Prior to Installation:
Be sure to unpack the system carefully to avoid damage. This unit is heavy so use caution when lifting or moving to avoid injury. Save the carton and all packaging materials for future use. Packing this unit in any other carton may result in severe damage when shipping. Be sure to record the serial number for future reference.
Prepare for Installation:
Teledyne Acoustics VI-Q subwoofer provides for a number of installation options. We suggest reviewing all the installation information below in order to determine which installation option is best for your system. Remember to perform all installation procedures with system power turned off to prevent possible damage.
Placement
The first step in installing your new VI-Q subwoofer is to determine where it will be placed in the room. You can use the following guidelines in order to find the best room placement to maximize your listening enjoyment.
True subwoofers operate at extremely low frequencies, which are primarily omni-directional. Keep in mind that frequency response and output level can be drastically influenced by placement and the acoustic properties of the listening room. When using a pair of Teledyne Acoustics subwoofers in 2- channel stereo, it is preferable to feed each subwoofer with one channel and place each subwoofer near the satellite of the same channel.
The perfect placement for your subwoofer will depend on room size, furnishings, and other unique variables in your listening space. Finding the best location for your subwoofer will likely require some experimentation. We suggest you use your favorite spot for listening to music or watching movies while experimenting with the location of the subwoofer during setup. This will allow you to find what sounds best to you when seated in your typical listening position. Regardless of where you install your Teledyne Acoustics subwoofer, it must remain in an upright position. Placing, shipping, or storing your subwoofer in any other position for an extended period of time may result in damage to the unit. This type of damage is not covered under warranty.
This subwoofer has electronics built into the cabinet. Because of this, your subwoofer should not be placed next to sources of heat such as furnace registers, radiators, etc. Do not place the unit near sources of excessive moisture, such as evaporative coolers, humidifiers, etc. The power cord should be routed in such a way that it will not be walked on, pinched or compressed in any way that could result in damaging the insulation or wire.
Teledyne Acoustics VI-Q subwoofers are NOT magnetically shielded. Should you find it necessary to use it with an older CRT monitor or TV, keep it at least two feet from the monitor. Experiment for correct distance by minimizing distortion of the picture and colors.

REAR PANEL CONNECTION

1. SPEAKER LEVEL INPUT TERMINALS – Connect these input jacks to the speaker output jacks on your amplifier or receiver.
2. LINE / LFE INPUT RCA JACKS – Connect these jacks to the LINE OUT jacks of your amplifier.
3. LINE / LFE OUTPUT RCA JACKS – Connect these jacks to the LFE IN jacks of an additional subwoofer to achieve linking.
4. XLR / BALANCED INPUT JACKS – Connect these jacks to the XLR OUT jacks of your amplifier.
5. XLR / BALANCED OUTPUT JACKS – Connect these jacks to the XLR IN jacks of an additional subwoofer to achieve linking.
6. AUTO POWER SWITCH – OFF: Unit is in standby mode / Auo: Unit is in operation mode / ON: Unit is on. If there is no signal for 8 minutes, the subwoofer automatically switches to standby mode.
7. PHASE CONTROL – Adjust the position where you hear a louder sound in the mid-bass range.
8. PAIRING INDICATOR – LED that signalizes the state of communication with the APP.
9. VOLUME LEVEL CONTROL – Use this control to adjust the output power of the subwoofer.
10. LOW-PASS CROSSOVER – Use this control to select the high frequency range at which you want to cut the signal to the subwoofer.
11. 12V TRIGGER IN – This will automatically turn the subwoofer on when a 12V signal is sent to this trigger input from another component in the system (typically the Preamplifier or AV receiver). The other component in the system must be equipped with a trigger output feature and requires a 3,5mm min jack mono cable.
12. DSP ON – Use this switch to activate the woofer app.
13. POWER CONNECTION, FUSE TYPE – T8AL 250V for AC120V~60Hz, T4AL 250V for AC230V~50Hz.
14. POWER ON/OFF SWITCH – Turns the subwoofer on or off.
15. 5V USB POWER OUTPUT – Can be used to power the optional WI Connect System II wireless transceiver.

XLR CONNECTION

Teledyne Acoustics’ flagship subwoofers also have XLR connectors. With long signal paths, this type of connection is less susceptible to interference than standard RCA cables. For this reason, XLR cables are mainly used in studio and stage technology, but are
now also increasingly finding their way into home theater or hi-fi setups.

STEREO CONNECTION

LFE CONNECTION

The LFE channel (Low-Frequency Effects) is used in various multi-channel systems such as 5.1, 7.1 or even 3D audio to transmit low tones that cannot be accurately located by the human ear. In most cases, this channel is designed for the limited frequency range of something 20 – 100 Hertz, which also allows for a data-saving transmission. On the AV receiver, it is usually labeled „SW“ for subwoofer, „Sub Out“ or, as on the VI-Q subwoofers, „LFE“. If the crossover of the AV receiver is then used, the subwoofer should be  set to „Subwoofer Direct.“

HIGH LEVEL CONNECTION

Older stereo amplifiers and even some current models do not have an LFE jack or a line connector for RCA plugs. But even these audio devices can be easily connected to a Teledyne Acoustics woofer via speaker terminals. The front speakers of the system are wired in parallel with the amplifier and the subwoofer. With this type of connection, the subwoofer‘s crossover removes all high and mid frequencies and only bass is reproduced. It is important that „Subwoofer Direct“ is not used with this setting. Also, both channels should be connected because they may contain different bass information that would otherwise be lost during playback.

