PRE to allow all cables sufficient room to bend without crimping or undue strain. Be sure to allow 2 to 3 inches of clearance above the PRE to allow heat dissi- Ventilation pation through air circulation.
Operating Voltage The PRE preamplifier is factory-set for 100V, 120V , 220V , or 240V AC mains operation at either 50 or 60Hz, according to the country for which the unit was manufactured. (230V/50Hz only in European Union countries, in compli- ance with CE regulations.) Make sure that the label on the rear panel of the...
PRE including relative volume levels, and is used in conjunction with the buttons which surround it. At all volumes above a relatively quiet back- ground level, and in all modes, the volume control enjoys a resolution of 0.5 dB.

By so doing, the PRE avoids sud- den, unexpected changes in volume. (See Using the PRE for information on changing the factory default mute setting.)

Audio Engineering Society. Refer to the operating manuals of your balanced-output line-level sources to verify that the pin assignments of their output connectors correspond to the PRE. If not, wire the cables so that the appropriate output pin connects to the equivalent input pin.
Page 14
If you use the single-ended outputs, connect them to the corresponding inputs of your power amplifier (or other device). Note that special fea- tures of the PRE enable it to be used optimally with a surround sound processor as one of its inputs. We do not recommend having a surround sound processor follow the PRE in the signal path.
IR peater input facilitates a wide range of installation options. If desired, the PRE may be placed inside a cabinet or outside the normal line-of-sight in the listening area, with the controlling IR signal being relayed to the PRE by any of a number of commercially-available IR repeaters.

AC MAINS FUSE AND AC POWER RECEPTACLE ac mains fuse is provided which disconnects the PRE from the wall outlet’s AC power under fault conditions. If this fuse should “blow” for any reason, replace it only with the same value fuse (0.5A/250V slo-blo 5x20mm).
Using the PRE Listening & Recording The input buttons of the PRE are used to select both the source that will be heard and the source that will be made available to any recording devices in the system. The button controls which of those selections is made.

PRESS AND HOLD THE INPUT BUTTON TO CONFIRM YOUR CHANGE Changes in the way the PRE normally operates require a conscious, de- liberate act on your part.
It is also important to remember that many of the buttons on the remote take on different functions, depending on the product selected using the Device Control Selectors. Buttons not directly described on the follow- ing two pages do not function with the PRE, but are available for use with other devices.

These buttons can be programmed to store Favorite Channels, Macro Commands, or to “relocate” functions from one mode to another. LIGHT BUTTON All buttons and the LCD on the PRE remote are back-lit for seven seconds when the button is pressed. The backlight is extended...

As with all buttons on the learning remote, this button can be “programmed over” if you wish. For example, you may decide to leave the PRE “on” all the time and use the standby button to turn another component on and off instead.
Learned Functions. NOTE: If you inadvertently overwrite one or more pre-programmed PRE com- mands in your PRE remote control, the PRE itself can send all of the necessary IR commands from its main display window, enabling you to teach the PRE remote both its pre-programmed commands and a few other, optional commands which you might find useful.

Device button, the new function will override any existing preprogrammed information on the Device button. Place the PRE remote and the original remote control to be learned from, on a flat surface. Line up the remote controls head-to-head, about two to three inches apart.
The learned functions on the selected buttons have now been erased. The pre-programmed functions for these buttons will now operate on the remote control. Erasing All Buttons in One Device Mode: Press the Device button for the mode to be erased.
NOTE: main device mode When the main Device mode is displayed in the LCD, the PRE remote will operate in a standard operating mode and all the buttons will operate in the preprogrammed, learned and punch-through features for that Device mode.

The PRE has two special modes of operation into which is may be placed in order to facilitate the “teaching” of remote control commands to its own (or any other) learning remote control.
This standby standby type of hard assignment command is especially helpful when you do not neces- sarily know the current status of the PRE, as might be the case in a multi-room home entertainment system (for example).
“L” (for “Learn”) when in this mode. The PRE will display a “0L” code when it has entered its teaching mode and is ready to help the remote control learn the commands that correspond to the PRE’s front panel but- tons.

This action will return you to the nor- mal “0L” front panel button level of programming. Y ou could, of course, also wait for the PRE to “time out” and return to this mode after about ten seconds.
Using Surround Sound Processors The PRE preamplifier incorporates a special surround sound processor mode allowing it to integrate the highest performance audio with surround sound— that is, dual-purpose music and movie systems. In order to better understand the value of this design, it is essential to understand a bit about the nature of a Dolby Pro Logic Surround ™...
Listening Room When you are ready to return to normal, two-channel stereo, simply select any other input on the PRE. Your video sources may then be connected to your surround sound processor while your music sources are connected to the PRE.
PRE while in “ssp” mode, the preamplifier cannot corrupt the careful calibration of the processor’s output levels. And since the video sources would be fed directly to the processor’s audio input(s) at a line level, input calibration cannot be disturbed by the preamplifier.
Care & Maintenance To remove dust from the cabinet of the PRE, use a feather duster. To remove dirt and fingerprints, we recommend isopropyl alcohol and a soft cloth. Moisten the cloth with the alcohol first and then lightly clean the surface of the PRE.
