. A signal-to-noise ratio exceeding 90dB ensures that adjustments remain transparent and professional.
Bright LED level indicators provide immediate visual feedback, while bypass and in/out controls allow instant comparison between processed and unprocessed audio — an essential feature for accurate tuning.
Imagine walking into a venue with problematic acoustics. Low-end buildup, harsh upper mids, feedback creeping in. Instead of fighting the system, you shape it. The FU-EQ215 dual 15-band graphic equalizer allows you to surgically remove troublesome frequencies, enhance warmth, and balance vocals and instruments with confidence.
In studio settings, it becomes a tonal sculpting tool — subtle adjustments that refine a mix without digital artifacts. Its rugged rack-mount chassis makes it equally at home in touring rigs or permanent installations. And with universal 110V–220V compatibility, it performs reliably anywhere in the world.
This is not just EQ. It is control, transparency, and precision in physical form.
Upgrade your signal chain with the FU-EQ215 dual 15-band graphic equalizer and experience professional-level tonal control. Perfect for live sound reinforcement, recording studios, rental companies, and installed systems, it delivers clarity, flexibility, and dependable performance every time you power it on.
Take command of your frequencies. Shape your sound with confidence.
