Switching Between Mic- and Line-Level Input (Analog Only)
To toggle a channel between Mic-level and Line-level, perform the following, on the Input Configure page
(Analog Inputs selected) {p.87}:
1. Press the Mic/Line Level button on the page. The LED on it flashes green indicating it’s active.
2. Press one of the Analog (#) buttons for the channel you want to change. It displays the current mic / line level
setting.
3. Repeat #2 for each additional channel you want to change.
4. Once the last channel has been changed, press the Mic/Line Level button again. The LED stops flashing.
Enabling the High Pass Filter (Analog / Digital)
Setting the High Pass Filter value
To set the Highpass Frequency, perform the following, on the Input Configure page (Analog Inputs selected)
{p.87}:
1. Press the High Pass (#) Hz button. You are prompted to enter the highpass frequency in Hz.
2. Enter the frequency using the numeric keys. The valid frequency range is 30 Hz to 240 Hz.
Any value outside this range is placed near the closest valid number within this range.
3. Press High Pass (#) Hz button or the ENTER key to finish entering the Cutoff Frequency.
NOTE: The Cutoff Frequency value last entered becomes the default value for the next Cutoff Frequency.
Setting the High Pass Filter Frequency on Multiple Channels
To copy the Cutoff Frequency from part #1 to the appropriate channels, perform the following on the Input
Configure page (Analog Inputs selected) {p.87}:
1. Press the High Pass Filter button. (The button’s LED indicator flashes green while it is active.)
2. Press one of the Analog (#) buttons for the channel to which you want the highpass filter applied.
(The HPF indicator on the button changes to the selected Cutoff Frequency.)
3. Repeat #2 for each channel you want to change.
4. Once the last channel has been changed, press the High Pass Filter button again. (The LED stops flashing.)
NOTE: To disable the highpass filter, press the High Pass Filter button on the Input Configure page (Analog
Inputs selected) {p.87}, and then press the channel(s) you want to disable.
Enabling 48 VDC Phantom Power (Analog Only)
Some microphones require external power to operate. The Deva supplies the full power and current allowed by
the phantom power specification (48 VDC up to 1.0 A). The Deva does not supply 12T power, which is required
by some older microphones. If you use microphones requiring 12T power, check with your local audio dealer for
phantom to 12T power converters.
To enable phantom power, perform the following:
1. Press one of the Analog (#) buttons on the Input Configure page (Analog Inputs selected) {p.87}.
(The Analog Input (#) page {p.89} for that channel is displayed.)
2. Press the 48V (On / Off) button. (The text changes to 48V On indicating it is active.)
IMPORTANT: To protect equipment from damage, the Deva does not allow you to apply power to any channel
set as a line-level input.
Adjusting the Trim (Analog / Digital)
There are two ways to adjust the input trim on channels. If you have multiple inputs, the (Analog / Digital) Input
Trim page {p.111} allows you adjust all of them from a single page. However, if you are making individual
adjustments to channels, the trim can be adjusted using the on-screen fader in the Analog Input (#) page {p.89}.
Adjusting the Trim using the Analog / Digital Input Trim page
1. Press the Adjust Trim button on the Input Configure page (Analog Inputs selected) {p.87}.
(The (Analog / Digital) Input Trim page {p.111} is displayed.)
2. Press the meter for the channel you want to adjust.
(When a channel is activated, Trim: ?? dB changes to Trim: ?? dB.)
