Logitech SoundMan Xtrusio DSR-100

There are two different options for making the audio connections in the system.  For those users whose sound card offers a multichannel digital audio connection such as the SoundBlaster Live!,  it is essentially one connection that has four conductors for two separate stereo audio channels (front and rear).  There are also two adaptors included that will adapt to a multipin connection or RCA coax connection.  This system makes for an extremely easy connection to the audio card while still maintaining a high quality digital connection.  Also provided are two stereo cables for analog connections to stereo front and rear outputs on a four channel soundcard that does not offer the digital output.  When both the analog connections and the digital connections are connected, the speaker system will default to the digital connection.

The last thing to connect prior to the main power is the wired remote.  It connects to the subwoofer unit via a multi pin connector and prewired cable.   The remote contains the standby button (the main power switch is on the subwoofer), a front to rear fader control, volume fader, and headphone jack.  It has a rather small profile that will not take up desk space, though could get lost in the clutter.  When headphones are connected, the main speakers are muted.  For those without a front panel headphone connection the convenience of having a desktop connection is valuable.

Finally, the main power is connected.  The power supply is universal; it will automatically switch to voltages between 90V and 240V AC.  The power supply is internal so there is no bulky wall wart to take up space on the wall or power strip; both the amplifiers and power supply are integrated into the subwoofer enclosure.  Once all of the connections are made, the main power switch on the sub can be engaged, and then the sub can be finally placed.  Moving it towards a wall or beneath a desk can increase the boominess of the sub by helping to reflect more of the bass towards the listener.

The final step in configuring the system is tuning it to the individual preferences of the listener.  On the side of the sub are two tonal controls allowing for changes in the sound at the 100 Hz and the 10 kHz levels.  Once these are initially adjusted for personal preference, the sub can be tucked away as volume and power are controlled by the remote.
