Setup & Placement

The e.One Pre5 can be placed in many locations without compromise. We do not recommend placing weights or other objects directly on this product.

This may scratch or mar the chassis finish. Do not use harsh chemicals or abrasives when cleaning the outside. Use a clean microfiber cloth to remove fingerprints from the chassis.

Single Ended RCA and Balanced XLR connectors are available. XLR connectors follow the standard AES pin configuration:

• Pin 1 Ground
• Pin 2 Signal +
• Pin 3 Signal –

We recommend placing the e.One Pre5 in an easily accessible location near your source components.

Rear Panel Connections

IMPORTANT: Read the full manual before connecting to AC power

1. IEC Inlet. Region specific voltage is internally set.
2. Balanced Line Outputs: 5Vrms Maximum level
3. Mains Power Switch connects AC input to the power board when set to the I position.
4. RCA Line Outputs: 5Vrms Maximum Level
5. RCA Line Inputs 1-/i: RCA analog input signals up to 2.5Vrms
6. Balanced Inputs: XLR analog inputs up to 5Vrms

When all connections to and from the unit have been made then double check everything before plugging the Pre5 into the power source. After turning on, the Pre5 will go through its display check and show the software revision number.
The unit will be in Mute with the BAL input selected. The volume will be set to 50.0.

Single Knob Control Functions & Display

Front Panel Control Knob:
The control knob is a continuously rotating control with a push-switch function. Always push the button with your finger in the direct center of the knob. Pushing the knob will switch between selectable values on the display. Rotating the control left or right will adjust the selected value.

Upon Power Up:
When switched on, the Pre5 will perform its startup sequence followed by displaying the firmware revision.
After 2 seconds, Input Selection Mode will become active. The Bal (Balanced XLR) input will be selected and Mute will be active. The volume will be set to 50.0.

Volume Control:
The Pre5 allows you to change volume level by rotating the knob. The volume down function (counterclockwise rotation) is verv rapid and allows quick changes in the volume level.

Input Selection Mode:
Pressing the control knob in briefly will toggle into the input selection mode. The selected input will be displayed for 5 seconds. During this time you can rotate the control knob to scroll to the desired input. Pressing the knob again will select the indicated input. The volume level will automatically ramp down and up during this selection process. If the control knob is not pressed for 3 seconds, the indicated input will automatically be selected and the Pre5 will return to the default volume control mode. Inputs are indicated as: Bal, Lint, Lin2, Lin3, Lin4.

Hard Mute Using Control Knob
To Hard Mute the Pre5 from the front panel, press and hold the Control Knob for 2 — 3 seconds. To un-mute, rotate the Control Knob clockwise or press either the Mute or VoI+ button on the remote control.

e.One Remote Control

PRE mode button sets the control for Pre mode for controlling the Pre5, DAC mode for controlling a DAC2.7 or older Bel Canto DAC.
Display: Toggles through several display options:

1. Normal mode
2. Firmware Revision Display
3. Product Name
4. Display Off: Turns off the display. Display comes on for several seconds whenever a status change is detected

Soft to Hard Mute to Un-muted.
V0L+ Ramp up symbol: Increases the volume setting.
Used in Program mode to navigate up.
VOL- Ramp down symbol: Decreases the volume setting. Used in Program mode to navigate down.

Right Arrow: This will toggle the input selection up in number and wrap around to the lowest number. Note that the first press of this control will show the active input selection. Used in Program mode to navigate right.

Left Arrow: This will toggle the input selection down in number and wrap around to the highest number. Note that the first press of this control will show the active input selection. Used in Program mode to navigate left.

Program: Press to enter programming mode. Hold for 2-3 seconds to exit programming mode and save the program settings.

lf the Pre5 does not respond to the remote commands press the PRE button to toggle the mode.

Tips for Operation

Power Up
We recommend leaving the Pre5 powered on at all times as it benefits the overall sound qualitv and draws little power.
If your system will not be used for an extended period of time, such as two weeks, or if there is an imminent electrical storm, we recommend shutting off your system. NOTE: If the Pre5 does not receive any sort of user input for 2 hours, the display will go into a screen saver mode.

Home Theater Bypass
The inputs can be placed into Home Theater Bypass by programming a specific input for HTB mode. HTB will be shown on the display instead of the volume setting when an input is in this mode.

What to do if there is hum or ground noise
The design of the Pre5 greatly reduces the chance for ground loop induced hum and noise. Connect all power cables of the audio system to a common outlet box or power conditioner unit. Having the audio system components share a common ground will greatly reduce the possibility for ground current noise being introduced into the audio signal path.

Programming Modes

There are several programming options with the Pre5. You program the unit by either pressing and holding the knob for several seconds and using short presses and scrolling the knob to navigate and set the programming or by using the Program button on the remote and navigating and scrolling settings using the left/right/up/down buttons. Save the program settings by either pressing and holding the knob or pressing and holding the Program button for several seconds.

1. MAX Volume:100 -default is 1 00, this can be reduced to prevent excessive volume levels.
2. EDIT Input -this is used to change naming and settings on each input, an example is shown below:
3. BAL ON BAL -the first field shows the input to program, the center field can be set to ON, HTB (Home Theater Bypass) or OFF. HTB sets the input to a unity gin setting of BE for use with an external surround processor where volume is controlled from the processor, OFF will prevent the input from being selected when scrolling inputs.
4. BALANCE -default is 0, this allows the right > or left < balance to be set up to 6dB in 1 2 0.5dB steps
   • Reset PGM: NO/YES — will reset the programming to factory defaults if YES is selected

Remember to press and hold either the Program button on the remote or the knob to save and set the programming when you have finished your settings.
