•     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 Sapphire 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 up to line level.

Line Isolator: 
Use the LI when needing to connect your unbalanced, low impedance source (Amp + Cab Sim like the ACS1, keys, etc.). The signals will remain full volume and be converted to balanced signals via the transformer connected to the XLR output. Less preamp gain will be required in LI mode. 

DI or LI?
When deciding between DI or LI, check with the manufacturer of your gear to find the output impedance of the device you are wanting to interface. For a general guide:

High Impedance = anything above 1k = Use DI
Low Impedance = less than 1k = Use LI

Troubleshooting:
This is a passive device, so you will not damage anything if connected improperly, but it could affect the signal level and frequency response if not connected properly. This is an easy thing to test since the LI/DI switch is built into Canvas. If you lose high-frequency information when using LI mode, then you should probably be in DI mode.

• 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).
