REVIEW SECTION
I. Introduction
This manual contains complete service information on
the D- 150A. It is designed to be used in conjunction with
the D- 150AInstruction Manual. However, some
important information is duplicated in this Service
Manual in case the Instruction Manual is not readily
available.
NOTE: THE INFORMATION IN THIS MANUAL
IS INTENDED FOR USE BY AN EXPERIENCED
TECHNICIAN ONLY!
II. Warranty
As aCrown Warranty Service Station, you should be
familiar with Crown warranty policies. Each Instruction
Manual contains basic policies as related to the customer.
However, under questionable circumstances, please
contact the Technical Service Department or Director of
Customer Service at: Crown International, Inc., 1718
W. Mishawaka Road, Elkhart, IN 46517.
III. Specifications
General Specifications
Hum and Noise (20Hz-20KHz): HOdB below rated
output.
Phase Response: +0, -15°, DC-20KHz at 1watt.
Input Impedance: 25K ohms, ±3%.
Amplifier Output Protection: Short, mismatch, and
open circuit proof. Limiting is instantaneous with no
flyback pulses, thumps, cutouts, etc. No premature
limiting on transients.
Overall Protection: AC line fused. Thermal switch in AC
line protects against overheating caused by insufficient
ventilation. Controlled slewing-rate voltage amplifiers
protect overall amplifier against RF burnouts. Input
overload protection is furnished by internal resistance at
inputs of amp.
DC Output Offset (Shorted Input): 10 millivolts or less,
internally adjustable to zero.
Turn-On: Instantaneous, with minimum thumps and no
program delay.
Circuit: Wideband multiple feedback loop design
utilizing one linear IC (dual op-amp), total equivalent of
48 transistors, 22 signal diodes, 3zener diodes, and 6
rectifier diodes.
Power Supply: Massive computer-grade filter
capacitors store over 20 joules of energy. Two regulated
supplies for complete isolation and stability.
Power Requirements: Requires 50-400Hz AC on H)0,
200, 220, or 240V ±10% operation. Draws 30 watts or less
on idle, 250 watts at 160 watts total output.
Heat Sinking: The entire amplifier is used as aheat sink.
3/16 inch thick chassis acts as aheat sink along with
auxiliary fins.
Chassis: All aluminum construction for maximum heat
conduction and minimum weight.
Controls: Independent level controls are mounted on the
front panel. Power switch with associated pilot light is on
front panel. Non-interacting DC balance controls are
mounted on main PC board under electronics cover. A
mono-stereo switch is located next to the input jacks on
the rear panel.
Connectors: Input -'A inch phone jacks, output -color
coded binding posts, AC line -3-wire (grounded) male
connector on 5foot minimum cable.
Dimensions: 17 inches (43.18cm) long, 5!4 inches
(13.34cm) high, 8% inches (22.23cm) deep (from
mounting surface of front panel), 19 inches (48.26cm)
long with standard rack mounting brackets installed.

20KHz at 1watt into 16 ohms; ±ldB DC-60KHz, 180
watts RMS into 16 ohms.
Harmonic Distortion: Less than 0.001% from 20-400Hz
and increasing linearly to 0.05% at 20KHz at 160 watts
into 16 ohms.
LM. Distortion S.M.P.T.E. (60Hz-7KHz 4:1): Less than
0.05% from 0.01 watts to 0.25 watts and less than 0.01%
from 0.25 watts to 160 watts into 16 ohms, per channel.
Slewing rate: 12 volts per microsecond.
Damping Factor: Greater than 400, DC-400Hz into 16
ohms.
Output Impedance: Less than 30 milliohms in series with
less than 6microhenries.
Load Impedance: Rated for 16 ohm usage; safely drives
any load including completely reactive loads.
Voltage Gain: 41.2 ±2% for 160 watts into 16 ohms.
Input Sensitivity: 1.19 volts ±2% for 160 watts into 16

SECTION 6
ILLUSTRATED PARTS LIST
6.1 General Information
Section 6contains illustrations and parts lists for the D-
150A. This information should be used with the service,
repair and adjustment procedure in Section 7.
Most of the mechanical and structural type parts are
illustrated and indexed on exploded view drawings.
Electrical and electronic parts on these illustrations are
also identified by the circuit reference designation next to
the illustration. Both the index number and the reference
designation are included in the parts list in separate
columns. The reference designations correspond to those
shown in schematic diagrams in the Review Section.
Electrical and electronic parts located on printed circuit
boards are illustrated by schematic symbols on the trace
side and by component shape symbols on the component
side. Reference designations also appear on these
diagrams.
The quantity of each part used in each location is also
shown in the parts listing.
6.2 Standard and Special Parts
Many electrical and electronic parts used in the D-150A
are standard items stocked by and available from

that appear to be standard, are actually special. Apart
ordered from Crown will assure an acceptable
replacement. Structural items, covers and panels are
available from Crown only.
6.3 Ordering Parts
When ordering parts, be sure to give the amplifier model
and serial number and include the part description and
Crown Part Number (CPN) from the parts list. Price
quotes are available upon request.
