GROEBENZELL, GERMANY K. MIYAGI ONKYO EUROPE ELECTRONICS GmbH 3 SKW204_En Page 4 Monday, March 20, 2006 9:22 AM Precautions—Continued Supplied Accessories Placement • Pin connector cable 10 ft. (3 m) • The subwoofer cabinet is made out of wood and is therefore sensitive to extreme temperatures and humidity, do not put it in locations subject to direct sunlight or in humid places, such as near an air conditioner, humidifier, bathroom, or kitchen. • Do not put water or other liquids close to the subwoofer. If liquid is spilled over the subwoofer, the drive units may be damaged. • Subwoofer should only be placed on sturdy, flat surfaces that are free from vibration. Putting it on uneven or unstable surfaces, where it may fall and cause damage, will affect the sound quality. • Subwoofer is designed to be used in the upright vertical position only. Do not use it in the horizontal or tilted position. • If the subwoofer is used near a turntable, CD player or DVD player, howling or slipping of sound may occur. To prevent this, move it away from the turntable, CD player or DVD player, otherwise lower the unit’s output level. 4 • Power-plug adapter Only supplied in certain countries. Use this adapter if your AC outlet does not match with the plug on the AV Receiver’s power cord. (Adapter varies from country to country.) * In catalogs and on packaging, the letter added to the end of the product name indicates the color of the SKW-204. Specifications and operation are the same regardless of color. SKW204_En Page 5 Monday, March 20, 2006 9:22 AM Controls FRONT VIEW A Standby/On indicator (STANDBY/ON) This indicator lights up when the power switch is set to the ON position. Red: The unit is in Standby mode Green: The unit is in Operational mode If the power is turned on, the SKW-204 automatically enters Operational mode when a signal is input. The SKW-204 automatically returns to Standby mode when no signal has been input for a while. 1 REAR PANEL North American Model 2 Other Models 3 4 5 6 To AC outlet B POWER switch Press this switch to the ON position to turn on the power. Press it to the OFF position to turn off the power. C FREQUENCY knob Use this knob to select the high-frequency range at which to cut off the signal to the subwoofer. You can select any frequency between 50 Hz and 200 Hz, depending on the characteristics of the speaker system. D PHASE switch Use this switch to reverse the phase of the SKW204. Normally, set the switch to the “NOR” position. Depending on the connected speakers or the installation environment of the SKW-204 however, the “REV” position may result in better sound. Select the switch position that produces a louder bass sound. 7 (Only some models) To AC outlet E OUTPUT LEVEL knob Use this knob to adjust the volume of the subwoofer. F LINE INPUT jack Connect this jack to the SUBWOOFER PREOUT jacks on the amplifier etc. G VOLTAGE SELECTOR (Only some models) This voltage selector provides compatibility with power systems around the world. Note: The auto standby function engages if the input signal level is constant. If the auto standby function does not operate properly, try slightly increasing (or decreasing) the subwoofer output level of the receiver. 5 SKW204_En Page 6 Monday, March 20, 2006 9:22 AM Connections Subwoofer effects For safety considerations, turn off all other system components before you connect or disconnect any component and plug the power cable for the last. Adding a subwoofer to your speaker system expands the bandwidth of the bass range. However, if the subwoofer’s reproduction bandwidth or sound output level is improperly adjusted, the overall performance may decrease, as shown in the graphs below. Using the SKW-204 with an AV amplifier When using the SKW-204 in conjunction with an AV amplifier or receiver that features surround capability, connect the SKW-204 LINE INPUT to SUBWOOFER PREOUT jack using the supplied pin connector cable. SUBWOOFER PREOUT When the subwoofer’s reproduction bandwidth is correct Overall characteristics Speaker characteristics Subwoofer characteristics When the subwoofer’s output level is incorrect (Supplied) Output level is too high SKW-204 Output level is too low When the subwoofer’s reproduction bandwidth is far from the speaker’s bandwidth Curve is sunken When the subwoofer’s reproduction bandwidth is close to the speaker’s bandwidth Curve is raised 6 SKW204_En Page 7 Monday, March 20, 2006 9:22 AM Adjustments Troubleshooting Crossover frequency and output level The unit does not turn on • Adjust the SKW-204 output level and crossover frequency to suit your listening room and connected speakers. • Be aware that you might set the subwoofer to a high output level because superbass-range sound is less audible than other sound ranges. To obtain well-balanced frequency characteristics, set the output level to a slightly lower level than seems optimal. (This will also prevent the input of signals that are too strong.) • The power plug is not fully inserted. ➞ Insert the power plug fully into the power outlet. Note: Be careful not to allow the input of excessive power. Input levels that greatly exceed normal situations can damage the SKW-204. Also note that switching operations at the amplifier may generate excessive noise that may result in damage. When using switches at the amplifier, first lower the volume to prevent accidental damage. No sound is output • The OUTPUT LEVEL knob is set to the MIN level. ➞ Set the OUTPUT LEVEL knob properly. • Pin connector cable is not properly connected to the LINE INPUT jack. • The speaker setting at the amplifier (or receiver) is incorrect. ➞ Check the settings at the amplifier (or receiver). • The input signal is so small that the unit entered Standby mode. ➞ Slightly increase the output level at the amplifier (or receiver). Low sound output • The sound source might not include a superbass range. ➞ Play a sound source that includes a superbass range. Placement Hum noise The placement of the SKW-204 can greatly affect the sound that is produced. In general, a good bass sound can be obtained by installing the subwoofer in a front corner, or at one-third the width of the wall, as shown. • Pin connector plug is not inserted completely. ➞ Fully insert the pin connector plug. • External leakage flux (induction noise by TV, etc.) occurs. ➞ Relocate the SKW-204 away from the noise source and re-connect.
