Operation- Setting Mode- Output, Invert, Unbalanced Output, Dim - Lavry DA11 Manual

DA11
- If the input is not valid or not present, the DA11's input is not locked and the VOLUME display
indicates this by displaying "- -" instead of the numerical sample rate.
- Please see the USB INPUT section for detail of the display's operation with a USB source.
output-
One use for the output function is to mute the speakers while listening with headphones. The
output function "mutes" the main XLR outputs and does not affect the headphone output. To mute
the XLR outputs, enter the Setting mode and position the cursor above the "output" legend.
Click the right SELECT switch towards "set" to toggle the outputs On and Off.
- When the output LED is illuminated ("On"), the outputs are On.
- When the output LED is "Off," the outputs are Off (muted).
- Please note: this function is different than the MUTE function of the optional infrared remote,
which mutes all audio output from the DA11; including the headphone output.
invert-
The invert function affects the Polarity of both the main XLR outputs and the headphone output.
The consequence of incorrect Polarity is subjective, and is quite often subtle. This setting is
provided for two reasons:
1. To provide flexibility with output connection wiring.
2. To allow the signal polarity to be corrected when it is inverted due to polarity inversion in
the recorded music or other equipment/wiring in your system.
- Please note that this function operates in all configurations of the XLR outputs- balanced,
unbalanced Pin 2 Hot, and unbalanced Pin 3 Hot. The "sense" of the function is reverse for
unbalanced Pin 3 Hot operation and balanced "Pin 3 +" wiring (please see the chart below).
The Polarity of the signal affects the motion of the speaker reproducing the audio, and if incorrect
can affect the fidelity of the audio in a way that will vary with program material. If correct
throughout the recording and reproduction process, a positive air pressure at the microphone will
result in a positive pressure created by the speaker. If it is "inverted," the speaker will move in the
opposite direction and the resulting acoustic signal will be less accurate.
Enter the Setting mode and position the cursor above the "invert" legend. Toggle the function On
and Off with the Set switch. Below is a chart of the audio Polarity for different settings:

These functions are used to configure the XLR outputs for balanced, unbalanced Pin 2 Hot, or
unbalanced Pin 3 Hot operation, and do not affect the headphone output or signal polarity.
Balanced inputs are characterized by XLR connectors, and are typically wired so Pin 2 is "+"
(non-inverting) and Pin 3 is "-" (inverting). Unbalanced inputs are typically "RCA" (also called
coaxial "Cinch" connectors) or 1/4" phone jacks (similar to a large headphone plug with two
conductors). Most consumer HiFi equipment has unbalanced RCA inputs. Although no damage
will occur if these settings are not correct, connecting the DA11 to an unbalanced input with the
incorrect settings will result in higher than normal distortion or no sound. Please see the section
titled CONFIGURING THE XLR OUTPUTS for details on these settings.
dim-
This function adjusts the brightness of the front panel displays. When the function is On, the
displays are approximately one half as bright as when the function is Off.
