INTERCONNECT CABLES

The interconnect cables from the output jacks of the SLP-308 to the input jacks on the power amplifier can be any convenient length your set up requires. The choice of a high quality interconnect cable is important. Your Authorized Cary Audio Design Dealer will have proper interconnect cables in stock for this purpose. The low output impedance of the SLP-308 will run long interconnect wire runs, as long as 30-40 ft., without a problem. We suggest wires with good shielding if you live near transmitter towers for TV or radio stations.

OPERATION

Your new SLP-308 preamplifier is ready for operation after the various interconnect cables have been installed and the unit is plugged into the household AC mains 120 Volt AC wall socket. The SLP-308 is provided with functional, useful front panel controls with an attractive and logical layout.

POWER SWITCH

The toggle power switch is located at the left side on the SLP-308 preamplifier front panel. The switch operates in the following manner:

OFF

(Down position) Removes all AC voltages from the SLP-308 power supply.

ON

(Up position) Turns on the AC voltage to the power transformer primary

 

on. The power transformer has a 200% duty cycle. In simple terms,

 

the transformer is capable of operating two (2) SLP-308 preamplifiers

 

continuously 24 hours a day. We recommend that the AC power

 

switch be left in the ON position at all times. The SLP-308 sounds

 

much better after 100 hour burn in and when warmed up for _ hour.

Operate LED This blue LED will light after the SLP-308 is warmed up and biased properly.

VOLUME CONTROL

The gain of both left and right channels is controlled simultaneously by this control. The control potentiometer is of such high quality that the tracking error is less than 0.5 dB from 0 to -60 dB. The program source remains in balance over the entire range of this control. The taper rate of the volume control has been chosen to provide a rapid increase in gain over the first half of rotation and slower gain increase above 12:00 position. The volume pot is controlling the input signal to the first grids of the 12AU7 tubes. The volume control has a DC motor attached for remote operation. The blue LED in the volume knob is confirmation at a glance as to the overall level when you are too far away to read the output level meters.

SLP-308 specifications

Cary Audio Design has long been a name synonymous with high-quality audio equipment, and the SLP-308 is a prime example of their commitment to excellence. This line-stage preamplifier is designed to offer superior sound reproduction, making it a favorite among audiophiles and music enthusiasts.

At the heart of the SLP-308 is its all-tube design, which delivers a warm, organic sound that digital amplification often struggles to replicate. The preamp utilizes high-quality vacuum tubes known for their rich harmonic content and natural tonal balance. This results in a listening experience that feels both engaging and lifelike, allowing users to connect more deeply with their music.

One of the standout features of the SLP-308 is its fully balanced circuitry. This design minimizes noise and distortion, ensuring a clean signal path from your source component to the amplifier. The balanced topology not only improves the overall performance but also increases the versatility of the preamp, enabling seamless integration into a variety of audio systems.

The SLP-308 is equipped with both balanced XLR and single-ended RCA inputs and outputs, accommodating a wide range of audio components. This flexibility is essential for audiophiles who wish to optimize their systems with different sources and amplifiers.

In addition to its stellar sonic capabilities, the Cary SLP-308 boasts a user-friendly interface. The front panel features an easy-to-read display and intuitive controls, making it simple to navigate input selection and volume adjustments. The remote control functionality enhances convenience, allowing users to operate the preamp from their listening position.

Another important aspect of the SLP-308 is its power supply. The preamp features an external power supply, which not only isolates sensitive audio circuitry from noise generated by AC power but also enhances performance and reliability. This thoughtful engineering approach is a testament to Cary Audio's attention to detail in crafting high-fidelity components.

With its robust build quality and exquisite aesthetics, the Cary SLP-308 is designed to perform reliably for years. Its classic look, combined with modern technology, ensures that it will fit seamlessly into any high-end audio setup while providing the auditory pleasure that Cary Audio is known for.

In conclusion, the Cary Audio Design SLP-308 line-stage preamplifier stands out as an exceptional choice for those seeking a premium audio experience. Its all-tube design, balanced circuitry, flexibility, ease of use, and superior build quality make it a cornerstone product in any serious audiophile's collection.
