What is the ASC-V ?
The ASC-V is a professional single channel 4-band equalizer in a 5.25” vertical module compatible with API Audio® 500 series rack frames. 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 25Hz all the way up to 25kHz. To enhance the classic EQ experience, the ASC-V offers both transformer-balanced and active-balanced outputs.
4 Sweepable Bands
L Band - a low band that sweeps the low frequencies from 25Hz - 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 2kHz all the way up to 25kHz. This band also offers a Peak/Shelf select switch.

The Rear Panel
In addition to the standard rack friendly edge connector, the ASC-V has a set of 1/4" TRS input/output jacks, and a power input connector. With these I/O connectors and the optional power module, you can ignore the PC edge connector and use the ASC-V as a stand alone EQ.

We even offer a mounting base that will hold a single EQ or a pair of the ASC-V's.
