This equip-ment generates, uses, and can radiate radio frequen-cy energy and, if not installed and used in accordancewith the instruction manual, may cause harmful inter-ference to radio communications.However, there is no guarantee that interference willnot occur in a particular installation. If this equipmentdoes cause harmful interference to radio or televisionreception, which can be determined by turning theequipment off and on, the user is encouraged to try tocorrect the interference by one or more of the follow-ing measures.a) Reorient or relocate the receiving antenna.b) Increase the separation between the equipmentand receiver.c) Connect the equipment into an outlet on a circuitdifferent from that to which the receiver is connect- ed. d) Consult the dealer or an experienced radio/TVtechnician for help.CAUTIONChanges or modifications to this equipment notexpressly approved by TEAC CORPORATION forcompliance could void the user’s authority to operatethis equipment.For U.S.A.TASCAM VL-A's 3

1 Read these instructions. 2 Keep these instructions. 3 Heed all warnings. 4 Follow all instructions. 5 Do not use this apparatus near water. 6 Clean only with dry cloth. 7 Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions. 8 Do not install near any heat sources such as radi- ators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. 9 Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A ground- ing type plug has two blades and a third ground- ing prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. 10 Protect the power cord from being walked on or pinched particularly at plugs, convenience recep- tacles, and the point where they exit from the apparatus. 11 Only use attachments/accessories specified by the manufacturer. 12 Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. 13 Unplug this apparatus during lightning storms or when unused for long periods of time. 14 Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

• Do not expose this apparatus to drips or splashes.

• Do not place any objects filled with liquids, such as vases, on the apparatus.

• Do not install this apparatus in a confined space such as a book case or similar unit.

• The apparatus draws nominal non-operating power from the AC outlet with its POWER switch in the off position.

• The apparatus should be located close enough to the AC outlet so that you can easily grasp the power cord plug at any time.

• An apparatus with Class I construction shall be connected to an AC outlet with a protective grounding connection.

• Excessive sound pressure from earphones and headphones can cause hearing loss.

• The apparatus draws nominal non-operating power from the AC outlet with its STANDBY/ON in the Standby position.4 TASCAM VL-A's

ENGLISH 1-INTRODUCTION Environmental Precautions A speaker unit can be used in most places, but to maintaintop performance and prolong operating life, do not place itin the following locations.– On an unsteady surface, or where there is frequent vibra-tion or resonance– Near a window or where it can be exposed to direct sun-light– Near heating or air conditioning vents, or in very hot orcold places– Places with high humidity or poor ventilation Product Care Wipe off any dirt or dust with a dry, soft cloth. Do not wipewith a chemical cleaning cloth, benzene, paint thinner oralcohol. This can damage the surface of the product.6 TASCAM VL-A's

ENGLISH Installation The speaker placement is important to monitor correctsound.To get best performance of the speaker system, please fol-low the instruction explained below. Installing the VL-A’s 1.The unit should be placed at least 60 cm (100 cm recom-mended) away from obstacle to the rear and at least 40 cm(60 cm recommended) from any obstacle on either side.

2. Basically, two units and the listener should align to form

a regular triangle.3. The height of units, more precisely, the top of the woofershould come up to where your ears are in normal listen-ing environment.

2-CONNECTION AND INSTALLATION

Precautions for Connection – When unpacking, do not grab by the front of the unitwhere the drivers are mounted as this may result in dam-age to the cone.– Turn off the power switch on the rear panel before con-necting the power cord to the unit.– Be sure that the connection is made securely to avoidaccidental disconnection.– Adjust the input signal levels on your audio device to theminimum or zero before turning on the power on the rearpanel to prevent possible damage to the unit.– Do not use the system continuously for long periods oftime at high volume levels to avoid any possible damageto your hearing.– Depending on the TV monitor used with the system, thespeaker system may affect the quality of the picture onthe monitor. In this case, try various positions to findbest 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 unitshould match the pin assignments explained in“Connection.” Connection 1. Turn off the power switch.2. Connect the supplied power cord to the main unit andmake sure the plug is inserted completely to prevent itfrom coming off. Connect the other end of the powercord to an AC outlet.3.Connect the XLR balanced cable or TRS cable to youraudio system to send audio signals. The pin assignments ofthe XLR balanced cable are shown below.1: Ground, 2: Hot, 3: ColdThe pin assignments of the TRS balanced cable areshown below.Tip: Hot, Ring: Cold, Sleeve: GroundTASCAM VL-A's 7

4. Placing the unit vertically is recommended. If you placethe unit horizontally, refer to the diagram below.

Installing a Subwoofer Adding a subwoofer to the monitor system lets you enjoyrich bass sounds.The optimum placement of the subwoofer varies accordingto the placement of the other speakers and the room envi-ronment. The following section explains one of the ways to place thesubwoofer. Surround Setup This shows the subwoofer placed at the same distancefrom the listening position as the other speakers.The example is the placement of the 5.1 channel surroundmonitor system.This setup is recommended by ITU, InternationalTelecommunications Union, according to ITU-R BS.775-2“Multichannel stereophonic sound system with and with-out accompanying picture.”DO NOT place any obstacles that may block the flow ofair, which is medium of the sound, or create reflectedsound, especially, the material of high reflection tendencyincluding glass, mirror or metal. Place those materialsaway from the path of the sound from VL-A’s. NOTE Tweeter Output Unit Protective Function (VL-A5/VL-A8) The VL-A5 and VL-A8 tweeter output units use a tempera-ture-sensitive polymer switch as a protective device againstexcessively high output.Once this protective function has been activated, the tweet-er output will be muted until the temperature of the polymerswitch returns to normal.When treble sounds (output from the tweeter speaker) cannot be heard, turn off the power and wait two to three min-utes before turning on the power again. Check if the treblesound is output from the speaker.8 TASCAM VL-A's
