INTRODUCTION Thank You for Choosing Parasound Your new Parasound Zphono XRM is an innovative and unique phono preamplifier. We are proud to offer you this exceptionally versatile audio component, confident that it will bring you many years of enjoyment and dependability. We appreciate you taking the time to read these instructions and thank you for selecting Parasound. For updates and corrections to this manual, we invite you to check our web site, www.parasound.com. Enjoy.
Unpacking & Placement Guidelines Unpacking Your Zphono XRM Carefully remove your Zphono XRM from its shipping carton and locate its AC power cord. While you are unpacking your Zphono XRM inspect it thoroughly for possible shipping damage and tell your Parasound dealer immediately if you find any. If possible, save and store the carton and the foam packing inserts, to protect the Zphono XRM if you have to move it or ship it.
Connecting & Adjusting your Zphono XRM Always disconnect your Zphono XRM’s AC cord and line stage preamp or integrated amplifier AC cords before making or changing the input or output connections. Inserting or removing turntable cables or output interconnects while the Zphono XRM and your integrated, line stage preamp or receiver are turned on can result in a blast of sound that can damage your loudspeakers. Make sure there is no strain or tension on any cables that could cause them to pull loose.
Cartridge Settings MC & MM Gain Options Before listening to the Zphono XRM you should select the appropriate gain for your cartridge. The most typical settings are 40 dB for MM and 60 dB for MC. This is a good place to start but you may want to experiment to see what sounds best in your system. We suggest turning off the Zphono XRM before making gain changes to prevent an audible “pop” noise. MC Gain Options: 50 dB For high output moving coil cartridges.
AC Power Connection AC Power Inlet & Power Cord A high quality IEC-type power cord is supplied with your Zphono XRM. Please connect it directly to an AC wall outlet or power line conditioner that is always “live.” If possible, plug your Zphono XRM into the same AC wall outlet or line conditioner that your preamplifier or integrated amp is plugged into. If a different AC outlet is used for the Zphono XRM the ground potential may be higher or lower between the AC outlets, resulting in audible hum.
Frequently Asked Questions Why is there no sound from the speakers? - Ensure the front panel Input Switch is set to the correct option. - Check that the power LED on the front panel is illuminated indicating the unit is powered on. - Check that input and output cables are secure at both ends. I can hear a background hum or hiss from the speakers - Try a lower gain setting. - Make sure that you have attached your turntable’s ground wire to the ground terminal on the back panel of the Zphono XRM.
