TOP-MOUNTED CONTROLS IN DETAIL
Top-Panel Power Switch and Indicator LED
The "Power" switch on the top panel determines the operational readiness of the
E-Sub subwoofer and should be the only switch used to turn the E-Sub on and off
during typical use.
The top-panel "Power" switch has three positions:
"Off ": The E-Sub's internal power amplifier is powered down.
Indicator LED: red
In this stand-by state, a tiny amount of power is consumed (< 0.5 watt) to
energize the E-Sub's soft turn-on circuitry.
"On": The E-Sub is fully operational.
Indicator LED: green
Power consumption will vary, depending on program material and level
"Auto": The E-Sub will power up its internal amplifier when it detects an audio
signal at any of its inputs, and will power down the internal amplifier if no
signal has been detected at its inputs for approximately thirty (30) minutes.
While dormant, the E-Sub consumes a tiny amount of power (< 0.5 watt).
Indicator LED: amber (dormant) / green (operational)
In the unlikely event that the Auto Turn-On feature is not sensitive
enough for a particular system, use a Y-cable adaptor (one female to
two male RCA type connectors) to split the incoming signal into both
RCA inputs on the E-Sub. This will increase the input sensitivity by
6 dB. Please be aware that if there is significant noise entering the
E-Sub's input, the E-Sub may not turn off as desired. If this happens,
remove the Y-cable adaptor and/or look for the noise source in the
upstream components.
The only way to completely power down an E-Sub is to unplug its AC Power
Cord. Before disconnecting the power cord, always place the top-panel "Power" switch
in the "off" position (to prevent damaging pops and transient noises).
Do not use a power strip switch, switched outlet or any other external switch to
interrupt or engage power to an E-Sub in "auto" or "on" positions, as this will also result
in undesirable and potentially damaging transient pops.
Master Level Knob
The "Master Level" Knob is used to set the output level of the E-Sub, relative
to the rest of the audio system.
When rotated fully counter clockwise, the E-Sub's output will be fully muted.
When at the "0" or straight up position, the level is at reference gain. When
turned fully clockwise, the E-Sub's level is at its maximum sensitivity (loudest).
