ENGLISHIntroduction The VR3 receiver provided with the VHF Series wireless system utilizes non-diversity technology, incorporating a single antenna for ease of use and minimal cost. The VR3TD receiver provided with the VHF TD Series system utilizes a patented technological breakthrough called “Microprocessor True Diversity,” whereby a single chassis houses two antennas (called “Antenna A” and “Antenna B”) and a receiver circuit. A built-in computer chip continuously scans RF signals from the two antennas and determines which one has the clearest and strongest reception, automatically (and silently) switching that signal to the receiver. This allows you to maintain the wireless communication link over a much broader area range than would be allowed by a receiver utilizing a single antenna and also virtually eliminates multipath dropouts, interference and phase cancellation problems. In addition, special sample-and-hold linking circuitry ensures that correct phase correlation is maintained at all times, with no noise or pops during antenna switching. The result is performance which exceeds that of conventional antenna true diversity systems and the highest quality audio fidelity available in any wireless system. Finally, the provision of Signetics® noise reduction produces crystal-clear sound with minimized background noise and hiss. In this manual, you’ll find a more detailed description of the features of your VHF TD Series or VHF Series system, as well as a guided tour through all components, step-by- step instructions for setting up and using your system and full specifications. If your VHF TD Series or VHF Series system was purchased in the United States, you’ll also find a warranty card enclosed—don’t forget to fill it out and mail it! This will enable you to receive online technical support and will allow us to send you updated information about other Samson products in the future. If your VHF TD Series or VHF Series system was purchased outside of the United States, contact your local distributor for warranty details.

ENGLISH5 Guided Tour - VR3TD Front Panel 1: Antennas (A and B) - The antenna mountings allow full rotation for optimum placement. In normal operation, both Antenna A (the antenna on the left) and Antenna B (the antenna on the right) should be placed in a vertical position. Both antennas can be folded inward for convenience when transporting the VR3TD. See the “Setting Up and Using Your VHF TD Series / VHF Series System” section on page 10 in this manual for more information about antenna positioning. 2: Volume control - This knob sets the level of the audio signal being output through both the balanced and unbalanced output jacks on the rear panel. Reference level is obtained when the knob is turned fully clockwise. 3: “TX ON” LED - Lights when carrier signal of sufficient strength is being received by the VR3TD. 4: SQL (Squelch) control - This control determines the maximum range of the VR3TD before audio signal dropout. Although it can be adjusted using the supplied plastic screwdriver, it should normally be left at its factory setting. See the “Setting Up and Using Your VHF TD Series / VHF Series System” section on page 10 in this manual for more information. 5: A/B LEDs - When signal is being received, one of these will be lit yellow, showing you whether the (left) “A” or (right) “B” receiver is currently being used. The VR3TD constantly scans its two antennas and automatically selects whichever is receiving the strongest, clearest signal. This Microprocessor True Diversity switching is completely inaudible, but it effectively increases overall range while virtually eliminating potential interference and phase cancellation problems. 6: AF Level meter - This “ladder” display (similar to the VU bar meter used on audio devices) indicates the strength of the incoming audio signal. When the “100%” segment is lit, the incoming signal is optimized at unity gain; when the “125%” segment is lit, the signal is overloading. When only the left-most “10%” segment is lit, the incoming signal is at just 10% of optimum strength. If no segments are lit, little or no signal is being received. See the “Setting Up and Using Your VHF TD Series / VHF Series System” section on page 10 in this manual for more information. 7: Power LED - This lights green whenever the VR3TD is turned on. 8: Power switch - Use this to turn the VR3TD power on and off. When it is on, the Power LED (see #7 above) is lit. 10% 25% 75% 100% 125% MAX.

Series ENGLISH6 Guided Tour - VR3TD Rear Panel 1: DC input - Connect the supplied 12 volt 250 mA power adapter here, using the strain relief as shown in the illustration below. WARNING: The substitution of any other kind of power adapter can cause severe damage to the VR3TD and will void your warranty. 2: Unbalanced output* - Use this unbalanced high impedance (5K Ohm) 1/4" jack when connecting the VR3TD to consumer (-10) audio equipment. Wiring is as follows: tip hot, sleeve ground. 3: Audio Output Level switch - Sets the audio output level attenuation of the balanced output (see #4 below) to -20 dBm (line level) or -40 dBm (mic level). See the “Setting Up and Using Your VHF TD Series / VHF Series System” section on page 10 in this manual for more information. 4: Balanced output* - Use this electronically balanced low impedance (600 Ohm) XLR jack when connecting the VR3TD to professional (+4) audio equipment. Pin wiring is as follows: Pin 1 ground (shield), Pin 2 high (hot), and Pin 3 low (cold).

• If required, both the unbalanced and balanced outputs can be used simultaneously.

