Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
1. Total System Gain consists of: Wideband System Gain + High and Low Independent Channel Gains + Converter Gain.
Total System Gain is calibrated during Cal/Config process.
2. Sample tested.
3. Volume control is log taper, trimmers are linear taper.
