Introduction

The ATR7000 Series Wireless Systems from Audio-Technica are small, portable, and adaptable systems created to deliver dependable performance, simple setup, and clear, natural sound quality. The ATR7000 Series Wireless Systems are single-channel, fixed-frequency devices that come in hand-held, head-worn, guitar, and lavalier formats. They are also available in three VHF frequencies (T2: 169. 505 MHz, T3: 170. 245 MHz, T8: 171. 905). The ATW-R7000 receiver, along with either a body-pack transmitter or a portable microphone/transmitter, are included with each 7000 Series Wireless System.

A single-channel, non-diversity receiver with a quarter-wave telescoping antenna and an increased operational range of up to 300 feet is the ATW-R7000. In addition to having indicator lights for power, RF, and AF Peak, the ATW-R7000 also has a volume control. With the accompanying vertical mount, it may be set up either horizontally or vertically. Both the body pack transmitter and the handheld transmitter have an easy-to-reach on/off/standby button; the body pack also has an external microphone volume control and a practical 3. input of 5 mm.

INSTALLATION AND OPERATION

Audio-Technica’s ATR7000 Series Wireless Systems are compact, portable, versatile systems designed to provide reliable performance, easy setup and clear, natural sound quality. Available in handheld, headworn, guitar, and lavalier configurations, the ATR7000 Series Wireless Systems are single- channel, fixed-frequency systems available in three VHF frequencies (169.505, 170.245, and 171.905 MHz).

Each ATR7000 Series Wireless System includes the ATR-R7000 receiver and either a body-pack transmitter or handheld microphone/transmitter. The ATR-R7000 is a non-diversity, single- channel receiver with a quarter-wave telescoping antenna for extended operating range of up to 200 feet. The ATR-R7000 receiver also offers volume control along with Power, RF and AF Peak indicator lights. It can be placed horizontally or vertically with the included stand mount.

Both the body-pack and handheld transmitters use internal 9-volt batteries and have Off/Standby/ On switches. The body-pack transmitter also offers a volume control.

RECEIVER INSTALLATION

LOCATION

For best operation the receiver should be at least 3′ (1 m) above the ground and at least 3′

(1 m) away from a wall or metal surface to minimize reflections. Keep the receiver antenna away from noise sources such as digital equipment, motors, automobiles and neon lights, as well

as large metal objects. In multi-channel systems, position receivers at least 3′ (1 m) apart and keep operating transmitters at least 6′ (2 m) from the receivers to help assure maximum RF performance.

OUTPUT CONNECTION

The receiver provides unbalanced, aux-level output from a ¼” TS (“mono”) phone jack; an output cable is included. Use this shielded audio cable with ¼” phone plug to connect the receiver’s Audio Out jack to the mixer/amplifier’s aux- level input.

POWER CONNECTION

Connect the DC plug on the included AC power adapter to the DC power input on the back of the receiver. Then plug the adapter into a standard 120 Volt 60 Hz AC power outlet.

ANTENNA

The receiver is equipped with a quarter-wave telescoping antenna for extended operating range of up to 200 feet. The quarter-wave telescoping antenna offers extended operating range of up to 200 feet. Position the fully extended antenna in a vertical position for best operating performance.

Be certain to extend the antenna to its full 15″ (39 cm) length by holding it at its base and pulling out on its cap. The antenna may be swiveled 180° in a single plate to achieve vertical position depending upon position of the receiver, but do not attempt to rotate it in a screwing/ unscrewing motion. To do so may damage the antenna and/or receiver. For best performance, locate the receiver so its antenna is in direct line-of-sight to the transmitter’s likely operating position.

MOUNTING INSTRUCTIONS

The receiver features versatile positioning for horizontal or vertical applications. For a horizontal application, place the receiver on a horizontal surface (rubber feet on bottom).

For a vertical mounting position, use the included stand mount. The stand mount snaps into receptacles on the right side of the receiver. Simply insert the stand mount pegs into the receptacles and slide gently into place until locked. Reverse the motion to remove the stand mount.

TRANSMITTER SETUP CONTROLS AND FUNCTIONS

BATTERY SELECTION AND INSTALLATION

An alkaline 9-volt battery is recommended. Make certain the transmitter power switch is Off before installing or changing batteries. When inserting the battery, observe correct polarity as marked inside the battery compartment. The transmitter housings are designed to prevent incorrect installation of the battery; do not force the battery in. Reversed batteries may cause damage to the transmitter.

BODY-PACK TRANSMITTER BATTERY INSTALLATION

1. Slide off the battery cover as shown in Figure D.
2. Carefully insert a fresh 9V alkaline battery, observing polarity markings.
3. Replace the battery cover.

HANDHELD TRANSMITTER BATTERY INSTALLATION

1. While holding the upper part of the transmitter body just below the ball-screen, unscrew the lower body cover and slide it downward to expose the battery compartment (Fig. E).
2. Carefully insert a fresh 9V alkaline battery, observing polarity markings.
3. Screw the body back together. Do not overtighten.

BATTERY CONDITION INDICATOR

The red battery condition indicator (Fig. D/E) should light strongly with a fresh battery. As the battery weakens, the indicator will grow dimmer. When the indicator becomes very dim or goes out, there is little life left in the battery. Replace it at once for continued operation of the transmitter.

BODY-PACK TRANSMITTER INPUT CONNECTION

Connect an audio input device (included lavalier microphone, guitar cable or headworn microphone) to the input connector on the top of the transmitter. This is a screw-down locking connector. To lock the connector to the transmitter, screw the silver locking ring on the threaded portion of the input connector clockwise. To remove the connector, unscrew the silver locking ring counterclockwise, and then simply pull up on the connector’s metal collar.

