Unique Features; Plugging In Your Subwoofer - EMU PS12 Mode D'emploi

Unique Features

This section describes some of the unique features of the PS12.
Sub-Sonic Rumble Filter
The Sub-sonic rumble filter stops unwanted inaudible bass frequencies from playing through your PS12. Some very low
frequencies, (such as those below 20Hz), although inaudible, can cause rumbling of the cabinet, and even rattling of objects in the
listening room. The PS12 automatically filters these unwanted low frequency sounds out, reducing noise caused by rumble, and
increasing amplifier efficiency in the audible range.
Overload Protection
The PS12's built-in Overload Protection circuitry automatically engages when levels get too high, preventing potential damage to
the driver.
Foot Switch Input
The ¼" Foot Switch input accepts all standard latching or latch-type foot switches. A Foot Switch allows you to bypass the
subwoofer and its high-pass filter circuitry.
Pressing the Foot Switch puts the subwoofer on mute, and sends the full audio signal to the satellite outputs. This is extremely
useful is you want to A-B your source audio with or without the subwoofer.
High-Pass Filter Bypass Switch
If you want to hear the full unfiltered signal through your satellite speakers without bypassing the PS12, flip this switch to OFF.
With the high-pass filter turned off, the signal coming out of the satellite outputs is identical to the signal going into the
subwoofer.
Automatic Standby Mode
If no signal comes through your subwoofer for approximately 15 minutes, the subwoofer automatically enters low-power Standby
mode, muting all sound coming out of the subwoofer. When the PS12 detects a signal, it becomes active again.
When the PS12 enters standby mode, the Subwoofer Status LED turns Red. When the PS12 resumes to normal mode, the
Subwoofer Status LED turns green.
Selectable Voltage Operation
The Voltage Select switch on the PS12 allows you to select between 100-120V and 220-240V operation.
Check that the appropriate voltage is selected before powering up your PS12 for the first time.

Plugging in Your Subwoofer

Before you plug your subwoofer in for the first time, make sure that the Voltage Select switch just above the power connector is
in the appropriate position in accordance to the power outlet you're using.
Use the 115 Volt setting if you use AC power rated at 100-120 Volts (Most US power outlets).
