When installing, carefully examine the place and method of installation for safety.

When using a stand, brackets, etc., follow the instructions included with the stand or brackets and check for safety before installing and using. DENON will accept no responsibility for damages or accidents caused by the unit falling.

Cautions on Installation – Speaker System (SC-A76, SC-C76)

The sound quality produced from the speaker system is affected by the size and type (Japanese or Western) of the room, as well as by the method of installation. Consider the points listed below before installing the speaker system.

■ Note that placing the speaker system on the same stand or shelf as a record player may result in howling.
If there is a wall, glass door, etc., directly in front of or behind the speaker system, cover the wall or door with a thick curtain to prevent resonance and reflection.
The speaker systems are of the low-leakage-flux type and can be used near televisions, but depending on the TV there may be color blotching on the picture. If this happens, turn off the TV's power, wait 15 to 30 minutes, then turn the TV's power back on. The TV's automatic degaussing circuit should reduce the blotching on the picture. If blotching persists, move the speaker further away.
When placing the (SC-A76 and SC-C76 speaker systems) on a stand, etc., stick the included anti-slip pads (cork, approximately 1 mm thick) at the four corners of the bottom surface. (Refer to the illustration right.)

When mounting the satellite speaker system (SC-A76) on a stand or bracket, you can use M5 nuts inserted into the bottom of the satellite speaker system (SC-A76) at intervals of 60 mm. When mounting, following the instructions in the manual included with the speaker stand or ceiling mount bracket, and be sure to install properly and securely.

CAUTION:

• To ensure safety, do not place any objects on top or lean objects against the speaker system.
• The speaker may topple down or fall if force is applied to the sides. Be particularly careful to avoid this, as this could cause injury or other serious accidents.

WARNING:

• When installing the speaker systems on the ceiling or wall, to ensure safety, have specialists do the installation work.
• Be sure to fasten the speaker cords to a wall, etc., to prevent people from tripping over them or otherwise pulling on them accidentally, causing the speaker systems to fall.
• Be sure to check for safety after installing the speaker systems. Afterwards, perform safety inspections at regular intervals to be sure there is no danger that the speaker systems will fall. DENON will accept no responsibility for damages or accidents caused by inappropriate choice of the place of installation or improper installation procedures.

[ Rear ]

■ Using the SC-C76 mounted on a wall:

The SC-C76 can be mounted on a wall using the key hole hooks on its rear panel.

To do so, install the two screws in the wall at a distance of 126 mm from each other (equal to the distance between the wall-mount bracket holes on the SC-C76's rear panel).

Once the screws are installed in the wall, insert onto the heads of the screws.

Be sure to mount to a solid wall strong enough to support the weight of the speaker system.

Note that DENON will accept no responsibility for damages due to the speaker systems falling.

CAUTION:

- If the speaker system is set in an unstable place, it could tip over or fall, possibly resulting in serious accidents.

Other Cautions – ALL (SC-A76, SC-C76, DSW-76)

Note that color blotching may occur on a TV, etc., due to interaction with the speaker system if there is a magnet or an object generating magnetic force nearby.

Example: (a) When there are magnets on the door of the rack, stand, etc.

(b) When a health device, etc., equipped with magnets is placed nearby.
(c) When toys or other objects using magnets are placed nearby.

■ Note that the illustrations in this instructions may differ from the actual set for explanation purposes.
■ Be sure to keep the operating instructions.

After reading these operating instructions, store them in a safe place. We also recommend filling in the necessary items on the back cover.

Cautions on Installation – Active subwoofer (DSW-76)

■ Note that placing the active subwoofer on the same stand or shelf as a record player may result in howling.
The DSW-76 active subwoofer is a Lowleakage-Flux type and can be used near televisions, but depending on the TV there may be color blotching on the picture. If this happens, turn off the TV's power, move the TV and subwoofer a little apart, wait 15 to 30 minutes, then turn the TV's power back on. The TV's automatic degaussing circuit should reduce the blotching on the picture. If blotching persists, move the subwoofer and TV further away from each other.
■ Install on a firm, flat floor to prevent accidents due to toppling down.
■ Do not place a record player, CD player or other AV device on top of the active subwoofer.

Other Cautions – Active subwoofer (DSW-76)

The built-in amplifier of the active subwoofer (DSW-76) includes a muting circuit. The output signal is strongly attenuated for several seconds after the power is turned on. If the volume is adjusted during this time, the output may be extremely high when the muting circuit is deactivated. Be sure to wait for the muting circuit to be deactivated before adjusting the volume.
Note that color blotching may occur on a TV, etc., due to interaction with the subwoofer if there is a magnet or an object generating magnetic force nearby.

Example: (a) When there are magnets on the door of the rack, stand, etc.

(b) When a health device, etc., equipped with magnets is placed nearby.
(c) When toys or other objects using magnets are placed nearby.

■ Note that the illustrations in this instructions may differ from the actual set for explanation purposes.
■ Be sure to keep the operating instructions.

After reading these operating instructions, store them in a safe place. We also recommend filling in the necessary items on the back cover.

WARNING:

- Be sure to fasten the power supply cord to a wall, etc., to prevent people from tripping over it or otherwise pulling on it accidentally, causing the subwoofer to fall.

1 Line input connector (LINE IN)

• Connect this to the AV surround receiver's (or amplifier's) pre-out connector ("SUBWOOFER", "MONO OUT", etc.) using the included connection cord (3-meter RCA pin-plug cord).
• To connect with a DENON AV surround receiver (or amplifier), connect this Line input connector to the subwoofer terminal on the rear of the surround receiver.

