Walrus Audio released the Canvas Series Line Isolator DI in mono and stereo versions, the company's product pages show. Gearnews reported the pair on 12 April 2022, describing them as "two distinct flavours, mono and stereo"¹.

Both units are passive devices that convert a ¼ inch unbalanced input to a transformer-isolated XLR balanced output, with a flat frequency response from 20Hz to 20kHz²³. A D.I./L.I. switch selects between Direct Injection mode, where the signal is reduced by -20dB (-35dB with the pad engaged), and Line Isolator mode, where the signal stays at full volume and less preamp gain is needed at the mixer²³. Walrus gives the impedance as 10k input and 600 output in DI mode, and 600 input and 600 output in LI mode²³. Both have a -15dB input pad that works only in D.I. mode, and a ground lift switch that isolates the GND pin on the XLR to help reduce hum²³.

The mono unit's Sum switch turns the Thru channel into a second input when engaged, allowing a stereo input signal to be summed to the XLR output³. The stereo unit adds a Sum XLR switch, which combines the left and right XLR outputs to a mono balanced signal on the left XLR out and disables the right, and an XLR phase flip that inverts the right output relative to the left². Its Sum Thru switch connects the left and right thru jacks for running into a single amplifier; disengaged, the inputs pass to their respective thru jacks for stereo amplifiers². Both use custom-wound Sapphire Transformers, which Walrus says are wound for low total harmonic distortion and full frequency response²³. The die-cast enclosure measures 4.77 by 2.6 by 1.64 inches²³.

Gearnews gave the prices as "RRP, MONO USD 149 or Stereo USD 249"¹. Walrus lists the mono at $149.99 and the stereo at $249.99²³. Walrus covers all its products with a limited lifetime warranty³.