Using the strain relief: Gather up a loop of wire and pass it through the strain relief,then pass the adapter plug through the loop in order to create a knot.

The VT3L is supplied witheither a lavalier or headset microphone (connected via a Switchcraft mini-XLR jack), whilethe VT3 is supplied with a permanently connected cable that terminates at a 1/4" plug.A wiring chart showing the connections to popular lavalier and headset microphones canbe found on page 49 of this manual. 2: Battery level meter - This set of three multicolor LEDs indicates relative battery power, indicating whether the installed battery is at low (red), mid (yellow) or high (green)strength. One or more of these will light whenever the VT3L or VT3 is powered on (see#5 on the next page). When all three are lit, the battery is at maximum strength. When only the red “low” indicator lights, RF performance is degraded and the battery needs to be replaced. 3: Audio on-off switch - When set to the “on” position, audio signal is transmitted. When set to the “off” position, the audio signal is muted. Because the carrier signal remains during muting, no “pop” or “thud” will be heard. Note that turning this off does not turn off the transmitter power—it is simply a way to temporarily mute the transmission of audio signal. If you don’t plan on using the transmitter for extended periods, turn off the transmitter power by using the power on-off switch (see #5 on the next page). 4: Battery door release - Press gently inwards on these two indents in order to open the battery door of the VT3L or VT3 and access the Power on-off switch (see #5 on the nextpage) and Gain control (see #6 on the next page).

ENGLISH12 Setting Up and Using Your VHF TD Series/ VHF Series System The basic procedure for setting up and using your VHF TD Series or VHF Series Wireless System takes only a few minutes:

1. For the VHF TD Series / VHF Series system to work correctly, both the receiver and

transmitter must be set to the same channel. Remove all packing materials (save them in case of need for future service) and check to make sure that the supplied receiver and transmitter are set to the same channel. If these channels do not match, contact your distributor or, if purchased in the United States, Samson Technical Support at 1-800-372-6766.

2. Physically place the receiver where it will be used (the general rule of thumb is to

maintain “line of sight” between the receiver and transmitter so that the person using or wearing the transmitter can see the receiver). An optional rack-mount kit (available from your Samson dealer) allows the VR3TD or VR3 to be mounted in a standard 19" rack if desired. Extend the antenna or antennas and place them in a vertical position.

3. Make sure the Power on-off switch in your VT3L / VT3 belt-pack or VH3 handheld

transmitter is set to “Off.” 4a. If your system contains a VT3L or VT3 belt-pack transmitter, press gently inwards on both battery cover release indents to open the battery door. Note that this door is hinged and not intended to be removed from the transmitter case. Please use care when opening this door as undue force will destroy the hinge. 4b. If your system contains a VH3 handheld transmitter, unscrew the bottom section of the microphone by turning it counterclockwise and then slide it off.

5. Place a fresh 9-volt alkaline battery in the transmitter battery holder, taking care to

observe the polarity markings. If you are using a VT3L or VT3 belt-pack transmitter, gen- tly replace the battery door by swinging it up and pressing until it clicks. If you are using a SH4 handheld transmitter, replace the bottom section of the microphone by sliding it on and then screwing it back on. Whichever transmitter you are using, leave it off for the moment.

6. Make the physical cable connection between the VR3TD or VR3 output jack and the

line or mic level audio input of your amplifier or mixer. If you are using the balanced XLR jack (preferable, since it will deliver an electromagnetically cleaner signal), be sure to set the receiver rear panel Audio Output Level switch correctly. If required, both the balanced and unbalanced outputs can be used simultaneously. Leave your amplifier (and/or mixer) off at this time.

7. Turn the Volume knob on the VR3TD or VR3 completely counterclockwise. Using the

strain relief, connect the supplied AC adapter to the DC Input on the rear panel of the VR3TD or VR3, then plug the adapter into any standard AC outlet. Press the front panel Power switch to turn on the VR3TD or VR3; the green “Power” LED will light up, but all other front panel LEDs will remain unlit.

8. Turn on the power to the VT3L, VT3 or VH3 transmitter (using its Power on-off switch);

all three Battery strength LEDs will light if the battery is sufficiently strong. At this point, the “TX” LED on the front panel of the receiver will light. If you are using an VR3TD receiver, either the “A” or “B” yellow LED on the front panel will also light, depending upon which antenna is receiving the stronger signal. ENGLISH13 Setting Up and Using Your VHF TD Series/ VHF Series System

