High Prelormance Valve Preamplifier CTA305 For low
level voltage amplification valves are in a league of their
own With respect to linearity and musicality For nearly a
decade, COPLAND has contributed to the refinement of
amplification uSing these classic devices.

The CTA305 employs highly reliable 6922 valves selected
after ageing to assure optimal compatibility Each class A
line level amplifier circuit is diVided into two separated non-
inverting units This allows us to use much less complex
circuit, with increased stability, and no requirement for
internal lag compensating networks.

Discrete DC power supply regulators designed for nearly
zero output impedance isolate individual gain stages from
each other

in addition to the five sets of line level inputs, the CTA305
offers a high quality phono amplifier.

For the listener With a large investment in LP-˜s, this amplifier
provides an opportunity to recover musical pleasures and
more nuances from irreplaceable recordings.
