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 Mono 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 single-channel masterpiece. From houses of worship to the dive downtown, Canvas Mono is built to be the performance palette that goes wherever you are making your music.

INSTRUCTIONS

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 find 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.

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 normal operation.

SUM

• Sum switch turns the Thru channel into a second input when engaged, allowing stereo input signals to be summed to the XLR output.

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 Mono to connect your instrument to a variety of sources. The following diagrams are a few examples of use cases.
