Features
Rear Panel
1.
Power Input:
Use the included IEC power
cable to connect this input to a power
source.
2.
Fuse:
If the unit's fuse is broken, lift this
tab to replace the fuse. Replace it with a
fuse with an appropriate rating (printed
under the unit's power cable input). Using
a fuse with an incorrect rating can damage
the unit and/or fuse.
3.
Power Switch:
Use this switch to power
the loudspeaker on or off.
4.
Power/Standby LED:
This LED illuminates
when the loudspeaker is powered on.
5.
Standby On/Off Switch:
By default, this
loudspeaker has its Standby Mode
enabled: when no incoming audio signal is
detected for approximately 15 minutes, the
loudspeaker will enter a low-power state.
The loudspeaker will exit Standby Mode within 0.5 seconds of detecting an incoming audio signal. Change
this recessed switch's setting to the
Off
position to disable this feature.
6.
Logo On/Off Switch:
Press this to turn the light in the Denon Professional logo on or off.
7.
Line/Mic Switch:
Engage (depress) this switch if your Input 1 audio source is a microphone. Disengage (raise)
this switch if your Input 1 audio source is line-level.
8.
Input 1:
Use a standard XLR or 1/4" (6.35 mm) cable to connect your audio source to this input. This input
accepts both line-level and microphone-level sources. Set the Line/Mic Switch to the appropriate setting.
9.
Input 2:
Use a standard XLR or 1/4" (6.35 mm) cable to connect your audio source to this input. This input
accepts line-level sources only.
10.
Input Volume Knob:
Use this knob to set the level of the audio going into its corresponding input below.
When connecting to the output of a pro audio mixer or signal processor, we recommend setting this to the
0 dB
setting; the Delta Series loudspeaker's gain structure is optimized for standard XLR or 1/4" (6.35 mm)
maximum signal levels of +10 dB RMS/continuous (+20 dB peak) from your source. Such devices include live
sound audio mixers, rack mount signal processors, DJ mixers, etc.
11.
Signal/Limit LED:
This LED illuminates
green
when an incoming audio signal is detected. It illuminates
red
when the audio signal level is too high and is being dynamically reduced to protect the loudspeaker from
damage or distortion. If this LED is continually illuminated red, or if the audio output sounds excessively
distorted, then reduce the volume of the connected audio source, or reduce the setting of the Input Volume
Knob.
12.
Mix Out:
Use a standard XLR cable to connect this balanced output to the input of a second Delta Series
loudspeaker. Audio is sent from this output at
0 dB
, depending on the setting of the Output Mix Switch.
13.
Output Mix Switch:
In the "out" (raised) position, the Mix Out is the sum of Input 1 and Input 2, pre-volume
(i.e., the Input Volume Knobs do not affect the audio signal level of the Mix Out). In the "in" (depressed)
position, the Mix Out is the sum of Input 1 and Input 2 but adjustable with the Input Volume Knobs.
14.
Ground Switch:
Engage (depress) this switch to reduce hum or noise.
15.
DSP Mode Button:
Press this button to set the loudspeaker's internal DSP to any of the following settings:
•
Flat:
No change to the audio.
•
Contour:
Boosted bass and treble with a gradual cut of mid-range frequencies—a useful setting for
most contemporary music.
•
80Hz HP:
Applies a high-pass filter. This is useful when using the Delta 12 as a crossover with a
subwoofer that does not have a high-pass output. This setting is also useful for cutting all bass
frequencies (e.g., for in speech-only applications, or when used as a delay or fill loudspeaker where the
extra bass frequencies are not needed).
•
Ext LF:
Extends the loudspeaker's low-frequency response, providing increased output of bass
frequencies.
•
Custom:
Applies your custom DSP mode, set in the Live Drive app.
16.
Pairing Button:
Press and release this button to pair the loudspeaker to your iPad, iPhone, or iPod touch. The
Pairing LED will illuminate when it is paired. See the
Bluetooth Pairing
section for instructions.
