M LO ST OP R E FF OF F C VO AB IC IN IN ET G ON / 2. 7 Master Level Controls Stereo Out and Mono Out Level Controls Use these controls to set the overall volume at the stereo and mono outputs. If your power amplifier has input level controls then you should set those controls between maximum and half to make sure that the power amp gets to maximum power well before the preamp does. Set the actual playing volume using the master level controls while using the individual channel volume controls only to balance the volume between the channels. 2. 8 The Graphic Equalizer The Graphic Equalizer, Bypass Switch , and LED Indicator The five band graphic EQ employs a bypass switch with the same memory recall feature as the reverb and master effects loop. The LED indicator at the front panel (and the one at the footswitch) always shows the current status of the graphic EQ. Each of the four channels will remember its graphic EQ status and switch the EQ on or off as each channel is selected. This allows you to assign the graphic EQ to some channels and not to others. The normal settings of the EQ sliders is the center (detent) position. When in doubt about the setting try returning the sliders toward the center position. 432 S BO OS CHANNEL SELECT INPUT T 10 2 10 2 Each slider acts as a volume control for a relatively narrow range of pitch. What matters is the differences in position. Boosting (or cutting) all bands the same amount would simply result in a volume adjustment. 2-6 B 10 Quad X-Amp Rear Panel Connections Section 3 Section 3 Rear Panel Connections 3. 0 The Rear Panel Layout The rear panel is organized with power switch and line cord connector at the far left.

Even though the Quad XAmp is a tube preamp, it does not require a standby switch because it does not use the high power tubes required for power amps. Rather, the Quad X-Amp uses 12AX7 tubes which run fairly cool and have a very long life. How to Set the Amp for 240VAC Power The fuse and the 115/230volt line switch are built into the AC line cord connector. To set the amp to operate from 230VAC (50 or 60 Hz) power first unplug the power cord and remove the fuse holder. Turn the fuse holder over and insert it so that it reads 230V right side up. The amp is now set to operate from 230 VAC. Fuse Values: 120 VAC : 1/2 Amp 240 VAC : 1/4 Amp ON POWER FUSE 120V 1. 5A 240V . 75A 5 3. 2 The FS-77 Footswitch Connector This D-9 connector is used to attach the FS-77 footswitch. Connect and disconnect the footswitch only when the power is turned off. [. . . ] Carvin will service the unit and supply all parts at no charge to the customer providing the unit is under warranty.
