Crossover Switch
The subwoofer direct switch will disengage the built-in crossover in the DECO 8 subwoofer and is designed to be used with a home theater receiver which has a built in crossover. Set this switch to the “SUBWOOFER DIRECT” position when you are using a home theater receiver with a subwoofer (LFE) output that has a built in crossover. If the “Subwoofer Out” or “LFE Out” in the receiver or processor offers an adjustable crossover frequency, we recommend you experiment with this setting. A crossover frequency from 100-120 Hz will work best in most installations, allowing output from the DECO subwoofer and satellite speakers to blend together seamlessly. Refer to the receiver owner’s manual for instructions on adjusting its crossover frequency.
For all other installations which do not have a separate electronic crossover, we recommend you leave the switch to “INTERNAL X-OVER” and set the crossover knob to “DECO Setting” for optimum system performance (see Figure 8 page 14).
Auto/On Power Switch
With this switch in the “AUTO” position, the subwoofer can be safely left with the master power switch on continuously. The subwoofer will power up automatically when an audio signal is present. If no signal is present for approximately 10 minutes, the unit will switch to a standby mode. The subwoofer will draw very little power while in the standby mode. Leaving the master switch in the “ON” position will keep the subwoofer powered whenever the master power switch is on.
Master Power Switch
The master power switch is located on the back panel of the subwoofer. If the unit is to be left unused for an extended period of time, the master power switch should be turned off to prolong the life of the subwoofer and conserve energy.
CONNECTING THE DECO HOME THEATER SYSTEM
CONNECTING THE DECO SATELLITES
Velodyne recommends installing the DECO Satellite speakers with 16 AWG (American Wire Gauge) or larger speaker wire. Always switch off all your equipment before making any connections. Be very careful to observe polarity (see Figure 5 below) when connecting the positive (Red +) terminal on the receiver to the positive (Red +) terminal on the speaker; and the negative (Black -) terminal on the receiver to the negative (Black -) terminal on the speakers. Connecting these wires improperly will adversely affect the sound quality of the speaker system. Look carefully at the type of wire you are using. The wire you are using may be identified with a different color, printing, ridges or colored thread marks on one of the wire strands. By convention the marked (or colored) wire is connected to the positive (Red) terminals. Make sure that all of the wire strands are inserted into the terminals so that there are no loose strands. To connect the speakers, remove approximately ½” of insulation from the end of each wire. Twist the strands of each wire into a tight bundle, depress the terminal and insert into the hole on the side of the terminal. The DECO Satellites are designed to accept individual banana plugs. The banana plugs should be inserted into the hole on the top of the gold plated terminal (see Figure 7 page 13 for typical
