DVS 510 Series • Operation 40
Volume Control
Rotating the
VOLUME
knob on the front panel increases and decreases the audio volume in
up to 100 steps.
NOTE: This knob is speed sensitive, that is, you can turn the knob quickly to make
coarse adjustments or slowly to make fine adjustments.
The table below shows some examples of the amount of rotation needed to achieve volume
levels.
Volume Knob Rotations Volume Level Steps (0–100)
½ 25
1 50
1½ 75
2 100
When this knob is turned, the LCD window displays a bar graph representation of the
volume level for 0.5 seconds before returning to the previous menu. In addition, the step
number is displayed at the top of the LCD screen.
Volume 22

Volume adjustment can be made from the front panel at any time during scaler operation.
Volume LEDs
To the right of the VOLUME knob are three LEDs that indicate the volume level (see figure 24
on the next page):
• Max (red) — Lights steadily when the volume level is between 80% and 99%. When
the volume is at 100% (maximum), this LED flashes.
• Mid (green) — Lights steadily when the volume level is above 49%.
• Min (green) — Lights steadily when the volume level is above 1%. When the volume is
at 0 (minimum), this LED blinks. It also blinks when the audio is muted by SIS command
(see the
Audio Mute commands on page 64) or by the IR remote control (see Using
the Optional IR 904 Remote Control on page 44).
NOTES:
• When the volume is muted, all the Volume LEDs go dark except Min, which blinks.
• When an incremental Volume LED lights, the LEDs below it remain lit. For example,
when the Max LED lights, the Mid and Min LEDS are also lit.
