WALRUS AUDIO Canvas Stereo Dual Line Isolator/D.I.
CANVAS STEREO
You are the artist. Your sound is the paint, and this is your canvas. After
years of creating tone-painting devices, Walrus Audio is releasing The Canvas
Stereo Direct Box/Line Isolator. The Canvas is designed to remove any
resistance between you and your audience by giving a pristine, sonic
foundation upon which to build your dual-channel masterpiece. From houses of
worship to the dive bar downtown, Canvas Stereo is built to be the performance
palette that goes wherever you are making your music.
DI (Direct Injection) – Use DI mode when connecting an unbalanced, high
impedance source (Electric Guitar, Bass Guitar, etc). The signal will be
reduced by -20dB (-35dB with pad engaged) and converted to a balanced signal
via the transformer connected to the XLR output. Use the gain on your mixer or
preamp to bring the signal up to line level.
LI (Line Isolator) – Use LI mode when connecting your unbalanced, low
impedance source (Amp + Cab Sim like the ACS1, keys, etc.). The signal will
remain full volume and be converted to a balanced signal via the transformer
connected to the XLR output. Less preamp gain will be required in LI mode.
Note – When deciding between DI or LI, check with the manufacturer of
your gear to fi nd the output impedance of the device you are wanting to
interface. For a general guide:
High Impedance = anything above 1k = Use DI Low Impedance = less than 1k = Use
LI
If you lose high-frequency information when using LI mode, then you should
probably be in DI mode. Both left and right channels are affected when using
the DI/LI switch.
PAD – Enables a -15dB input pad (Only in D.I. mode) for reducing hot signals
in order to minimize distortion.
GND LIFT – Isolates the GND pin on XLR to help reduce hum if present. Leave
out for the normal operation.
SUM – When disengaged (out), the left input connects to the left thru. The
right input connects to the right thru allowing the use of stereo amplifi ers.
When engaged (in), Sum connects the left and right thru jacks together to
combine the signals for running into a single amplifi er (use either thru
jack).
THRU – The Thru jack is a pass-through that can be plugged into a guitar amp
or other source.
WHEN TO USE THE CANVAS
Use Canvas Stereo to connect your instrument to a variety of sources. The
following diagrams are a few examples of use cases. Fun tip: The left & right
jacks are independent and can also run two mono sources.
