The Lino is perfect as a preamplifier for connecting to high resolution (192 kHz / 24 bit), balanced-input analog to digital converters (ADCs). The Lino’s Flat output used in conjunction with Channel D’s Pure Vinyl™...
The Balanced outputs also can be configured as standard RIAA phono preamplifier outputs via an internal jumper setting. If necessary, XLR pin 3 may safely be connected to circuit common / ground, as the Lino has servo balanced (ground sensing) outputs.

Securely connect the chassis ground wire from your turntable / tonearm (if so equipped) to the grounding lug on the rear panel of the Lino. If your turntable doesn’t have a grounding connection, leave this terminal disconnected. Important: only connect the ground to a turntable chassis or ground wire, not to a ground connection on any other equipment.

Disconnect the Lino power supply before making these configuration settings. Lino preamplifiers ordered in a configuration omitting the RIAA EQ module will not include these jumper settings and will be connected for Flat balanced outputs. An external analog to digital converter (ADC) and Pure Vinyl would be required to provide the necessary RIAA EQ.
If you’re accustomed to using conventional phono preamplifiers, the Lino “Flat” gain settings may seem somewhat lower than usual. The gain settings are tailored to using the Lino with Channel D Pure Vinyl’s RIAA EQ compensation curve and an analog to digital converter. The required gain is about 10 to 12 dB less than needed in a conventional phono preamplifier, because the signal is provided to Pure Vinyl with treble emphasis...
• If the levels are too low, increase the gain on the Lino. (For monitoring / playback, if the output levels of your interface can be adjusted independently of the input levels, use the +4 dBu setting for the output.)
This will likely cause hum with the Lino (or any other balanced phono stage). This is not a fault of the Lino; it is a problem with the tonearm wiring, which is not configured properly for use with a balanced input.
Warranty • One year parts and labor, limited warranty. In the unlikely event your Lino must be returned to Channel D for repair, contact Channel D in advance for a return material authorization number and shipping instructions.
