Environmental Precautions

A speaker unit can be used in most places, but to maintain top performance and prolong operating life, do not place it in the following locations.

• On an unsteady surface, or where there is frequent vibration or resonance
• Near a window or where it can be exposed to direct sunlight
• Near heating or air conditioning vents, or in very hot or cold places
• Places with high humidity or poor ventilation

Product Care

Wipe off any dirt or dust with a dry, soft cloth. Do not wipe with a chemical cleaning cloth, benzene, paint thinner or alcohol. This can damage the surface of the product.

Precautions for Connection

• When unpacking, do not grab by the front of the unit where the drivers are mounted as this may result in damage to the cone.
• Turn off the power switch on the rear panel before connecting the power cord to the unit.
• Be sure that the connection is made securely to avoid accidental disconnection.
• Adjust the input signal levels on your audio device to the minimum or zero before turning on the power on the rear panel to prevent possible damage to the unit.
• Do not use the system continuously for long periods of time at high volume levels to avoid any possible damage to your hearing.
• Depending on the TV monitor used with the system, the speaker system may affect the quality of the picture on the monitor. In this case, try various positions to find best place to install the speaker system.
• The voltage supplied to the unit should match the voltage as printed on the rear panel.
• Use audio cables that are free of damage.
• Do not send signals other than audio signals to the unit.
  The polarity of an audio cable connected to the unit should match the pin assignments explained in "Connection."

Connection

1. Turn off the power switch.
2. Connect the supplied power cord to the main unit and make sure the plug is inserted completely to prevent it from coming off. Connect the other end of the power cord to an AC outlet.
3. Connect the XLR balanced cable or TRS cable to your audio system to send audio signals. The pin assignments of the XLR balanced cable are shown below.

1: Ground, 2: Hot, 3: Cold

The pin assignments of the TRS balanced cable are shown below.

Tip: Hot, Ring: Cold, Sleeve: Ground

Installation

The speaker placement is important to monitor correct sound.

To get best performance of the speaker system, please follow the instruction explained below.

Installing the VL-A's

1. The unit should be placed at least 60~cm (100 cm recommended) away from obstacle to the rear and at least 40 cm (60 cm recommended) from any obstacle on either side.

1. Basically, two units and the listener should align to form a regular triangle.

1. The height of units, more precisely, the top of the woofer should come up to where your ears are in normal listening environment.

1. Placing the unit vertically is recommended. If you place the unit horizontally, refer to the diagram below.

Installing a Subwoofer

Adding a subwoofer to the monitor system lets you enjoy rich bass sounds.

The optimum placement of the subwoofer varies according to the placement of the other speakers and the room environment.

The following section explains one of the ways to place the subwoofer.

Surround Setup

This shows the subwoofer placed at the same distance from the listening position as the other speakers.

The example is the placement of the 5.1 channel surround monitor system.

L:Main Front Lch Speaker
R:Main Front Rch Speaker
C:Center Speaker
LS: Left Surround Speaker
RS:Right Surround Speaker

NOTE

This setup is recommended by ITU, International Telecommunications Union, according to ITU-R BS.775-2 "Multichannel stereophonic sound system with and without accompanying picture."

DO NOT place any obstacles that may block the flow of air, which is medium of the sound, or create reflected sound, especially, the material of high reflection tendency including glass, mirror or metal. Place those materials away from the path of the sound from VL-A's.

Tweeter Output Unit Protective Function (VL-A5/VL-A8)

The VL-A5 and VL-A8 tweeter output units use a temperature-sensitive polymer switch as a protective device against excessively high output.

Once this protective function has been activated, the tweet-er output will be muted until the temperature of the polymer switch returns to normal.

When treble sounds (output from the tweeter speaker) can not be heard, turn off the power and wait two to three minutes before turning on the power again. Check if the treble sound is output from the speaker.

3-NAMES AND FUNCTIONS

VL-A4 Rear Panel Front Panel

VL-A5 Rear Panel Front Panel

VL-A8 Rear Panel Front Panel

① ~ IN jack

This IN jack is used to connect the supplied power cord.

② FUSE holder

This unit is equipped with a fuse. If the unit does not work, disconnect the power plug from the AC outlet and then contact the nearest qualified service personnel.

This is used to turn the power on and off.

④ INPUT jack

This is a balanced input terminal that uses an XLR balanced cable and TRS PHONE balanced cable combination jack. This INPUT jack connects the unit to an external device.

LEVEL CONTROL knob

This is used to adjust the output volume.

⑥ POWER indicator (Front Panel/Rear Panel)

This indicator lights up when the power switch is turned on and AC power is supplied to the IN jack.

HF CONT switch (VL-A5, VL-A8 only)

This is used to adjust the treble level.

+1.5 dB 8k: Boosts the 8 kHz frequency by 1.5 dB.
+1.5 dB 3k: Boosts the 3 kHz frequency by 1.5 dB.
-1.5 dB 8k: Cuts the 8kHz frequency by 1.5 dB.
-1.5 dB 3k: Cuts the 3kHz frequency by 1.5 dB.

LF CONT switch (VL-A5, VL-A8 only)

This is used to adjust the bass level.

LF+ Boosts the 150Hz or 800Hz frequency by 1.5 dB.

LF-: Cuts the 150Hz or 800Hz frequency by 1.5 dB.

LF CUT: Cuts bass sounds at a frequency of 500Hz or lower.

LF-S8 Rear Panel Front Panel

① POWER switch

This is used to turn the power on and off.

② FUSE holder

This unit is equipped with a fuse. If the unit does not work, disconnect the power plug from the AC outlet and then contact the nearest qualified service personnel.

③ ~IN jack

This IN jack is used to connect the supplied power cord.

④ INPUT CH1/CH2 JACKS

These balanced input jacks suit for both XLR balanced and TRS PHONE balanced connectors, and are typically connected to output jacks on a mixer.

CROSS FREQ knob

This control is used to set a cutoff frequency between 40 to 120Hz to cut high or low frequency output from the subwoofer.

⑥ OUTPUT CH1/CH2 JACKS

These output jacks connect XLR balanced connectors. High frequency signals are output through the jack (low-frequency is cut according to the cutoff frequency set with the CROSS FREQ knob). An external device such as a power amplifier is connected to the jack.

When you use the LF-S8 with the VL-A4, VL-A5 or VL-A8, connect both the left (CH1) and right (CH2) INPUT jacks.

⑦ OUTPUT SUB LF jack

This output jack connects XLR balanced connector. Low frequency signals are output through the jack (high frequency is cut according to the cutoff frequency set with the CROSS FREQ knob). The second subwoofer is connected to this jack.

LEVEL CONTROL knob

This is used to adjust the output level of the subwoofer speaker.

⑨ PHASE switch (0^ / 180^)

This is used to switch the output phase of the subwoofer speaker. Depending on speaker placement, or the combination of speaker systems, bass sounds may be heard differently. If so, try to adjust the output phase using this switch to make bass sounds better for you.

10 POWER indicator

This indicator lights up when the power switch is turned on and AC power is supplied to the IN jack.
