McIntosh C48 Preamplifier

Excellent condition C48, ships in manufacture packaging with manual and remote.  Remote is the soft touch remote which over time gets a little sticky to the touch, same with this one’s remote.  

 C48 is the ultimate McIntosh preamplifier

value, bridging the two worlds of

conventional analog stereo source with

the latest digital music sources.

Offers control of 8 analog sources

including phono cartridges, plus 4

additional programmable digital inputs

and one dedicated USB computer

music input.

Unique features include home theater

pass through, amplifier meter light control

and RS232 software upgradability.

Five band tone controls that may be

actively programmed by input, moving

coil and moving magnet phono sections

are fully adjustable from the remote

control volume control.

Frequency Response:

+0, -0.5dB from 20Hz to 20kHz

+0, -3.0dB from 15Hz to 100kHz

Total Harmonic Distortion:

0.002% maximum from 20Hz to 20kHz

Rated Output Voltage:

Unbalanced Outputs 1 & 2: 2.5Vrms

Balanced Outputs 1 & 2: 5 Vrms

Maximum Voltage Output:

Unbalanced Outputs 1 & 2: 8 Vrms

Overall Dimensions (W x H x D):

17-1/2” (44.45cm) x 6” (15.24cm) including

feet x 18” (45.72cm) including the front panel,

knobs and cables

Weight:

26.5 lbs (12kg) net,

41 lbs (18.6kg) in shipping carton

Inverted Double-Chassis Design:

All analog signals and amplification are nestled

into the top section, protected from any noise

generated by the power supply or digital

circuits that are contained in the bottom

section. This achieves the performance of a

dual-box component with the convenience of a

single-chassis component and provides for

ultra-short cabling between sections.

Silent Electromagnetic Switching:

Signal routing is accomplished through

digital controlled electromagnetic switching

devices. Precision switch contact, isolated

from environmental contamination inside

inert gas-filled tubes, provide the most

reliable, quietest and lowest distortion

switching possible.

VRV (Variable Rate Volume)

Digital Controlled Attenuator:

The output attenuator controls volume over

214 steps of 0.5dB each with accuracy within

0.1dB. The volume vs. rotation rate varies as

preamplifier gain varies and attenuation

changes occur at the zero crossings of the

audio signal to prevent audible artifacts

during adjustment.