INTERCONNECT CABES
During installation of your Teledyne Acoustics VI-Q subwoofer using the line level connections, you should always use shielded RCA cables. There are many high quality cables available today. It is recommended that you keep the length of cable as short as possible to avoid any potential noise problems.
When using speaker level connections, use a high quality speaker cable that mates well with the connectors. Be careful to avoid any loose strands or frayed wires that may result in a short, which could damage your equipment. Be aware that cables of extremely large size are not required due to the low current draw of this type of connection. Please note that extremely large gauge wire may not properly fit in the terminals, resulting in a poor connection and possible short circuits.
CARE OF YOUR SUBWOOFER
In regards to care of your Teledyne Acoustics subwoofer, normal dusting or cleaning of the surface for appearance purposes is all that is required. We suggest you avoid any harsh detergents or chemicals when cleaning the cabinet. The finish on the cabinet may become damaged with the use of abrasives, detergents, or cleaning solutions. We highly recommend using only a damp cloth to clean the cabinet.
Under normal conditions, your subwoofer may be left on continuously without any problems. The unit is equipped with a signal-sensing on/off circuit that will automatically turn on the unit when a signal is present at the inputs and turn off the unit after several minutes when there is no longer any signal at the inputs.
PROTECTION CIRCUITRY
Your Teledyne Acoustics subwoofer is equipped with circuitry to provide maximum performance with greatest reliability.
The unit is protected against:

1. Overheating the amplifier.
2. Excessive drop in power line voltage.

If either of the above should happen, you should reduce the volume setting or shut the unit off until normal operating conditions return. You may also want to plug the unit into a different wall outlet, as dropping power line voltage will be most noticeable under strenuous conditions and may result in the unit shutting down intermittently.
TROUBLESHOOTING AND SERVICE
Please re-check all systems and verify your connections and settings before contacting an authorized service center.
Following is a simple troubleshooting guide to assist you.
Verify that the unit is plugged in and power outlet used is active.

1. Is the power switch on?

2. Is the unit receiving an input signal from your source?

3. Have all controls (volume, crossover, phase, etc.) been properly set?

4. If the unit has been running at high levels, one of the protection circuits may be engaged.
   Has the amplifier overheated?

5. Make sure the speaker wires are fully inserted into the spring clip connectors and that no wires are touching from one terminal to another.

If the protection circuitry is active, the unit may cycle on and off until operating parameters return to normal. Under more serious conditions, the unit may shut off completely. Upon cooling, normal operation should return. However, you may be required to turn the power off and then on again to reset the unit before it will operate normally again.
The following conditions require service by a qualified technician:

1. The power cord has become damaged or appears damaged.
2. The unit does not appear to operate normally or exhibits a marked change in performance.
3. The unit has been exposed to water.
4. Some part of the cabinet or circuitry is physically damaged.

SERVICE

What is the crossover frequency and how is it set?
The crossover frequency is set to a specific frequency depending on the speaker system. Often 80 hertz is recommended to start, allowing the subwoofer to reproduce frequencies below this level while filtering out higher frequencies. Most subwoofer crossovers are user-adjustable (e.g., from 50 Hz to 180 Hz on the VI-Q series), so you can find an exact match for your system at home. The goal of the setting is a seamless transition between the main speakers and the subwoofer, which means that bass can no longer be located in the room at best. If you can hear exactly that the bass is coming from the direction of the subwoofer when listening to music or watching movies, the setting needs to be adjusted. If the main speakers of the system are full- grown 3-way floor-standing speakers with large woofers, it is also worth trying out a frequency of 60 Hertz. If, on the other hand, they are small satellites or bookshelf speakers, a setting of 100 Hertz and more may make sense. At this point, it is important to experiment a lot with familiar music and film clips – because only repeated listening will lead to a perfect result.
Modern AV receivers and preamplifiers also have integrated crossovers. This is usually less common with stereo receivers. If a receiver is used in the living room or home theater, it is advisable to set the crossover frequency to the highest frequency.
How do you set the phase on the subwoofer correctly?
A phase control allows the phase to be adjusted continuously within a range of 0 degrees to 180 degrees. It is helpful when the subwoofer and the floor standing loudspeaker are not positioned at the same distance from the listening position. This is because the reproduction of low tones from the subwoofer and the main speakers can cause cancellation in the bass range because the waves neutralize each other. With the phase control it is thus possible to align the sound waves from different sources. This setting is best made by ear from the later reference position.

IWOOFER-APP QUICK START

Note
All screenshots shown are from the iOS version of the app. The apperance and features of the Android version of the app may differ!

1. Navigate to the App Store of your smart device and search for and install the app „woofer“ or „woofer Pro“ by Artery Khlyupin.
2. As long as your VI-Q subwoofer is powered and your smart device‘s Bluetooth is turned on, you will see a seemingly random string of letters and numbers when you open the app, which is best renamed in the app‘s options menu. Select this device. lf you have multiple VI-Q subwoofers, they will all show up here.
   |
   ---|---

Troubleshooting: lf the subwoofer is not receiving an input signal, it will go into standby mode after a while and will not show up on this screen. lf this is the case for you, either unplug the subwoofer and plug it back in, or input an input signal to bring
it out of standby. lf this doesn‘t work, make sure no other smart device is connected to the subwoofer via the woofer-App. Otherwise, try using a different smartphone or tablet.

3. After connecting to the VI-Q subwoofer hardware, you should see the app harness screen as below (room correction is not available if you are not using the Pro-App).

IWOOFER-APP QUICK START
The woofer-app has a rename function in the options menu that allows you to replace the device name and UDID number. This is very helpful when controlling multiple subwoofers at the same time with the same app.
