Notes: Consider this your clean slate. The Canvas Stereo is a Direct Box/LIne Isolator designed to remove any resistance between you and your audience by giving a pristine, sonic foundation to build your stereo masterpiece upon. From houses of worship to the dive bar downtown, Canvas Stereo is built to be the performance tool that goes wherever you are making your music.

Canvas Stereo is a Passive Line Isolator (LI) and Direct Injection (DI) device that converts your unbalanced signals into balanced signals for interfacing properly with your recording interface or mixer at front-of-house. If you're using an amp-in-a-box (DSP Guitar Rig), like our ACS1, keyboards, or any other instrument utilizing both left and right outputs, then the Canvas Stereo is your new bridge to the front-of-house. The Canvas Series DIs pack everything you need from a DI/LI into a standard pedal-sized enclosure designed to look great right on top of your board.

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 up to line level.

Line Isolator:
Use the LI when needing to connect your unbalanced, low impedance source (Amp + Cab Sim like the ACS1, keys, etc.). The signals will remain full volume and be converted to balanced signals via the transformer connected to the XLR output. Less preamp gain will be required in LI.

DI or LI?
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 DILow Impedance = less than 1k = Use LI .

Troubleshooting:
This is a passive device, so you will not damage anything if connected improperly, but it could affect the signal level and frequency response if not connected properly. This is an easy thing to test since the LI/DI switch is built into Canvas. If you lose high-frequency information when using LI mode, then you should probably be in DI mode.

Notes: Adding another tool to the musical paint pallet, Walrus Audio is creating another way to design your tone with the Canvas Series Passive Re-Amp. The Re-Amp is a studio tool designed to send recorded guitar, drums, or other instrument tracks from your recording session through pedals and effects, or different amp combinations. The Re-Amp makes it's appearance to facilitate all-new ways to experiment with your songs.

Artists and producers can save time on tracking sessions by recording dry tracks first, then using Canvas Re-Amp's custom transformer to convert line-level signals, optimizing them to work with amps and guitar pedals of any kind to explore limitless tones and sounds.

Using a Re-Amp

1. From your DAW, audio track goes into the Canvas Re-Amp.
2. Out from Re-Amp into pedals or mic'd amp.
3. Out from pedals / amp back into DAW.

Notes: Make your professional audio devices Bluetooth compatible with the ART BT-DI, a rugged and flexible Bluetooth Audio DAC. The BT-DI is designed to provide a reliable Bluetooth interface from computers, phones, and legacy Bluetooth devices to any installation. Working as a remote extension of your mixer and mic outputs, the BT-DI utilizes phantom power, so an external power supply is not required.
