Unison Features
Unison technology enables these Arrow features, all with Realtime UAD Processing:
• Alternate microphone preamplifier sound – Arrow's ultra-transparent mic preamps
inherit all the unique sonic and input characteristics of the emulated hardware
preamp, guitar amp, or pedal, including the mic, line, and Hi-Z inputs.
• Realistic tandem control – Unison facilitates seamless interactive control of
Unison preamp plug-in settings using Arrow's digitally-controlled hardware and/
or the plug-in interface. All equivalent preamp controls (gain, pad, polarity, etc)
are mirrored and bidirectional. The preamp controls respond to adjustments with
precisely the same interplay behavior as the emulated hardware, including gain
levels and clipping points.
• Hardware input impedance – All Arrow preamps feature variable input
impedance in analog hardware that can be physically switched by Unison plug-
ins for physical, microphone-to-preamp resistive interaction. This impedance
switching enables Arrow's preamps to physically match the emulated unit's input
impedance, which can significantly impact the sound of a microphone. Because
the electrical loading occurs on input, prior to A/D conversion, the realism is
faithful to the original target hardware preamp.
• Tactile gain staging – Arrow's top panel preamp knob can independently adjust
all gain and level parameters available within the Unison plug-in via
Mode. The gain stage being adjusted can be remotely switched via Arrow, so
multiple gain levels and their associated colorations can be tuned from the
hardware knob for precise physical tactile control, all without using the Unison
plug-in's software interface.
