The “Mute” button mutes the output signal to the
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 350P’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 350P 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 “Monitor” 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 350P 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 350P. The input
connector is a standard ¼” stereo jack. When a pair
of headphones are used with the 350P, the output
signal will continue to be sent to the amplifier(s)
connected to the 350P.
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
the “D4” input.
