1. IEC AC POWER INLET
Connect the accompanying power cord to power the unit.
2. 250v Fuse
Always use the correct fuse rating, as indicated beside the fuse holder. Warm Audio provides an extra
fuse located inside the IEC inlet.
3. Ground Lift Switch
Eliminates unwanted hum and buzz by interrupting the ground loops between equipment, preventing
current flow along the cable shield between two devices.
4. Balanced Line Outputs (XLR & TRS)
Balanced output are provided on an XLR and ¼" TRS connection for convenience. Unbalanced opera-
tion is possible via ¼" TRS output using an unbalanced ¼" cable.
5. Insert (Send & Return)
These connects are designed to allow another device such as a compressor or EQ to be inserted in the
middle of the WA73's circuit. These connections insert the secondary device into the circuit after the
input transformer and initial gain stage. We recommend unbalanced ¼" patch cables.
6. Line Input
This TRS input is padded and is designed for line level instruments or sources that put out line level
signals such as keyboards, electric instruments or audio interface outputs. This input travels through the
entire preamp circuit including both Carnhill Transformers.
7. Microphone XLR Input
This input is designed for dynamic, condenser and ribbon microphones. Other instruments or devices
that put out a low level microphone signal can also be plugged into this input. The input impedance
can be set to either 1200 or 300 ohms, via the tone button.
