602/1202/2402 Power Amplifiers
P.I.P.-FXT uses balanced 1:1 transformers to isolate the
source from the inputs. It comes with balanced female 3-
pin XLR connectors.
P.I.P.-PA permits the unique capability of adding one mic/
line input directly to each channel of an amplifier. With phan-
tom power for microphones, this mic/line input may be re-
motely switched from mic to line priorities.
P.I.P.-RPA A phantom-power mixer that has four balanced
mic or line inputs with voiceover capability and adjustable
"duck" level, 84 dB of attenuation. A 10-volt DC source for
remote control capability is provided. The P.I.P.-EXT (Part
M44731-4), available from service, allows the P.I.P.-RPA and
other PIP cards to be "extended" outside the amplifier for
easy set up.
P.I.P.-RPAT has the same features as the P.I.P.-RPA but in-
cludes four input transformers.
P.I.P.-XOV is a versatile, economical mono 12- or 18-dB/
octave crossover/filter which offers bi-amping and tri-amping
capability.

8.2 Cooling Fan Options
Every Macro-Tech amplifier has a built-in high-velocity
fan that provides optimum cooling. Two optional re-
placement fan blades are available for special cooling
requirements. Crown part C 6594-3 is a quieter, low-ve-
locity fan blade that in many cases can provide ad-
equate cooling. Crown part C 6593-5 is a reverse
air-flow fan blade which changes the direction of the air
flow in and out of the amplifier (not recomended for the
Macro-Tech 2402). Important: The optional replacement
fan blades should only be installed by a qualified tech-
nician.
8.3 Level Control Shaft Lock
A security accessory, the shaft lock can be used to se-
cure your amplifier's level controls in situations where
the front panel controls are subject to tampering. One is
needed for each channel. They can be ordered through
the Crown Service/Parts Department. For more informa-
tion, contact your local Crown dealer or Crown's Techni-
cal Support Group.
