WE DON’T RECOMMEND YOU LET YOUR CATS SLEEP ON FREYA, but we’re not gonna CoMMent further. FREYA WELCOME TO FREYA Freya is a no-compromise, ultra-high-end balanced preamp cleverly disguised by a low price tag. You won’t find any volume-control chips or other shortcuts in Freya—just uber-quality techniques like a relay-switched stepped attenuator and all-triode gain stage—you know, just like what’s used in the most expensive audio gear. ONE Freya ONE Power cord ZERO Stick-on feet (they’re pressed in) IN THE BOX The following is required by the roughly 9,542 government agencies and regulations we have to comply with. If you have some common sense, they should seem pretty straightforward. In any case, read these instructions before proceeding farther, follow all instructions, and heed all warnings. Or else! 1. If you don’t know how to install audio devices, get a qualified professional to help. 2. Never use this device near water, and clean only with a dry cloth. 3. Assure adequate ventilation, do not block any ventilation openings, or place near heat sources. 4. Use only the supplied power cord or suitable replacement. Route cords away from traffic areas and protect them from being pinched. Unplug the cord from the outlet if the apparatus is unused for a long period of time. 5. To prevent electric shock, do not use the plug with an extension cord, receptacle, or outlet unless blades can be fully inserted. 6. Refer all servicing to qualified service personnel. Service is required when the device has been damaged, including cord or plug damage, liquid has been spilled or objects have fallen into the device, the device has been exposed to rain or moisture, does not operate normally, or has been dropped. SAFETY INSTRUCTIONS WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS DEVICE TO RAIN OR MOISTURE. Application for Council Directives 72/23/EEC Conformity declared for EN60065, EN50082-1 GETTING STARTED CAUTION! Dangerous voltages inside! 1. Before plugging in the preamp, insert the tubes. Carefully align the key in the tube base to the notch in the tube socket for each tube. It doesn’t matter which tube goes where—all tubes in Freya are the same exact type (6SN7, or, for Russian NOS tubes, 6N8S). 2. Ensure tubes are well-seated. Push down firmly until the tube is seated on the tube socket. This may take a fair amount of force. 3. Plug it in and turn it on. The tube will glow after a few seconds, and the microprocessor will connect the output after about 30 seconds. 4. Connect your sources. Connect up to 5 sources to Freya’s balanced and single-ended inputs. 5. Connect the output. Connect the output of Freya to your amp or amps using XLR or RCA cables 6. Ensure the volume is turned down if you’re using Freya for the first time. You don’t want any big surprises! 7. Power it up, turn it up, and enjoy your music! TUBES Replacing Tubes Freya accommodates any 6SN7, 6N8S, or 5692 tube type. 6SL7, 6N9S, and equivalent types also work, but will have higher distortion and higher output impedance. If you’re curious, the right tubes are for the differential voltage gain stage. The left tubes are for the cathode follower output stage. All tubes are of the same type on Freya. To replace or swap tubes: 1. Turn off and unplug the preamp. Wait a while for the tube to cool. Seriously, these suckers are pretty hot. 2. Carefully extract the tube by gently rocking it back and forth and pulling upwards. 3. Carefully insert the replacement tube. Align the key to the notch and press down firmly until the tube is seated. 4. Plug the preamp back in and turn it on. NOTCH
