Canvas Stereo Dual Line Isolator / D.I.
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.

Canvas Stereo Features:
- Flat frequency response from 20Hz-20kHz
- Converts ¼” unbalanced input to XLR balanced output.
Transformer isolated output. - Sum XLR - Sums the Left and Right XLR outputs together, combining them to form a mono balanced signal if only one XLR input is available at the mixer/interface. The Right XLR out will be disabled, and the combined signal will be on the Left XLR out.
- Sum Thru switch - When engaged (in), Sum connects the left and right thru jacks together to combine the signals for running into a single amplifier (use either thru jack).
- XLR Phase flip - Flips the phase of the Right XLR output relative to the Left, fixing out-of-phase issues in stereo setups.
- Pad: Enables a -15dB input pad (Only in D.I. mode) for reducing hot signals in order to minimize distortion.
- D.I./L.I.: Choose between Direct Injection or Line Isolator modes (Out for DI, In for LI)
- GND Lift: Isolates the GND pin on XLR to help reduce hum if present. Leave out for normal operation.
- Custom wound transformers for low THD (Total Harmonic Distortion) and full frequency response.
Direct Injection:
Line Isolator:
DI or LI?
High Impedance = anything above 1k = Use DI
Low Impedance = less than 1k = Use LI
Troubleshooting:
- Flat frequency response from 20Hz-20kHz
- Converts ¼” unbalanced input to XLR balanced output.
- Transformer isolated output.
- Sum switch: ◦ When disengaged (out), the left input connects to the left thru. The right input connects to the right thru allowing the use of stereo amplifiers. ◦ When engaged (in), Sum connects the left and right thru jacks together to combine the signals for running into a single amplifier (use either thru jack).

- The Canvas comes in a lightly textured matte black enclosure with blue, light green, yellow, orange, red and white ink displaying your painter's palette to begin creating your sonic brush strokes.
- The die-cast enclosure’s exact size is 4.77" x 2.6" x 1.64”.
- Impedance: DI - 10k input, 600 output; LI - 600 input, 600 output
Product Manual

A Canvas for your sonic art

The Canvas Stereo creates a clear pathway for your signal to reach the front of house, interface or powered monitor and rewards your audience with clean, pristine sounds.
The Good Stuff:
Flat frequency response from 20Hz-20kHz
Converts ¼” unbalanced input to XLR balanced output.
Transformer isolated output.
Sum switch:
• When disengaged (out), the left input connects to the left thru. The right input connects to the right thru allowing the use of stereo amplifiers.
• When engaged (in), Sum connects the left and right thru jacks together to combine the signals for running into a single amplifier (use either thru jack).
Pad: Enables a -15dB input pad (Only in D.I. mode) for reducing hot signals in order to minimize distortion.
D.I./L.I.: Choose between Direct Injection or Line Isolator modes (Out for DI, In for LI)
