Controls, Functions and Connections
Front Panel Refer to Reference Diagrams.
C Power Switch This switch provides control over the AC power from your wall outlet. When OFF (out
position) nothing on the amplifier is functional. When ON (depressed) the amplifier will
operate normally (green power LED indicates ON; Red Power LED indicates ON but in
MUTE mode).
D Standby Switch This switch when OFF (out position) will allow normal operation of the amplifier (indicat-
ed by the green Standby LED, assuming Power ON). When depressed ON the amplifier
will be placed in STANDBY mode and will not be operational (indicated by the red
standby LED, assuming Power ON). In this mode, a small amount of current will remain
flowing through the tubes, this reduces power consumption and extends tube life during
periodic short term non-use periods (i.e. during a listening session when interruptions
occur, or a short time prior to a listening session so the amplifier is warm and ready).
This mode also will keep optimal warm up times of the tubes shorter. For periods
between listening sessions extending over a 12 hour period, it is recommended that the
Power 2 is turned off via the Power Switch.
E Power LED When this LED is off, so is the amplifier. When the LED is glowing red, both chnnels are
Muted, controlled by the Input Selector Switches (I). When the LED is green, the amplifier
is receiving power and both inputs are selected, the amplifier is ready for operation.
(Green Power LED indicates ON; Red Power LED indicates ON but in MUTE mode;
Green + Red (Orange) indicates one channel is in MUTE and one channel is selected).
F Standby LED When this LED is off, so is the amplifier. When the LED is glowing red, this indicates the
amplifier is in Standby mode, controlled by the Standby Switch. When the LED is green
the amplifier is in operate mode.
Rear Panel Refer to Reference Diagrams.
G Detachable Power Plug the detachable Power Cord into this socket. The Power 2 amplifier is configured
Cord Socket for the operating voltages in which they are sold. See shipping box or Voltage/
Impedance sticker on rear of the chassis for voltage settings. If a different operating
voltage is required, please contact an authorized Sonic Frontiers dealer or the factory
directly.
H Fuse Location This socket/holder houses a 7 amp slo-blo fuse for countries with AC supplies
rated between 110-120V or a 3.5 amp slo-blo fuse for countries operating on
a 220-240V supply.
REPLACEMENT FUSES MUST BE RATED WITH THE SAME SPECIFICATIONS
AS THE ORIGINAL FUSE.
