Walrus Audio Canvas Mono Line Isolator/D.I.

From Walrus Audio:

"Canvas Mono is a Passive Line Isolator (LI) and Direct Injection (DI) device that converts your unbalanced signal into a balanced signal 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 , or running an acoustic or bass guitar direct, then the Canvas Mono is your new bridge to the front-of-house. The Canvas Mono packs everything you need from a DI/LI into a standard pedal-sized enclosure designed to look great right on top of your board.

Canvas Mono Features

• Flat frequency response from 20Hz-20kHz

• Converts ¼” unbalanced input to XLR balanced output.

• Transformer isolated output.

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

• 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 DI or LI (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: 

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.

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."