9. Now it’s time to set the audio levels. Turn on your connected amplifier and/or mixer but

keep its volume all the way down. Next, make sure that your transmitter is unmuted by setting its Audio switch to “On.” Then set the Volume knob on the VR3TD or VR3 fully counterclockwise. If you are using the VH3 transmitter or if you are using the VT3L transmitter with a connected lavalier microphone or headset, speak or sing into the mic at a normal performance level while observing the VR3TD or VR3 front panel AF Level meter. If you are using the VT3 transmitter with a connected instrument, play the instrument at normal performance level while observing the VR3TD or VR3 front panel AF Level meter. If the “100%” (unity gain) segment is lighting steadily, with just occasional higher excursions, the audio level is correctly set. If not, use the supplied plastic screwdriver to slowly adjust the VH3, VT3L, or VT3 Gain control (trimpot) until the VR3TD or VR3 AF Level meter “100%” (unity gain) segment lights steadily (with occasional higher excur- sions). Then slowly raise the VR3TD or VR3 Volume knob to the 2 o’clock position (unity gain) and, finally, set the volume of your amplifier/mixer until the desired level is reached. If you are using a VT3L beltpack transmitter equipped with a lavalier microphone, note that correct lavalier placement is critical to sound quality. We recommend that you place it as shown in the illustration on the right—as close to your mouth as possible but off to one side (to minimize nasality) and unobstructed by clothing. Bear in mind also that omni microphones (mics which pick up signal from all directions) are more prone to feedback problems than unidirectional (cardioid or supercardioid) ones; in general, you can avoid feedback by taking care not to use any microphone directly in front of a PA speaker (if this is unavoidable, try using an equalizer to attenuate those high- or mid-range frequencies which are causing the feedback “squealing”).

10. If you hear distortion at the desired volume level (or if the “125%” segment LED in the

AF Level meter is lighting frequently), first check that the VR3TD or VR3 rear panel Audio Output Level switch is set correctly. Next, make sure that the gain structure of your audio system is correctly set (consult the owners manual of your mixer and/or amplifier for details). If you still hear distortion, do the following:

• If you are using a VH3 handheld transmitter or an VT3L transmitter with connected lavalier microphone or headset, its Gain control has been factory preset to provide optimum level for the particular microphone model being used and so no adjustment should be necessary. Any distortion present should therefore simply be a matter of the microphone being too close to the mouth; try moving it further away. If this does not solve the problem, use the supplied plastic screwdriver to turn the Gain control (trimpot) on the VH3 or VT3L slowly counterclockwise until the distortion disappears.

• If you are using a VT3 transmitter with an instrument such as electric guitar or bass, lower the output level of the instrument until the distortion disappears. Alternatively, you can use the supplied plastic screwdriver to turn the Gain control (trimpot) on the VT3 slowly counterclockwise until the distortion disappears. Note that, following this setup procedure, you can always lower the Volume knob of the VR3TD or VR3 in order to further attenuate the output signal if necessary. INPUT SAMSON

11. Conversely, if you hear a weak, noisy signal at the desired volume level (and with the

Volume control of the receiver turned fully clockwise), again make sure that the VR3TD or VR3 rear panel Audio Output Level switch is set correctly and that the gain structure of your audio system is correctly set. If it is and the signal coming from the VR3TD or VR3 is still weak and/or noisy, do the following:

• If you are using a VH3 transmitter or an VT3L transmitter with connected lavalier microphone or headset, its Gain control has been factory preset to provide optimum level for the particular microphone model being used and so no adjustment should be necessary. Any weakness of signal should therefore simply be a matter of the microphone being too far from the mouth; try moving it closer. If this does not solve the problem, use the supplied plastic screwdriver to turn the Gain control (trimpot) on the VH3 or VT3L slowly clockwise until the signal reaches an acceptable level.

• If you are using a VT3 transmitter with an instrument such as electric guitar or bass, raise the output level of the instrument until a good signal is achieved. Alternatively, you can use the supplied plastic screwdriver to turn the Gain control (trimpot) on the VT3 slowly clockwise until the signal reaches an acceptable level.

12. Temporarily turn down the level of your mixer/amplifier system and turn off the power

to your transmitter, leaving the VR3TD or VR3 on. Then restore the previously set level of your mixer/amplifier. With the transmitter off, the receiver output should be totally silent—if it is, skip ahead to the next step. If it isn’t (that is, if you hear some noise), you may need to adjust the receiver’s front panel Squelch control. When the Squelch control is at its minimum setting, the VHF TD Series / VHF Series system always provides maximum range without dropout; however, depending upon the particular environment your system is used in, you may need to reduce that range somewhat in order to eliminate band noise or interference when the transmitter is turned off. To do so, use the provided screwdriver to rotate the Squelch control completely counterclockwise (to the “Min” position), then slowly turn it clockwise until the noise disappears. If no noise is present at any position, leave it at its fully counterclockwise “Min” position (so as to have the greatest overall range available).

13. When first setting up the VHF TD Series or VHF Series System in a new environment,
