Exploring the UA Precision Delay Mod

In this video, sponsored by Universal Audio, Eli Krantzberg looks at the Precision Delay Mod plug-in on a clav track and a rhythm guitar track.

Precision Delay Mod

The Precision Delay Mod, part of the Precision Mix Rack Collection, is an interesting stereo delay processor with modulation.

What makes it interesting, I think, is the ability to control the amount of delayed signal routed back to its input (feedback) in both positive and negative values.

With positive values, the polarity of the feedback signal is in phase with the original source signal.

With negative values, the polarity of the feedback signal is inverted.

The same applies to the mix knob. The delays can be mixed with the original signal either in phase or out of phase by any amount you want. This allows for some interesting effects.

Modes & LFO

Precision Delay has five modes of operation. In addition to three delay styles (dual delay, Xover delay, and ping pong delay), it also offers chorus and flanger modes.

There are six LFOs to choose from in the modulation section. A sine wave or a triangle wave, starting at different positions in their cycle.

Modulation, as well as the delays, can be synced to tempo. So, the mod section works great for a subtle type of movement, or faster more deliberate oscillation rates for a more noticeable effect.


Hear it in action in this video on a clavinet track first, and then on a rhythm guitar track.
