Frequently Asked Questions
How many channels does the WA273 provide?
The WA273 is a dual-channel preamp, allowing you to record two independent sources simultaneously — useful for stereo miking, recording two vocalists, or tracking a mic and DI signal at once.
What type of inputs does the WA273 accept?
Each channel accepts microphone, line-level, and instrument-level signals, making it versatile for vocals, guitars, keyboards, and other sources.
What transformers does the WA273 use?
It uses Carnhill transformers in a fully discrete balanced signal path, which contribute to the warm, harmonically rich character the preamp is known for.
Does the WA273 provide phantom power?
Yes, each channel has independent phantom power for condenser microphones that require 48V.
How much gain does the WA273 offer?
The WA273 provides up to 80dB of gain, which is enough to drive even low-output ribbon and dynamic microphones without needing an external booster.
