SA240 Mercury Flanger User’s Guide 16
uses extremely low noise buffers, which provide a very low output impedance and are effective for
driving long cables or long chains of effects following the Mercury’s audio output.
Out of the box, the Mercury operates in true bypass mode. In order to switch to buffered bypass
mode, edit the Mercury’s global settings using the Neuro App.
We recommend you choose between the active analog bypass (a.k.a. buffered bypass) and relay-
based true bypass based on what is needed in your signal chain. Ideally, the first pedal in a signal
chain is a buffered input followed by true bypass in the rest of the signal chain.
Both bypass methods have pros and cons associated with them. Buffered bypass provides consistent
input impedance so that if the source is susceptible to variations in input impedance (similar to a
guitar pickup), there won’t be a noticeable change in tone. True bypass has the benefit of providing a
dedicated hardwired bypass signal path. The Mercury features small-signal relays for true bypass
switching that offer reduced pops and clicks compared to the traditional true bypass switching
method using a mechanical switch.
Stereo Routing
The Mercury works great as a mono flanger effect, but its stereo inputs and outputs also make it a
true stereo effect as well as a flexible signal router. It can act as a stereo splitter, merger, or true
stereo effect, and it can also be set up in a number of other unique signal routing modes.
By default (as of firmware version 1.06), the hardware will automatically set the routing mode by
detecting cables connected to the inputs and outputs. If, for example, cables are connected to INPUT
1 and OUTPUT 1 only, then the routing mode will be set to Mono In, Mono Out. If cables are
connected to INPUT 1, OUTPUT 1, and OUTPUT 2, then the routing mode will be set to Mono In, Stereo
Out. If cables are connected to INPUT 1, INPUT 2, OUTPUT 1, and OUTPUT 2, then the routing mode will
be set to stereo in, stereo out. Other routing options are available via MIDI or the Neuro App.
A few different routing options are displayed below. The right side of each diagram shows inputs 1
and 2, the left side shows outputs 1 and 2, and flanger effects A and B are in the center.
