Speck Electronics EQF 810


What is the EQF 810?

The EQF 810 is a professional single channel analog parametric equalizer and variable filters 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 20Hz all the way up to 25kHz.

To enhance the classic EQ experience, the front panel includes a switch that will select either a “Jensen Transformer-Balanced” or “Active-Balanced” output.

The Rear Panel

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 +28dBu.

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 20Hz – 400Hz. 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 40Hz – 800Hz, or a mid frequency band that sweeps 400Hz – 8kHz. This band has a variable bandwidth adjustment.

M Band – a fully parametric mid band with a frequency sweep range from 400Hz to 10kHz.

H Band – a high band that adjusts the high frequency from 1.5kHz all the way up to 25kHz. This band also offers a Peak/Shelf select switch.

2 Variable Filters

Low Pass – A variable 12dB/Octave filter with Bypass switch is adjustable from 150Hz to 25kHz.

High Pass – A variable 12dB/Octave filter with Bypass switch is adjustable from 20Hz to 250Hz. The 5X switch will change the adjustable range from 100Hz to 1.2kHz.
