The CH Precision L1.5 is fully DC-coupled. No coupling capacitors in the signal path.
Instead, CH Precision’s DC-compensation architecture continuously monitors DC conditions and applies ultra-slow correction currents outside the direct signal path.
This allows the L1.5 to preserve the advantages of direct coupling while maintaining stable, silent operation.
A dedicated setup wizard also accounts for system cabling, helping preserve correct behavior in the actual installation.
Direct connection.
Intelligent correction.
Analog purity preserved.