② Line output connector (LINE OUT)

• The signal input to the line input connector is output as such from here in parallel.
• When using two active subwoofers, connect the other active subwoofer's line input connector to this connector.

③ Phase selector switch (PHASE)

• This switches the phase of the output signal with respect to the input signal.
• Normally use the active subwoofer with this switch set at the “NORM.” position. If the continuity between the sound of the active subwoofer and the left and right speakers seems unnatural, try switching to the “REV.” position, and set the switch to the position in which the sound is most natural.

4 LF direct switch (LF DIRECT)

• When using the DSW-76 active subwoofer connected to a DENON AV surround receiver (or amplifier), if this function is turned on the signals bypass the active subwoofer's crossover and volume adjustment circuits, resulting in purer, higher quality sound we recommend turning the LF DIRECT switch (4) to the "ON" position. Note that when this is done the crossover adjustment control (5) and volume adjustment control (6) will no longer function.

5 Crossover adjustment control (CROSSOVER)

• This control only functions when the LF DIRECT switch (④) is set to the "OFF" position.
• This control sets the upper limit of the frequencies reproduced by the active subwoofer.
• Setting criteria

50 Hz : For left/right speakers with diameters of 20 cm or greater

100 Hz : For left/right speakers with diameters between 10 and 25 cm

200 Hz : For left/right speakers with diameters of 12 cm or less

- When using a Dolby Digital or dts-compatible AV surround receiver (or amplifier), we recommend turning the LF DIRECT switch (4) to the "ON" position and not using this function.

※ "Dolby" is a trademark of the Dolby Laboratories Licensing Corporation.
※ “dts” is a trademark of Digital Theater Systems.

About the AV surround receiver's (or amplifier's) crossover frequency selection:

The crossover frequency of the satellite speaker/center speaker and the active subwoofer (the boundary between the frequency range produced by the active subwoofer and the other speakers) is set on the connected AV surround receiver (or amplifier), and is usually fixed at between 80 and 120 kHz.

With some AV surround receivers (or amplifiers), however, including the DENON AV surround receiver (or amplifier), this frequency can be selected. When using this type of amplifier, the crossover frequency can be selected to suit your tastes.

When using the SYS-76HT with this type of amplifier, a richer sound can be achieved by setting the crossover frequency to around 135 Hz or the nearest value. Adjust the crossover frequency to suit your tastes. For instructions on switching, refer to your amplifier's operating instructions.

When connecting to a Dolby Digital or dts-compatible AV amplifier, whether one on which the crossover frequency is fixed or one on which it can be adjusted, we recommend setting the LF DIRECT switch of the active subwoofer (DSW-76) to the "ON" position.

⑥ Volume adjustment control (LEVEL)

• This control only functions when the LF DIRECT switch (4) is set to the "OFF" position.
• Use this control to adjust the volume of the active subwoofer.
• When turned clockwise ( ) from the center position, the volume of the active subwoofer increases, and when turned counterclockwise ( ), the volume decreases. Set to the desired position.
• For some signals, a very soft sound will be produced even when the volume adjustment control("LEVEL") is turned fully counterclockwise (○) and set to the minimum ("MIN"). This is not a malfunction.

If this should happen, connect the cord connected to the set's LINE IN connector to an output connector (SUB WOOFER PRE OUT, MONO OUT, etc.) for which the signals pass through the master volume circuitry of the AV surround receiver (or amplifier), etc., before being output.

Use the set's volume adjustment control ("LEVEL") to adjust the volume difference with the speakers other than the super woofer (front, center, surround, etc.), and adjust the overall volume using the master volume control on the AV surround receiver (or amplifier), etc.

7 Auto standby selector switch (AUTO STANDBY)

ON : The auto standby function is activated OFF : The auto standby function is deactivated

Auto Standby Function:

The AV surround receiver (or amplifier) is automatically set to the standby mode if no signal is input for 5 to 11 minutes, thereby saving electricity.

The power turns on immediately when a signal is input.

8 Status indicator

- The two-colored indicates the active subwoofer's operating status, as follows: Power "ON"......Lights green Auto power off (standby mode)......Lights red Power "OFF"......Indicator off Protective circuit activated......Flashing red

9 Power switch (POWER)

• The power turns on when this switch is set to the "ON" position.
• Several seconds are required for the set to begin operating. This is because the set includes a built-in muting circuit to prevent noise when the power switch is turned on and off.
• When set to the "OFF" position, the power turns off.

CAUTION:

• Do not plug the power supply cord into an AC power outlet until all connections have been completed.
• Check the left and right channels and be sure to interconnect them properly, L (left) to L, R (right) to R.
• Plug the power supply cord in securely. An insecure connection could cause noise.
• Note that clamping pin-plug cords and power supply cords together or running pin-plug cords near the power transformer could result in humming or noise.
• Check the polarities of the speakers and AV surround receiver (or amplifier) and be sure to interconnect properly. Connect the red terminal on the speaker to the “+” speaker terminal on the AV surround receiver (or amplifier), the black terminal on the speaker to the “−” speaker terminal on the AV surround receiver (or amplifier).

(1) Connecting the line input connector (LINE IN) – Active subwoofer (DSW-76)

※ Connect this to the pre-out connector for the active subwoofer on the AV surround receiver (or amplifier) ("SUBWOOFER PREOUT", "MONO OUT", etc.) using the included connection cord (3-meter RCA pin-plug cord).
