API3122V 2-Channel Mic/Line Pre With Variable Output and High-Pass Filter
1/2
Independent shopping perspective
The Korena take
Two channels of mic/line preamplification are paired with selectable front- or rear-panel XLR and 1/4-inch inputs. Gain and Variable Output Level controls work alongside a fixed-frequency high-pass filter, 48 V, polarity, and pad functions. The 3122V uses 2520 Op-Amps and proprietary output transformers, adds a 3:1 output-transformer tap, and gives each channel analog VU metering with a separate peak LED for visible level monitoring.
Strong match
Who this is for
- Two-channel input setups needing selectable front or rear XLR and quarter-inch connections.
- Monitoring XLR output level on analog VU meters with separate peak indication.
Consider the trade-offs
When to look elsewhere
- Setups requiring more than two preamp channels from one unit.
