Front Panel Features

AC-ON ROTARY SWITCH: Turns AC power on in the “on” position.

GREEN ‘CAT EYES’: Indicate audio power output, fully closed eye at maximum power.

Rear Apron Features

INPUT: Signal input connection via either RCA or XLR shielded interconnect cables. Pin #1 is the shield, #2 positive phase signal on XLR connector.

INPUT SWITCH: Push in direction of the type of input to be utilized, RCA or XLR.

OUTPUT: The 5-way speaker binding posts provide the output to the speaker system. Red posts = positive connections, Black posts = negative connections.

AC: 3 conductor detachable power cord

AC POWER FUSE: Use only a 3 Amp, 250 V ‘slow blow’ fuse.

BIAS LED: These indicators will light when there is the proper bias voltage operating for the EL-84 current source tubes along with the proper DC grid bias voltage for the final output tubes. If these LED’s fail to light, discontinue use and place a call to the Cary Audio service advisor.

TRIODE/UL SWITCH: These switches change the operation of the Rocket 88 R between triode, class A, to Ultra-Linear, class A/B. These two switches maybe switched during operation. If one channel switch is in the opposite position from the other a channel imbalance will occur. There is 1 dB more gain in the Ultra-Linear position.

BIAS: This screw driver adjustment is used to set the proper DC bias current for the KT-88 output tubes. REMEMBER, THIS ADJUSTMENT MUST BE ADJUSTED WITH A METER READING DC mA CURRENT!

TUBE FUSE: This is a ‘fast blow’ _ amp fuse to protect the Rocket 88 R amplifier should an output tube fail.

CAUTION

USE OF ANY OTHER PROTECTION FUSE CAN DAMAGE UNIT

BIAS JACK: This _” two conductor jack is used to plug in the supplied meter cable. This is a shorting jack. In other words, when the plug is removed the circuit is automatically

CAD 808, Rocket 88 R specifications

Cary Audio Design has long been known for its high-end audio components, and the Rocket 88 R and CAD 808 amplifiers exemplify the brand’s commitment to excellence in audio performance. The Rocket 88 R is a tube amplifier that combines classic design with modern technologies, making it a popular choice among audiophiles who appreciate the warmth and character of tube sound. The CAD 808, on the other hand, is a solid-state powerhouse that brings to the table unparalleled clarity and power, providing a perfect counterpart to its tube-based sibling.

The Rocket 88 R is built around a unique dual mono configuration that allows each channel to operate independently, minimizing crosstalk and enhancing stereo imaging. This amp utilizes a pair of 6550 power tubes, delivering an impressive output of up to 100 watts per channel in push-pull mode. The result is a rich, harmonic sound that brings music to life, allowing listeners to experience their favorite tracks with an emotional depth that only tubes can offer. Additionally, the Rocket 88 R features Cary Audio’s proprietary Ultra-Linear and Triode switching modes, providing audiophiles with the flexibility to choose between a more powerful, dynamic sound or the intimate, lush qualities of triode operation.

The CAD 808 amplifies the experience even further with its advanced solid-state design. Featuring robust power supply and output stages, the CAD 808 is capable of delivering a staggering 200 watts per channel, ensuring that it can drive even the most demanding speakers with ease. Incorporating state-of-the-art technologies such as high-current output transistors and a fully discreet output stage, the CAD 808 minimizes distortion and maximizes input sensitivity, resulting in crystal-clear audio reproduction. Its low negative feedback design not only enhances the overall sound quality but also improves the amplifier's transient response, providing listeners with a more dynamic and engaging listening experience.

Both amplifiers boast beautifully crafted chassis with a blend of classic aesthetics and modern functionality. The Rocket 88 R is complemented by its glowing tubes and polished finishes, while the CAD 808 showcases a sleek, contemporary look with a user-friendly interface.

In conclusion, the Cary Audio Design Rocket 88 R and CAD 808 amplifiers stand out as exceptional choices for audio enthusiasts seeking both tube warmth and solid-state clarity. With their unique technologies and remarkable design characteristics, these amplifiers promise to elevate any audio system, ensuring an unforgettable listening experience.
