YSS2 Active Studio Subwoofer
Connection
There are a couple of ways to connect the YSS2 to
your audio system. One method uses speaker cables,
the other method uses shielded cables with RCA type
connectors. Looking at the rear panel of the YSS2,
you will see two sets of spring terminals (one labeled
Input / From Amplier, the other labeled Output / To
Speaker) and two sets of RCA jacks labeled Input and
Output. The conguration of your present system will
determine how to connect to the YSS2.
Connecting a Dolby Digital or DTS System
All Dolby Digital and/or DTS processors have a subwoofer/
LFE output. If you decide to use a subwoofer/LFE output
connection (mono) to the YSS2, connect an RCA-plugged
patch cable from the subwoofer/LFE output to either the L
or R channels of the RCA Input jacks on the YSS2.
Getting Connected
Connecting to an Amplifier with no Preamp Outputs
If no line level preamp outputs are available, speaker cables need to be run from your main
power amplier to the YSS2 using the spring terminals labeled Input / From Amplier. Run
the main Left (L) and Right (R) speaker cables to the YSS2 Left (L) and Right (R) spring
terminals labeled Input / From Amplier. Be sure to double-check the polarity (+/-) on the
amplier (or receiver) and make sure it matches the polarity on the YSS2. Also, make sure
that the outputs of the main amplier are true ground; otherwise you would short the output
of your main amplier when connecting to the YSS2. Please call, or email technical support if
the outputs on your main amplier do not have true ground.
True Ground: When using a power amplifier’s outputs to send signal to the YSS2, the negative (-) lead
on the power amplifier must have continuity to the amplifier’s AC Ground pin on the power cord.
CAUTION: The power amplifier used to send speaker level signal to the YSS2 must NOT be bridged!
Rear Panel Descriptions and Functions
1. Power Switch
The Power switch has three positions; Off – Auto – On. While the Off and On positions are
self-explanatory, the Auto position tells the YSS2 to remain in Standby mode until the unit
senses an input signal.
Note: If the YSS2 does not receive an input signal for approximately 10-minutes, it will switch to Standby
mode until the unit senses an input signal.
When the unit is not used, turn the power off. When left unused for a long period of time,
the unit should be unplugged from the AC receptacle. Operate from an electrical power
source as specied on the unit or in the operating instructions.
2. Phase Switch
This switch toggles the phase of the subwoofer with respect to the main speakers. If the subwoof-
er is out of phase with the main speakers, bass response is at a reduced performance level and
may sound weak. When all speakers are in phase, full-frequency response is at an optimal level.
