Walrus Audio / Canvas Line Isolator/D.I. [WAL-CANV/M]

This passive direct box (DI)/line isolator is based on the concept of a ""white canvas that perfectly reflects the sound you envision.""

The Canvas Mono is a passive line isolator (LI) and direct injection (DI) device that converts unbalanced signals to balanced signals and transmits them to FOH recording interfaces and mixers. If you're using an ""Amp in a box"" like the ACS1 to output acoustic or bass guitars directly to a mixer or interface, the Canvas Mono will be your new weapon.

Direct Injection Mode

Use DI mode when connecting high-impedance sources (1,000Ω or more, such as electric guitars and basses) with unbalanced signals. The signal is reduced by -20dB (-35dB when using the PAD) and converted to a balanced signal via a transformer connected to the XLR output. Boost the signal to line level using the gain on your mixer or preamp.

Line Isolator Mode

Use LI mode when connecting low-impedance sources (1,000Ω or less) with unbalanced signals (such as amp + cabinet simulators like the ACS1, synthesizers, etc.). The signal remains at full volume and is converted to a balanced signal via a transformer connected to the XLR output. This reduces the required preamp gain.

FEATURE

? Flat frequency response (20Hz?20kHz).

? SUM switch: The thru channel becomes a second input, allowing simultaneous output of stereo input signals aligned with the XLR output.

? PAD switch: Enables a -15dB input pad (D.I. mode only) to reduce hot signals and minimize distortion.

? D.I./L.I. switch: Selects between DI (Direct Injection) mode and LI (Line Isolator) mode.

? GND Lift: Isolates the XLR GND pin to eliminate hum noise if it occurs.
