Walrus Audio 873371-01U Canvas Mono Line Isolator and Passive DI Box
Product Information: Canvas Mono Direct Box/Line Isolator
The Canvas Mono Direct Box/Line Isolator by Walrus Audio is a versatile device
designed to provide a pristine, sonic foundation for your single channel
masterpiece. It allows you to connect your instrument to a variety of sources,
making it suitable for use in live performances, studio recordings, and other
musical settings.
The Canvas Mono features the following key components and
functionalities:
- LI (Line Isolator) mode: Use LI mode when connecting an unbalanced, low impedance source such as an Amp + Cab Sim or keys. The signal will remain at 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.
- DI (Direct Input) mode: Use DI mode when connecting a high impedance source. The Canvas Mono provides a suitable impedancematch for sources with an output impedance above 1k.
- Thru jack: The Thru jack allows for a pass-through connectionto a guitar amp or other source.
- Limited lifetime warranty: This product comes with a limited lifetime warranty for added peace of mind.
Please refer to the manufacturer of your gear to determine the output impedance of the device you are connecting to the Canvas Mono. Use the following guidelines to decide between DI and LI modes:
- High Impedance: Use DI mode for sources with an output impedance above 1k.
- Low Impedance: Use LI mode for sources with an output impedance below 1k.
If you experience a loss of high-frequency information when using LI mode, it
is recommended to switch to DI mode.
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 bar downtown, Canvas Mono is built to be the performance palette that
goes wherever you are making your music.
Important instruction
- 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.
