CA2
Output level is controlled by the rotary Volume
control on the front of the unit, the position of
which is indicated by a black pointer. Rotating the
control clockwise will increase the output level. It
is good practice to lower the volume setting before
switching on the preamplifier or any associated
equipment, or while changing the input selection.
Unity gain though the CA2 from any of the line
level inputs is indicated by the ‘0dB’ print on the
front panel, beside the volume control. This is the
volume position the preamp should be set to for
‘Home Cinema Bypass’ so the CA2 has no
influence on signal level when used within a cinema
surround system.
Due to the nature of the electronics in ATC
amplifiers it is quite normal for a sound to be heard
from the speaker when the power is applied or
disconnected. The noise heard will not damage the
speaker and is quite normal. Although ATC uses the
highest-grade components, a different noise may be
heard from each speaker due to slight tolerance
variations in the amplifier components.
