The “Mute” button mutes the output signal to the
loudspeaker terminals, headphone jack, as well as
both the fixed and variable line output connectors
(refer to the section entitled “Rear Panel
Connections” for further details). Pressing the
“Mute” button a second time will reinstate the
volume back to its previous level. When the output
signal is muted, the red LED to the right will
repeatedly flash on and off.
The “A2” input can be configured as a
‘pass-
through’ which bypasses the 340i’s gain control
section, allowing you to control the gain setting via
the connected source component’s own volume
control – a home theater processor for example; In
other words, this input operates like the input of a
power amplifier. In ‘pass-through’ mode ,
adjusting the volume on the 340i will have no effect
whatsoever when the “A2” input is selected. To put
the “A2” input into ‘pass-through’ mode , press
and hold down the “Mute” button for approximately
2 seconds while on the “A2” input. The front panel
display will change from “A2” to “HT”. To
reconfigure the “A2” input to function like the other
inputs, repeat the this procedure. Powering down
the 340i via the rear panel rocker switch will
automatically reset the the “A2” to the factory
default ‘normal’ mode.
The rotary “Volume” control determines the output
level. The volume control has an embedded red LED
to indicate its actual position.
The “Phones” jack is used for connecting a pair of
stereo headphones to the Nēo 340i. The input
connector is a standard ¼” stereo TRS jack. When a
pair of headphones are used with the 340i, the
loudspeakers will still receive an output signal.
However, you should use the aforementioned “Spk
off” button for private listening.
Optional Digital Inputs
The Digital Input option includes four (4) separate
inputs: “D1” uses an optical Toslink connector, “D2”
and “D3” use S/PDIF on an female RCA connector
and “D4” uses a type-B USB connector. The “D1” is
intended for use with a source equipped with a
TosLink digital output such as a satellite dish
receiver; The “D2” and “D3” inputs are intended for
use with a source equipped with a S/PDIF digital
output such as a DVD player, music server or disc
transport. The “D4” input is for use with a computer
equipped with a USB connector and music player
software such as iTunes or Winamp; you cannot
connect a USB flash drive or external hard drive to
to the “D4” input.
