••
• Dual Chassis with Dual Mono Design
The Dual Chassis design completely separates all power
supply, microprocessor and control circuits from the pure
audio circuits for total noise isolation. To further aid in
channel isolation the circuitry for both channels is totally
separate, physically isolated and shielded. The C1000 incor-
porates two identical power supplies one for each channel,
to help assure total channel isolation.
••
••
• Balanced and Unbalanced Inputs/Outputs
Four balanced high level inputs and three balanced main
outputs are provided. Four high level unbalanced inputs,
two unbalanced outputs as well as listen and record proces-
sor loops are included.
••
••
• Moving Coil and Moving Magnet Phono Inputs
The C1000 contains two different shielded precision Phono
Preamplifier Circuits. One is designed for low output Mov-
ing Coil Phono Cartridges and has selectable resistance
loading. The second Phono Preamplifier is for Moving
Magnet Cartridges and has selectable capacitive loading.
Both circuits use the latest designs to provide the lowest
possible noise and distortion. The RIAA Correction Equal-
ization Circuitry utilizies 0.5% tolerance resistors and 1%
capacitors for an extremely flat frequency response.
••
••
• Input Level Trim Adjustment
All the C1000 Inputs can be matched in level, so there are
no abrupt changes in volume levels between the different
inputs.
••
••
• Precision Tracking Variable Rate Volume Control
Volume levels are controlled by a Multi-Stage Precision
Digitally Controlled Attenuator System with an Optical En-
coder Rotary Control. This helps to assure a tracking accu-
racy between channels of 0.1dB, while providing 214 indi-
vidual 0.5dB steps of change in the volume level and all of
this with no noise as the volume level is changed.
••
••
• Balance Control
The Balance Control Circuitry allows for precise and re-
peatable change in channel balance in 1dB steps.
••
••
• Alphanumeric Fluorescent Display
The Multifunction Front Panel Display indicates the Listen
and Record Source Selection, with Volume indicated in dB
or percentage and Balance Levels in dB. Setup Mode Selec-
tions and Adjustments are also displayed.

• Precision Parts
All resistors are precision metal film type. Low dielectric
absorption film capacitors are used in all critical circuit lo-
cations.

Passthru Mode
The Automatic Passthru Mode allows the C1000 to become
part of a Multichannel Sound System for DVD-Audio,
SACD and Home Theater Movies.
••
••
• Remote Controls
The two Remote Controls included with the C1000 allow
remote operation of the Preamplifier along with controlling
various other McIntosh Source Components and Proces-
sors.
••
••
• Optional External Sensor Input
There are provisions for connecting external sensors, which
allow for enjoying your McIntosh System from other
room(s) in your home via the remote control.
••
••
• Power Control Output
A Power Control connection for convenient turn-on of
McIntosh Source Components, McIntosh Power Amplifiers
and accessories is included.
••
••
• Glass Front Panel with Fiber Optic Illumination
The famous McIntosh Illuminated Glass Front Panel, with
1/2 inch thick sections, has a three dimensional look helping
to ensure the pristine beauty of the C1000 will be retained
for many years.The Illumination of the Front Panel is ac-
complished by the combination of custom designed Fiber
Optic Light Diffusers and Light Emitting Diodes (LEDs).
This provides even Front Panel Illumination, together with
the extra long life LEDs.
••
••
• Machined Top and Side Panels
The Top and Sides of the C1000 are machined from thick
aluminum panels with a smooth black anodized finish. In
the recessed area of the Top Panel is a screened glass panel
with a block diagram of the C1000 Circuitry.
••
••
• Special Power Supply
Fully regulated Power Supplies, one for each channel, uti-
lize special R-Core Power Transformers helping to ensure
stable noise free operation even though the power line var-
ies.
