Thank You By purchasing the Zen Triode CSP preamplifier you have illustrated a desire to rise past the normal hi-end hype and own a truly exceptional piece. It is a product based on the old school way of doing things when it was fashionable to push quality to an art form. Your amplifier was hand-built by the very best artisans who have perfected the craft through the experience of building well over one thousand amplifiers, each one at a time.
Introduction and Performance Features Important Information Fuse location / Information 1 The fuse is integrated into the IEC power cord connector at the back of the CSP2. 2 3 4 Caution: To prevent electrical shock make sure that the AC POWER CORD IS NOT CONNECTED TO THE CSP2 when inserting or removing Vacuum Tubes, as there are hazardous voltages present at the pins of the Tube Sockets. When Vacuum Tubes are installed or removed make sure to seat them properly in the tube sockets.
OUTPUT LEVEL The CSP2 is designed with an adjustable line output level that will set the voltage for both the stereo and mono output jacks. There are two thumb pots located just off the rear corners of the power transformer that are used to adjust the output level for each channel independently. These pots have been pre-adjusted at the factory and marked so that you can easily restore your CSP2 to the factory calibration. Factory calibration of the output level is set to 4.00 Volts at 1000 Hz with a 2.
INPUT TUBE INFORMATION WHERE EVERYTHING GOES The CSP2 is designed to use your choice of three different input (or signal) tubes. Below is a simplified top view of the chassis showing the tube locations, jack and switch locations. 6N1P The sound is typically warm with good balance. 6DJ8 (a popular low noise tube both available in current production by numerous manufacturers and in N.O.S.) The sound is more airy and detailed, less bass.
INTRODUCTION You now own one of the best SET headphone/ preamplifiers in the world! It has many unique features that set it apart from the rest. It’s point-to-point construction, lack of circuit boards, and direct coupled signal path means nothing sold today is more transparent or honest. Of course almost everything sold today claims to be sonically transparent and absolutely accurate, but when compared side by side to the Zen Triode CSP2 it usually isn’t.
DIMENSIONS The CSP2 amplifier is 7.25 inches wide by 14.75 inches deep with a height of 6.5 inches. With the jacks vertically mounted at the rear of the amplifier, it is possible to push the amp all the way to the rear of a shelf. However, we recommend keeping a 2 inch spacing on all sides and at least 6 to 10 inches of space above the amplifier. Avoid closed cabinets. The better the ventilation around your amplifier the cooler it will run.
HEADPHONE USE HOW TO OPERATE The CSP2 is a world class OTL headphone amplifier. It will operate most headphones between 30 ~ 600 ohms. It uses a standard 1/4 inch stereo jack that is directly tied to the output and controlled by the master volume control. After finding an appropriate place for the amplifier you can install the tubes and connect the cables. Do not hook up the input cables at this time. Install the power cord and plug it into a grounded receptacle and turn the unit on.
