Normal-Hi-Fi Installation; Cleaning - Crown D-150 Service Manual

3.12 NORMAL HI-Fi INSTALLATION
1.
Two-conductor speaker cables must connect to the OUTPUT
dual binding posts using terminal lugs, tinned ends, or the
special "banana" plugs supplied with the D-150. Connect the
in-line fuses as recommended in the Accessory Bag and Figure
3-16.
: Since the D-150 is a"basic amplifier," the main outputs of the
control-center or "preamplifier" must be connected via
shielded eudio-cables to the two jacks marked INPUT. Use
RCA-pin. at preamp. and standard./-in. phone-plug at the D-
150.
The two cables should be tied parallel along their entire length
using the accessory cable ties.
. U/L requirements prefer a 3-wire AC power connector; how-
aver, proper Corrections to a switched' outlet on the contrat
center requires the use of a 3-to-2 wire adapter. NOW, plug the
AG:into a switched outlet on the contro! center. *

4. Your Control Center may now be turned on. Then advance the
D-150 Input-Gain Controls about 4-open (150° clockwise).
When using the CROWN IC-150 Control-Center, the LOUDNESS
should attain almost full rotation (2 to 4 o'clock) for loudest
"concert-hall" volume. If at 3.o'clock the volume is low, increase
the 0-150 input gain controls; if too high, decrease the 0-150
gains.
3.13 CLEANING
The CROWN D-150 has a rugged anodized front panet (optional)
for life-time service. The panel can be cleaned with a moist cloth
and mild detergent. Never use steel wool, scouring powder, lye
solution, or arly strong abrasive cleaner as these will damage the
panel's-tinish.
The chassis should require no more cleaning than periodic dust-
ing with a clean dry cloth.
