Volume Control (Vol); Telephone Tx (Dmp 128 C P And Dmp 128 C P At Only) - Extron electronics DMP 128 User Manual

Volume Control (VOL)

Each output channel volume block provides a mono long-throw fader
and a volume setting readout (in dB) below the fader. Volume level
adjusts with the slider or by entering the desired level directly into the
volume setting readout in 0.1 dB increments.
Click the fader handle or click within the fader area to bring focus to
the fader. The input signal level is adjusted using any of the following
methods:
• Click and hold the fader handle and drag it to desired level in
1.0 dB steps.
• Click or <tab> to the fader handle and use the <up> and <down>
arrow keys to change the desired level in 1 dB steps. <Page Up>
(increase) and <Page Down> (decrease) the level in 5 dB steps.
• Click in or tab to the level readout field. Type a new value and
press <Enter> or <Tab> to another area.
The default setting is unmuted, at 0 dB attenuation. A peak meter
displays the real-time audio level from -60 to 0 dBFS.
Click OK to accept settings and close the dialog box. Click Cancel to ignore changes and
close the dialog box.
The output volume control provides level control for each output. The output control is a trim
control adjustable from -100.0 to 0 dB. The default setting is unity gain (0.0 dB).
The Polarity button, allows the polarity of the wires connected to the audio connectors
(+/tip and -/ring) to be flipped in order to easily correct for miswired connectors.
The Mute button silences the post-meter audio output. When the audio output is muted,
the mute button lights red, and red indicators in the block turn on.
If the output has been grouped with other inputs or outputs, the group number is indicated
on the right side of this button (see

The DMP 128 provides a telephone interface with separate input and output signal
processing paths. The telephone output (Tx) is identical to the other output processing
paths. All signals routed to the Telephone Tx are also available on output 8.
