USB Connector:
    Connect to a USB 1.1 or USB 2.0 port using the included USB cable.

Status Light:
    GREEN: Power is on.
    GREEN FLASHING: Playing audio.
    RED: Muted (see below).
    YELLOW FLASHING: Detected a button pressed on the optional remote control.

Volume/Mute Control:
    Push up or down to adjust master volume.
    Push in to mute speaker outputs (status light turns RED.)

Multi-pin Socket 5.1 Channel Speaker & Headphones Output:
    Insert the Ear Force headphones multi-pin connector into this socket.
    The SRM includes six headphone amplifiers to drive the headphone speakers.
    An optional cable (available from www.TurtleBeach.com) may be used to
    connect 5.1-channel powered speakers. The jacks are color coded as
    follows:
        GREEN: Front Channels
        ORANGE: Center/Sub Channels
        BLACK: Surround Channels

Stereo Headphones Output:
    This jack is used to drive stereo headphones. The signals may be 
    changed by clicking the Speaker Options (…) button next to the Speaker 
    Configuration pull-down menu in the SRM control panel Speakers Tab. 
    When the Speaker Options is set to 7.1 speakers, channels 7 and 8 are 
    routed to this jack, while channels 1 – 6 are routed to the 5.1 channel
    multi-pin connector described above. 

Microphone Input (Stereo):
    Accepts mono or stereo microphones. Mic power is provided on both the 
    ring and tip of the jack. When a microphone plug is inserted into the
    jack, the internal microphones are disconnected. Microphone volume,
    gain boost and mono/stereo mic modes are accessed in the SRM control 
    panel Mixer tab. 

Stereo Internal Microphones:
    The internal stereo microphones are disconnected when an external mic 
    is inserted into the mic jack, or when the mic is inserted into the
    Ear Force surround sound headphones. 

Stereo Line Input (White) & S/PDIF Digital Input:
    Operates in two modes:
    1. Line Input: Accepts analog line-level sources, such as CD players,
       cassette players, etc..
    2. S/PDIF Input: Insert the included optical adapter into this jack to
       use it as an optical S/PDIF input for recording digital audio.

Stereo Line Output (Black) & S/PDIF Digital Output:
    Operates in two modes:
    1. Line Output: This line-level output is the same front channel stereo
       signal as the front channel (green jack) output on the 5.1- channel
       speaker cable, so they may be used simultaneously. This output can 
       only drive line level inputs such as powered speakers or line inputs
       on external recording devices. 

    2. S/PDIF Output: When the included optical adapter is inserted into
       this jack, it becomes an optical S/PDIF output for playing digital 
       audio. This allows for pass-through of Dolby® Digital and DTS® 
       multi-channel DVD sound to external A/V receivers or digital speaker
       systems. Settings for controlling S/PDIF functions are in the SRM 
       control panel Speakers Tab.

IR Remote Control Sensor:
    This sensor is for an optional infra red (IR) remote control, available
    at www.TurtleBeach.com. Aim the remote control at this sensor when using
    the remote control functions. When the remote control signal is sensed, 
    the status light will flash yellow.
