Overview

The Tavor 8-Sub is an attractive powered Subwoofer that is used to reproduce the low-range audio frequencies (the bass) in a sound system. It has a control and connection panel as well as a woofer on its rear panel and a bass port facing downwards. The Tavor 8-Sub can be mounted on the wall, on the floor or next to the wall in a way that hides the control panel.

The Tavor 8-Sub powered subwoofer features:

• Three optional input methods:
  • A line-level stereo on RCA connectors to connect to the pre-amplifier output connector on a receiver/amplifier
  • An LFE input on an RCA connector to connect to the pre-amplifier output connector on a receiver/amplifier
  • A high-level input to connect to the subwoofer connector on the audio source as well as to the speakers directly
• A volume-level knob button
• A crossover frequency knob button (65Hz to 150Hz)
• Two optional power settings (110-120V or 220-240V)
• An optional auto standby mode
• Reverse phase selection (0 or 180 degrees)

The Tavor 8-Sub is enclosed in a wooden cabinet.

Installing the Tavor 8-Sub

This section explains how to:

• Choose the best location (see Section 5.1)
• Install the wires (see Section 5.2)

Section 5.3 describes the different subwoofer setups.

Choosing the Best Location

You can position your Tavor 8-Sub in three ways:

• On the floor with the woofer facing the floor (horizontally placed)
• On the wall with the woofer facing the wall and the bass port facing downwards (see Section 6)
• On the floor vertically with the woofer facing the wall and the bass port facing the floor.

Ensure proper air relief by sticking the four self-adhesive rubber feet firmly into place, creating free space around the bass port.

Make sure that you:

• Keep the vibrations to a minimum
• Do not cover or place anything on the Tavor 8-Sub

Before installing the subwoofer:

• Experiment with different locations to check the sound quality before finalizing the placement (see installation instructions in Section 5.2). The ideal place is between the two front speakers, but other locations may work well.
• Avoid placing the subwoofer directly in the central dividing line of the room; it should be located toward the left or the right of the central dividing line.

Installing the Tavor 8-Sub

1. Connect one of the optional inputs to a receiver or to an active speaker (see Section 5.3).
2. Connect the power.
3. Press the ON switch.
4. If the subwoofer is located in front of the listeners (next to the front speakers), set the phase to 0°. If it is located behind them (next to the rear speakers), set it to 180°.
5. To further optimize the subwoofer phase, follow these steps:
   • Sit at the center of the main listening area.
   • Play an 80Hz signal through your audio system.
   • Measure dBSPL in both 0° and 180° degrees settings (using your ears for loudness or via an application or a dB meter).
   • Whichever setting produces a louder sound (higher dBSPL) is the recommended setting to use.
6. Set the Crossover frequency knob to the lower range of the main speakers (if the main speakers have a frequency response of 100Hz to 20kHz, set the crossover frequency to 100Hz).
7. Turn the volume all the way down.
8. Play a track with deep bass and rich in low frequencies.
9. Listen to the bass line and set the Tavor 8-Sub volume to the point where the bass sounds most balanced. The subwoofer should not be louder compared to the rest of the system; it might sound muddy or ‘boomy’.
10. Fine-tune the Tavor 8-Sub volume and crossover frequency where it sounds best and blends smoothly with the rest of the speakers’ sound.

Note: If you decide to place the Tavor 8-Sub vertically on the floor, you need to stick the four self-adhesive rubber feet firmly into place to create some free space around the bass port and ensure proper air relief.

Tavor 8-Sub Different Setups

The Tavor 8-Sub offers various optional setups for connectivity:

1. LFE Input (Recommended for Surround Systems) : Connect it directly to an amplifier/receiver using the LFE (Low Frequency Effects) input. For detailed instructions, refer to Section 5.3.1.
2. Line Level Input : Utilize the LINE LEVEL INPUT for connection, as explained in Section 5.3.2.
3. High-Level Input : Connect using the HIGH LEVEL INPUT as described in Section 5.3.3.
4. Active Speaker Connection : Alternatively, you can connect the Tavor 8-Sub to an active speaker, following the guidelines in Section 5.3.4.

Important Note : Sending a 50W input to the Hi-Level inputs while setting the full volume on the LFE inputs may potentially damage the Tavor 8-Sub.

Connecting to a Receiver via the LFE Input

Some receivers feature an LFE or pre-out connector, designed for low-frequency effects channels, typically used in Dolby® Digital or DTS® surround systems. To establish a connection via the LFE input, follow these steps:

1. Connect the Pre-out, LFE, or Subwoofer Out (or a similar name) RCA connector on the receiver.
2. Link it to the LFE input on the Tavor 8-Sub using an RCA cable.

To connect via the LFE input, connect the Pre-out, LFE, or Subwoofer Out (or any other similar name) RCA connector on the receiver to the LFE input on the Tavor 8-Sub via an RCA cable.

Figure 4: Connecting via LFE

Connecting to a Receiver via the Line Level Input

If the receiver/processor has Subwoofer outputs (and does not include Dolby® Digital or DTS®) use the Subwoofer outputs to connect to the subwoofer:

1. Connect the receiver subwoofer output left RCA connector to the L LINE LEVEL INPUT RCA connector, via an RCA cable.
2. Connect the receiver subwoofer output right RCA connector to the R LINE LEVEL INPUT RCA connector, via an RCA cable.

Use the CROSSOVER control button on the Tavor 8-Sub to set the optimal crossover frequency of the system.

Figure 5: Connecting via Line Input

Connecting to a Receiver via the High-Level Input

If the receiver does not have a dedicated subwoofer output, connect it to the Tavor 8-Sub using the receiver’s speaker outputs via regular speaker wires. The low frequencies will be set via the Crossover control knob.

To connect via the high-level input:

1. Connect the Left + and – speaker output connectors on the receiver to the + and – L HIGH-LEVEL INPUT connectors on the Tavor 8-Sub, respectively, using speaker wires.
2. Connect the Right + and – speaker output connectors on the receiver to the + and – R HIGH-LEVEL INPUT connectors on the Tavor 8-Sub, respectively, using speaker wires.

Figure 6: Connecting via High-Level Input

Connecting to an Active Speaker via the Line Level Input

When using an active speaker, for example, the Tavor 5-O, you can connect the Tavor 8-Sub directly to the speaker via its SUB OUT connector using the Kramer Mini Jack (3.5mm) to RCA cable (C-A35M/2RAM) as illustrated in Figure 7:

Figure 7: Connecting to an Active Speaker

Wall Mounting

Mounting the Tavor 8-Sub on the Wall

You can place the Tavor 8-Sub vertically or horizontally or use the specially designed wall mount bracket included in the package to hang the Tavor 8-Sub on the wall at the desired location.

To mount the Tavor 8-Sub onto the wall:

1. Run the wires from the receiver to the Tavor 8-Sub desired location.

2. Mark the desired location of the wall bracket. And prepare the wall for mounting the bracket (installing four masonry anchors for the support screws).

3. Screw the bracket in place:
   Figure 8: Installing the Bracket

4. Pass the wiring through the opening in the bracket.

5. Lift the Tavor 8-Sub and place the groove on the subwoofer over the bracket.
