D Voltage Changeover and Optional Transformers This section describes voltage changeover and installation of optional transformers.
Lexicon 480L Owner's Manual Voltage Changeover Voltage changeover is a fast and easy process: 1. Remove the power cable from the 480L. 2. Insert a small flat-bladed screwdriver or an IC puller into the slot next to the fuseholder cartridge, which is located just to the right of the power connector. Pry the cartridge out so that it drops out of the chassis. Set the fuseholder cartridge aside. 3. The voltage changeover board is mounted vertically in a small compartment which is normally covered by the fuseholder cartridge (which you removed in step 2). Remove the board with a pair of needle-nosed pliers or tweezers. 4. The four sides of the board are marked with the four voltages at which the 480L can be operated (100, 120, 200, 240). Slide the voltage changeover pin around until it fits in the notch opposite the side marked with the operating voltage you require. 5. With the pin facing out, replace the board in the chassis. Press it until it snaps into place or fits firmly in its socket. 6. The fuseholder cartridge is supplied with two sets of fuses—a single 3 A, 3AG Slo-blo fuse for 100/120 V, and two 1.5 A 20-mm Slo-blo fuses for 220/240 V. To change the fuses over to 220/240 V, remove the small Phillips-head screw on the cartridge, and turn over the board. Reinstall the screw. The European 20-mm fuses should now be visible. Reverse the process to change from 220/240 V to 100/ 120 V operation. 7. Reinstall the fuseholder cartridge. Check the pin indicator to verify that you selected the correct voltage. If none of the holes in the fuseholder line up with the pin on the voltage changeover board, you installed the board upside down. Reinstall it correctly and try the fuseholder again. Installing the Optional Transformers Some applications require that the 480L operate under adverse electrical conditions. In these situations, it may be beneficial to transformer-couple the 480L's audio inputs and outputs. The 480L allows easy installation of audio transformers inside the unit. Please note that transformers are not available from Lexicon. They can be purchased directly from their manufacturer or a pro audio dealer. If you choose to install transformers, follow these instructions carefully. For the 480L inputs, we recommend Jensen JE-11P-1 transformers. 1. On the main circuit board (component side) of the 480L, cut the etch between E4 and E7, E5 and E8, E10 and E13, E11 and E14. 2. Install a 510 pF 2.5% polypropylene capacitor at C143. 3. Install a 510 pF 2.5% polypropylene capacitor at C183. 4. Install a 15 kilohm, 1% resistor at R152. 5. Install a 15 kilohm, 1% resistor at R187. 6. Connect a Jensen JE-11P-1 transformer as follows for the left channel: 480L E3 E4 E5 E6 E7 E8 Transformer White Brown Red Black Orange Yellow 7. Connect a Jensen JE-11P-1 transformer as follows for the right channel: 8. This completes the voltage changeover. 480L E9 E10 E11 E12 E13 E14 Transformer White Brown Red Black Orange Yellow D-2
