Front Panel Control Knob, Upon Power Up | Bel Canto Design DAC3.5VB

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 DAC3.5VB will perform its startup sequence followed by displaying the firmware revision.

After 2 seconds, Input Selection Mode will become active. The AES input will be selected by default and Soft Mute will be active. The volume will be set to 50.0 even if the fixed/variable button is in Fixed mode. The selected input is on the left of the display and the volume is on the right. The volume level will automatically ramp down and up during this selection process

Input Selection Mode:

Briefly press the control knob and the input on the left of the display will be highlighted. Rotate the control knob to scroll to the desired input. Inputs are indicated as: AES, SP1 (SPDIF1), SP2 (SPDIF2), OPT (TOSLINK), ST (High Speed ST Fiber) and ANLG (Analog Input).

Variable Output Mode:

The DAC3.5VB Variable Output operating mode, selected from the rear panel Fixed/Variable output switch, allows you to change volume level by rotating the knob or via the supplied remote control.

To adjust the volume, rotate the knob until the volume number on the right of the display is highlighted.

The volume down function (counter-clockwise rotation) is very rapid and allows quick changes in the volume level. Volume up (clockwise rotation) functions rapidly up to a displayed volume level of

65.0.Volume is adjustable from 0.0 to 100.0 by increments of 0.5.

Fixed Output Operating Mode:

Pressing the rear panel Fixed/Variable Output switch to the in position will set the DAC3.5VB in a fixed output operating mode. This mode is used when driving an analog preamp or integrated amplifier input. The volume control function is then provided by the associated preamplifier or integrated amplifier.

To use the Fixed Ouput mode set the ouput level to

100.0for a 2.75Vrms maximum level from the RCA outputs or 5.5Vrms level for the Balanced XLR outputs. If you want the outputs set for a lower level then set the volume control to a lower level. For example, for about 2 Vrms out from the balanced outputs set the volume control to 91.0. This will represent about a 2 Vrms output level on the balanced outputs. When the level is set then press the rear panel Fixed/Variable Output button. The front panel display will now show the selected input. Rotating the knob will scroll to different inputs and the Volume and Mute functions on the remote will not function.

Front Panel Digital Lock Indicator:

When no digital input signal is present on an input, LOS (Loss Of Signal) will appear on the display. If this occurs you need to check that the correct input is selected and then check that the digital source is connected, active and functioning correctly.
