The Model ASC is a professional single channel 4 band equalizer in a 1/2 rack format. The Speck Model ASC is reminiscent of vintage equalizers, revered for their dynamic range and musical performance.
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.
There is a - 12/+6 dB gain control that handles the level variations when patching between balanced and unbalanced gear. A bypass switch silently removes the equalizer from the audio path.
Connect the ASC to virtually any line level source: balanced, unbalanced, or mixer inserts. The Model ASC has high headroom that will handle balanced signals up to +28dBu.
Under normal operating conditions, both versions sound about the same. The transformer (Jensen Transformer) does add a subtle texture to the overall sound. It sounds different than the active-balanced output (the sonic difference is kinda hard to describe).
Both outputs have a "clean & clear" sound. Although, when the transformer version is pushed to its maximum output limits, the transformer will exhibit a slight, almost soft distortion at low frequencies. That's the transformer sound!
The "ASC-T" features both transformer and non transformer balanced outputs (the "TRS" output can be run either balanced or unbalanced... and can be used simultaneously to avoid DAW latency if desired.
ASC or ASC-T?
The main difference between the ASC and the ASC-T is that the ASC-T has the choice of a transformer or transformerless output where with the ASC you only have transformerless output. There is a distinct sonic difference between going through the transformer and going transformerless... with the ASC-T you get the choice of two sonic output differences.
