Speck Electronics EQF 810 Equalizer
The Speck Electronics EQF 810 is a professional single channel analog parametric equalizer and variable filter in a 1/2 rack format. It is simple, it is useful, and it delivers the high quality and specifications found in all Speck Electronics gear. This compact 4-band parametric equalizer has 12 controls for equalization adjustment that covers the audio spectrum from a low 20 Hz all the way up to 25 kHz. To enhance the classic EQ experience, the front panel includes a switch that will select either a "Jensen Transformer-Balanced" or "Active-Balanced" output.
Connect the EQF 810 to virtually any line-level source: balanced, unbalanced, or mixer inserts. The EQF 810 has high headroom that will handle balanced signals up to +28 dBu. Both balanced XLR and balanced 1/4" jacks are provided for signal connections to and from the EQF 810.
4 Sweepable Bands:
- L Band - a low band that sweeps the low frequencies from 20 Hz - 400 Hz, this band offers a Peak/Shelf select switch
- L/M Band - a switchable low and mid band, this fully parametric section can be switched between a low-frequency band that sweeps from 40 Hz - 800Hz, or a mid-frequency band that sweeps 400 Hz - 8 kHz, this band has a variable bandwidth adjustment
- M Band - a fully parametric mid band with a frequency sweep range from 400 Hz to 10 kHz
- H Band - a high band that adjusts the high frequency from 1.5 kHz all the way up to 25 kHz, this band also offers a Peak/Shelf select switch
