FRONT PANEL CONTROLS IN DETAIL
Power Switch
The "Power" switch determines the operational readiness of the Fathom IWSv2
system and should be the only switch used to turn the Fathom IWSv2 amplifier on
and off. Do not use a power strip switch, switched outlet or any other external switch
as these may result in undesirable and potentially damaging transient pops. Do not
unplug the Fathom IWSv2's AC power cord while the unit is turned on.
The power switch has three positions:
"off": The Fathom IWSv2's power amplifier is powered down. In this state, a
negligible current draw will exist for operating the main power relays. All front
panel lights are off .
"on": The Fathom IWSv2 amp is fully powered at all times. Front panel lights are
on unless they have been turned off via the "Lights" switch.
"auto": In this position, the Fathom IWSv2 amp can be activated by the following
methods:
Signal Sensing: In this mode, the Fathom IWSv2 amp will power up when
an audio signal is present at any of its inputs and will power down its internal
amplifier when no signal has been detected at its inputs for thirty (30) minutes.
When dormant, the Fathom IWSv2 will draw a very small amount of current
(< 10 watts) to power its Signal-Sensing circuitry. Front panel lights will turn
off when the Fathom IWSv2 powers down and light when the Fathom IWSv2
powers up (unless they have been turned off via the "Lights" switch).
Note: In the unlikely event that the Auto feature is not sensitive enough for
a particular system, use a Y-cable adaptor to split the incoming signal into
both RCA or XLR inputs on the Fathom IWSv2. This will increase the input
sensitivity by 6 dB. Please be aware that if the Auto sensitivity is too high or if
there is significant noise on the input cable, the Fathom IWSv2 may not turn
off as desired. If this happens, remove the Y-cable adaptor or look for the noise
source in the upstream components.
12V Trigger: Optionally, the Fathom IWSv2 amp can be activated using a 12V
DC signal. To enable this mode, flip the "12V TURN-ON" switch located on
the back panel (see page 20) to the "On" position. This setting overrides audio
Signal-Sensing and will only turn on the Fathom IWSv2 amp when a 12V DC
signal is present at its "12V Trigger – In" connection. When the 12V DC signal
is removed, the Fathom IWSv2 amp will enter Standby mode immediately.
Front panel lights will turn off when the Fathom IWSv2 powers down and
light when the Fathom IWSv2 powers up (unless they have been turned off via
the "Lights" switch).
Note: Whenever the Fathom IWSv2 amp is ON, its "12V Trigger – Out"
output will be active, regardless of the "12V TURN-ON" switch's position.
This allows you to control multiple Fathom IWSv2 amps using a single 12V
trigger lead by daisy-chaining them together ("12V Trigger – Out" activates
the "12V Trigger – In" of the next amp, etc.).
