AC POWER AC POWER CONSIDERATIONS NOTE: While the STUDIO 2 has superb regulation and does not require a dedicated AC circuit, we strongly advise against any connections through extension cords or multiple AC adaptors. High quality 15 amp grounded AC strips are acceptable.
CONNECTIONS INPUT AND OUTPUT CONNECTIONS CAUTION: When making connections to this component or any other, make sure the power amplifier is OFF and the preamplifier is in the MUTE or STANDBY mode. 1. Connect the power cord to the back of the STUDIO 2 and plug the unit into the wall AC receptacle.
CONNECTIONS 3. The Left and Right channel RCA outputs are labeled on the back panel. The balanced outputs are not labeled. The balanced connector closest to the Left RCA output is for the left channel output and the connector closest to the RCA right output is the right balanced output.
CONNECTIONS 5. Once you have completed the necessary input and output connections, select the input of your choice. For each input selected, the corresponding LED will illuminate. When a powered digital input source and the Processor have linked, the SYNC LED will illuminate.
CONNECTIONS How to connect AT&T cables: a. Remove the plastic cover from the outside of the AT&T transmitter (located on Transport) and receiver (located on Pro- eessor). b. Locate the slot on the top of the AT&T receptacle. e. Locate the key on the top of the AT&T cable.
OPERATION INPUT SELECT SWITCHING The STUDIO 2 has multiple digital inputs. Each input has its own input switch and direct path to the digital Processor.
OPERATION 0 ° and 180 ° PHASE SWITCHING The absolute output phase of the STUDIO 2 can be changed. In some recordings the master tape was recorded out of phase, creating unusually poor sounding recordings. The STUDIO 2 can shift the absolute output phase 180 ° to correct for this anomaly.
OPERATION OPERATING INSTRUCTIONS 1. Select an input with the Input switch. Notice the Signal LED will illuminate when the digital source is turned on and has linked with the Processor. Once this link is complete, the Processor is ready to pass a signal.
OPERATION ’ " ’" NOTE: While your STUDIO 2 will perform beautifully from the moment you turn it on, it requires a minimum warm-up period of 8 hours before it begins to show its strongest sonic qualities. It will continue to improve over time.
QUESTIONS AND ANSWERS Q. My CD player has both fiber optic and coaxial outputs. Which one should I use? A. Given a choice, we prefer the AT&T optical link due to its ability to completely isolate the grounds between the digital source component and the Processor.
QUESTIONS AND ANSWERS Q. Do I have to switch the Sampling Frequency when I go between my CD and DAT? A. No. Your STUDIO 2 automatically senses the input frequency and does all necessary switching. Q. I am not getting any sound through the Processor. What could be wrong? A.
QUESTIONS AND ANSWERS Q. While listening to my STUDIO 2 I experience occasional periods of silence through my speakers. Is my Processor malfunc- tioning? A. Drop outs are caused by two primary reasons. First, drop outs can be caused by data corruption.
