General

The Walrus Audio Canvas Nano Line Isolator is an ultra-compact line isolator designed for musicians working with limited space on their pedalboard or in mobile setups. This passive LI converts unbalanced signals to balanced signals, giving you an interference-free and transparent sound. Ideal for use with amp-in-a-box pedals like the Walrus Audio ACS1, or when directly connecting active acoustic and bass guitars. Whether you play in a church, a studio or an intimate pub, the Canvas Nano LI guarantees reliable and professional signal transmission.

Canvas Nano Line Isolator: Sublime signal transfer

Thanks to its high-quality transformer and XLR output, the pedal maintains full signal volume while sending your tone clean and balanced to an FOH mixer or audio interface. Less preamplification is required in LI mode, contributing to a natural and dynamic sound. All the essential functions of a professional line isolator are housed in a sturdy, pedalboard-friendly format with the recognisable Walrus Audio look. A smart solution for those who want to leave nothing to chance on the road.

Good product.
I use it to go to a PA from a Tonex peda, which also goes to my guitar amp and cab. The signal it produces is strong and clear better than a DI box.
The size is great and doesn't take up much room on a pedal board.
Great that it doesn't need power.
Feels well made and sturdy.
A few less features than the larger one but not a problem.
I use it in a live environment and it's a great help not having to mic my guitar cab, makes the overall sound better.

Superbe construction avec une qualité sonore au top, bien mieux que mes DI ou d'autres line isolator dans la préservation des aigues et des basses.
J'aurais aimé une sortie thru comme sur sa grande soeur mais c'est déjà très bien.

Un line isolator (isolateur de ligne) vous permet de conserver le niveau ligne en sortie de votre matériel, par exemple un modeleur guitare type ToneX, ACS-1, Iridium, Helix, Pod...qui ne dispose pas de sortie balancée ou de DI.
La différence avec une DI est qu'ici on opère au niveau ligne et pas au niveau microphone (beaucoup moins fort) tout en ayant trois avantages:
- votre signal d'origine est préservé (1:1) et non pas réduit (10:1) au niveau microphone
- votre signal est balancé (ici via la sortie xlr, mais ça pourrait être du TRS) et donc garantie sans interférence sur de longues distances (et en plus vous êtes protégé si le +48v est actif sur la tranche de la table)
- il n'est pas nécessaire d'utiliser le preamp de la tranche du mixeur

Le désavantage est que toutes les tables n'aiment pas un signal ligne via un xlr (certaines tranches ou cartes sons activent automatiquement le preamp micro lorsqu'on passe en xlr) ou bien la table ne gère pas la différence ligne/microphone.
Dans ce cas, deux solutions : utiliser un cable xlr->trs pour entrer en ligne (jack) sur la table et pas en xlr, ou alors baisser son niveau de sortie...rien de grave mais il vaut mieux prévenir la personne qui gère la table (il viendra de toute façon vers vous si le signal est trop chaud).
