How do I set up my TLA-50 for vocals?

Send the output from a microphone preamplifier such as the 2BA-221 into the XLR +4dB input on the TLA-50 and the XLR output into the input to your live sound or recording system making sure that input is set up for +4dB level input (if it is set for -10dB only, use the TRS 1/4 inch output instead). Set the gain on the TLA-50 to 3, set the attack and release controls to medium (middle position) and the meter to Reduction. Increase the Gain Reduction control until the meter is reading around 3-4 dB of gain reduction.
