NOTE : Before installing your new power amplifier, please read this manual carefully as it will inform you of the specifications, proper installation procedures and operation procedures. Also included in this manual are guidelines on how to properly service and care for your new Rocket 88 R .
Dear Audiophile Friend: I would like to take this opportunity to personally thank you for purchasing a Cary Audio Design Rocket 88 R stereo power amplifier. I have spent many, many hours designing and voicing this latest iteration of our very popular Rocket 88.
THEORY OF OPERATION For the technically minded, a review of the circuit is in order. Your new Rocket 88 R operates in push pull triode Class A mode and in class A/B ultra-linear mode. The output stage KT -88 tubes are biased with a negative fixed bias voltage for low distortion and maximum output capabilities.
even higher overall power output levels to try to solve the clipping problem. In reality, we believe the most critical aspect is how fast a recovery an amplifier can achieve after overload. With the incredible dynamics range of live and recorded music, even 2,000 watts of power is potentially not enough.
DIMENSIONS: 10”W x 18”D x 6”H (25.4 cm x 45.7 cm x 15.2 cm) WEIGHT: 45 Lb.. (20.4 kg) CIRCUIT TYPE: Push-Pull Triode Class A, Ultra-linear Class A/B POWER OUTPUT: 30 Watts Triode, 60 Watts Ultra-linear INPUT SENSITIVITY: 1.
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.
connected. You may plug in the test plug while the unit is playing. You may hear a slight click in the loudspeakers when inserting or removing the plug. This is normal. SPEAKER : These switches change the 4 and 8 ohm output taps from the output transformer to the speaker posts on the rear of the amplifier.
Amplifier Placement and Set Up In general, the location of your new Rocket 88 R amplifier is not critical. The best placement in your system is near the speaker system with short lengths of speaker cables. Certain precautions must be taken to ensure optimum performance.
illuminated. Should you not observe the above conditions, turn off the amplifier and check the power cord and AC socket . Triode/Ultra-Linear Switch On the top of the chassis behind the KT -88 output tubes is located a chrome handle switch. With the handle pushed to the rear of the amplifier the mode of operation is ultra-linear.
Break In Period The tubes, capacitors and output transformers take approximately 100 hours of music playing to fully settle in for peak performance. The Rocket 88 R will sound good fresh out of the box. However, after the first couple of hours you will notice increased depth and tighter bass.
WARNINGS! MAKE NO ATTEMPT TO PUT THE ROCKET 88 R INTO SERVICE OUTSIDE OF THE CABINET. CONTACT WITH THE HIGH VOLTAGES FOUND INSIDE THE UNIT CHASSIS CAN BE FATAL! COMPLETELY REMOVE THE AC POWER PLUG FRO.
