1. AC POWER TERMINAL (100-240V-50/60Hz 2.5A) - Universal power connector. Automat-
ically selects AC power mode (110VAC/220VAC) when connected to AC power. After all
connections have been made, connect the supplied AC Power Cord to an unswitched AC
power outlet.
2. IR SENSOR - IR sensor ‘sees’ the IR commands from the D2.1 IR Remote, or other properly
configured programmable remote to control D2.1 Power, Volume, EQ Input, etc.
3. LINE IN (L&R) - Two RCA jacks. Analog audio sensing input. When an audio signal is pres-
ent on these jacks the amplifier will turn ON. The amp will enter sleep mode when no
audio input has been sensed for a configurable delay to save energy. Using a stereo RCA
cable with gold ends, connect to the L&R line level audio output on a source to be played
though the D2.1. If the source has variable output be sure to lower the volume on the
source prior to turning the source and amp on the avoid unintentional damage to the D2.1
and/or speakers. Set source to an appropriate output level during audio level setup.
4. SUB OUT - One RCA jack. Outputs line level low frequency content to a powered
subwoofer. Using a mono RCA cable, connect to the Sub IN or LFE jack on a powered
subwoofer.
5. SPEAKER TERMINALS - Four -position plug-in screw terminal. Outputs speaker level audio
to left, right channel speakers or a sound bar. Using 16AWG (min) speaker wire, connect to
the appropriate speaker terminals on a sound bar or left and right speakers. Before con-
necting the speaker wire to the amp, twist the ends of the speaker wire so there are no
strays that can cause shorts.
6. OPTICAL IN - S/PDIF Optical Terminal. Digital audio sensing input. When an audio signal is
present on this terminal, the amplifier will turn ON. The amp will enter sleep mode when
no audio input has been sensed for a configurable delay to save energy. Using an optical
audio cable, connect to the Optical output of a TV or other device to be played through the
D2.1.