TRANSMITTING ANTENNA

The body-pack transmitter uses the attached mic/guitar cable as the antenna. Due to this feature, any modification of the cable length or connector termination will affect the performance. If the received signal is marginal, experiment with different transmitter positions on your body or instrument or try repositioning the receiver.

SYSTEM OPERATION

Turn down the receiver volume control and the mixer/amplifier level before starting up the wireless system. Do not switch on the transmitter yet.

RECEIVER ON…

Plug the power supply into an AC power source. Turn on the rotary On/Off/Volume control. The red power indicator on the front panel will light.

TRANSMITTER ON…

When the transmitter is switched on, the receiver’s green RF signal indicator will light. The transmitters have a 3-position power switch. When the switch is set to “Standby” (ST or ST.BY), the transmitter produces RF with no audio signal. When the switch is “On,” the transmitter produces both RF and audio. Excessive audio input to the transmitter will cause the receiver’s red AF Peak indicator to light.

RECEIVER VOLUME

Under typical operating conditions, the receiver’s volume control should be turned all the way up, with overall system audio gain adjusted at the mixer or amplifier

TEN TIPS TO OBTAIN THE BEST RESULTS

1. Use only fresh alkaline batteries. Do not use “general purpose” (carbon-zinc) batteries.
2. Position the receiver so that it has the fewest possible obstructions between it and the normal location of the transmitter. Line-of-sight is best.
3. The transmitter and the receiver should be as close together as conveniently possible.
4. If receiver signal is weak, try mounting it in the vertical position for improved reception.
5. Do not place the receiver antenna within 3′ (1 m) of another receiver or antenna.
6. The receiver antenna should be kept away from any metal.
7. A receiver cannot receive signals from two transmitters at the same time.
8. If the receiver output is set too low, the overall signal-to-noise ratio of the system may be reduced. Conversely, if the volume control of the receiver is set too high, it may over-drive the input of the mixer/amplifier, causing distortion. Adjust the output level of the receiver so the highest sound pressure level going into the microphone (or the loudest instrument playing level) causes no input overload in the mixer, and yet permits the mixer level controls to operate in their “normal” range (not set too high or too low). This provides the optimum signal-to-noise for the entire system.
9. Turn the transmitter and receiver off when not in use. Remove the battery if the transmitter is not to be used for a period of time.
10. Make sure to screw down the locking ring on the guitar and microphone cables for a secure connection.

SYSTEM OPERATING FREQUENCIES

Systems on these frequencies may be combined for up to three simultaneous operating channels.

FREQUENCY SELECTION

Each transmitter/receiver system operates on a single factory aligned, crystal-controlled frequency. Available frequencies are shown in the chart on page 7.

Operating frequency is specified by a two character code, such as “T2,” in addition to the actual frequency in MHz The frequency of each transmitter appears on a label on the outside/back of the unit. The frequency of each receiver appears on a label on the bottom panel of the unit. On the body-pack the transmitter is located outside on the back. The handheld label is located inside the back of the battery compartment. The frequency of each system appears on the outer carton.

FAQs

How does a portable microphone function?****

The microphone has a portable transmitter embedded into its body. Due to this, the microphone is slightly bigger than a conventional corded one. Transforming audio signals into radio signals is the transmitter’s responsibility.

Can I record using a wireless microphone?****

Without the use of a cable between the microphone and camera, we can record high-quality voice and video simultaneously by employing a wireless microphone.

What is necessary for a wireless mic to function?****

The wireless microphone signal cannot be sent properly unless the transmitter and receiver are tuned to the same radio frequency.

Can many wireless mics be used simultaneously?****

No, it won’t work like that. One active microphone transmitter at a time can only have its signal demodulated by a wireless receiver. However, as long as only one transmitter is turned on at any given time, you are free to utilize either one.

How long do wireless microphone batteries last?****

Most wireless lavalier mics run 5 to 10 hours on a single charge when using an AA battery.

Can microphones function without electricity?****

Some microphones (active mics) require power to operate, while others do not (passive mics). Power is needed for microphones with integrated active electronics or non-electret electrostatic (condenser) capsules. Powered dynamic microphones are those that lack an inbuilt preamp.

Does a wireless microphone require a speaker to function?****

A microphone can be used without any speakers, headphones, or other playback devices.

Can I use my phone with a wireless microphone?****

Your smartphone can connect to any wireless microphone system as long as the receiver output is a 3.5mm connector.

How much energy is consumed by a wireless microphone?****

In contrast to wireless microphone systems, which typically have an output power of only 50 mW (fifty one thousandths of one watt! ), television transmitters can operate at power levels up to one million watts.

When is a wireless microphone appropriate to use?****

A wireless microphone can be defined as a recording device that uses radio waves to transmit and receive sound. Without any wires, it operates wirelessly.

Do wireless microphones require batteries?****

The power for all wireless microphone transmitters (and some receivers*) comes from batteries. Batteries come in a wide variety, from conventional alkaline batteries to numerous rechargeable battery types, but they don’t always offer the same degree of service.

How crucial is microphone quality?****

The highest sound quality is achieved when using a top-notch microphone, whether you are recording in a studio or doing a live interview on location. Poor audio is frequently the result of a microphone or recording device of low quality.

A wireless microphone can broadcast how far?****

The typical range for systems of the kind detailed here (10-50 mW, VHF or UHF) can range from 100 feet to 1000 feet.

Why do wireless microphones suddenly stop working?****

A transmitted wave contacts surfaces that either reflect or absorb certain portions of the wave as it propagates. These waves cause dropouts and dead spots for wireless microphones because they arrive at the receiver at the receiver at slightly different times and are therefore out of phase.

What does the three to one rule mean in terms of microphones?****

This rule focuses on reducing the audible phasing issues that can occur when converting many microphones to mono.
