UNPACKING UNPACKING INSTRUCTIONS 1. Open the box and remove the top layer items will now be visible: STUDIO 2 D/A Processor AC power cord Packet containing the Owner’s Card of foam. The following Reference NOTE: If any of these items are not included, authorized dealer immediately for assistance. 2. Carefully remove the STUDIO 2 from the protective plastic wrap from the Processor. and Warranty please box. contact your Remove the NOTE: Save all packing materials.
PLACEMENT PLACEMENT Before you install the STUDIO 2 into your system, we recommend that you follow these guidelines in choosing the location. This will facilitate a clean, trouble-free installation. 1. Although well shielded, the STUDIO2 should not be placed in close proximity to hum-sensitive components (i.e. preamps, turntables, tuners, etc.) that can create interference and induce hum. 2.
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. High quality AC line conditioners or filters can be utilized if they are grounded and meet or exceed the unit’s power supply rating of 150VA. CAUTION: Do not remove or bypass the ground pin on the end of the AC cord.
CONNECTIONS INPUT AND OUTPUT CONNECTIONS CAUTION: When making connections other, make sure the power amplifier is in the MUTEor STANDBYmode. to this component or any is OFF and the preamplifier 1. Connect the power cord to the back of the STUDIO2 and plug the unit into the wall AC receptacle. 2. Connect the STUDIO2 analog output to the line level input of your preamplifier. The STUDIO2 is equipped with two analog output configurations: Single-ended via RCAconnectors and balanced via XLR connectors.
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 RCAoutput is for the left channel output and the connector closest to the RCAright output is the right balanced output. Care should be taken to insure that the channel orientation between the Processor and the high level inputs of your preamplifier is maintained. 4.
CONNECTIONS 5. Once you have completed the necessary input and output connections, select the input of your choice. For each input selected, the corresponding LEDwill illuminate. When a powered digital input source and the Processor have linked, the SYNCLED will illuminate. ~, DIGITAL SOURCE TO D/A PROCESSOR INTERLINK CONSID ERATIONS Care should be taken in selecting the type of cable used to link the digital source to your Processor. We suggest the AT&Twidebandwidth fiber optic cable be used.
CONNECTIONS How to connect AT&Tcables: a. Remove the plastic cover from the outside of the AT&T transmitter (located on Transport) and receiver (located on Proeessor). b. Locate the slot on the top of the AT&Treceptacle. e. Locate the key on the top of the AT&Tcable. d. Removethe plastic cap from both ends of the fiber optic cable. e. Slide the cable connector into the AT&Treceptacle sliding into the designated slot. with the key f.
OPERATION INPUT SELECT SWITCHING The STUDIO2 has multiple digital inputs. Each input has its own input switch and direct path to the digital Processor. When an input is selected, the corresponding LED will illuminate. AT&T TOSH XLR COAX1 COAX 2/ST AT&Tfiber optic input Toshiba fiber optic input Balanced AES/EBU digital input Coaxial input Coaxial input or Optional-2nd AT&T ST input SYNC INDICATOR When the input signal locks with the Processor, the SYNC LED will illuminate.
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. To change the phase from 0 ° to 180 °, press the 180 DEG button. To change back to normal phase, press the 0 DEG button.
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. 2. Be sure that your preamplifier volume control completely to the OFF (lowest volume) position. is turned 3. Turn ON your components, remembering that the last component to be energized should be your amplifier.
’ " ’" OPERATION NOTE: While your STUDIO2 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. Discrete components are utilized in the analog output stage and the warm-up period allows them to reach thermal equilibrium. Your installation is now complete.
QUESTIONS Q. My CD player has both fiber one should I use? AND ANSWERS optic and coaxial outputs. Which A. Given a choice, we prefer the AT&Toptical link due to its ability to completely isolate the grounds between the digital source component and the Processor. This minimizes the possibility of ground loops in the digital components. The AT&Tformat also has the added benefit of substantially higher bandwidth than coax or the standard fiber optic interface.
QUESTIONS AND ANSWERS Q. Do I have to switch my CD and DAT? the Sampling Frequency A. No. Your STUDIO 2 automatically and does all necessary switching. Q. I am not getting be wrong? any sound through senses the when I go between input the Processor. frequency What could A. Most likely there has been a simple mistake in installation. Check all connections IN and OUTof the Processor. Is the digital source component powered? Check all power connections.
QUESTIONS AND ANSWERS Q. While listening to my STUDIO 2 I experience occasional periods of silence through my speakers. Is my Processor malfunctioning? A. Drop outs are caused by two primary reasons. First, drop outs can be caused by data corruption. Corruption in the data may be due to a poor input connection, damaged or dirty source material, or interconnects which do not have wide enough bandwidth.
