The transmitter and receiver were fine-tuned together as a system to ensure perfect compatibility. Each system is individually hand-tested and walk-tested for reliability and range prior to shipment. To assure field reliability, each receiver is "burned in" for 24 hours in a specially designed environmental chamber, which simulates the heat and ventilation conditions that would be found in a rack of live electronics and power amps. Both transmitters and receivers are shock-tested to detect and prevent any loose connections or parts in the finished system. You will receive many years of superior service from your wireless guitar system, and a new-found freedom now that your movements are no longer limited by a cable. Enjoy the experience. Thank you for your purchase. WHAT IS A WIRELESS SYSTEM? In a wireless system, a radlo-frequency (RF) signal substitutes for the cable, forming a circuit between the instrument and the amplification system. The wireless system consists of two parts, the transmitter and the receiver. The transmitter sends the audio signal from the guitar (or from a microphone, in the case of a wireless microphone system) to the receiver. An audio cable connects the output of the receiver to the amplification system. Only one transmitter can work with one receiver. If multiple wireless guitar or microphone systems are needed, a separate receiver is required for each individual transmitter. Each wireless system must operate on a different radio frequency, to avoid interference. GS-1000 wireless systems operate in the radio-frequency band between 169 and 186 MHz. This frequency range avoids the interference and dropout problems that wireless systems operating on other frequencies have had in the past. FEATURES • Clean, crisp, natural sound, with advanced DNX "B" 2:1 compander audio processing. • Quiet VHF high-band operating frequencies for ultimate range, reliability, and overall system audio quality. • True dual-receiver space diversity system for maximum range and reliability. • 50 milliwatts transmitter output power—maximum legal limit for the greatest coverage area. • Up to 10 hours of transmitter operation on a single standard 9-volt alkaline battery. • Separate "POWER ON" and "AUDIO MUTE" transmitter switches for critical "live" applications. • Ten-segment LED audio VU bargraph display, plus squelch and diversity status indicators on receiver front panel, for fast and easy setup. • Switchable mic and line output level on professional XLR connector, and line output level on standard 1/4-inch phone jack. • Solidly built rack-mountable receiver with heavy-duty built-in AC power supply (UL listed, of course). • 100% made with pride in the USA-backed by a company committed to your success. two EV GS-1000 WIRELESS GUITAR SYSTEM OWNER'S MANUAL QUICK STARTUP PROCEDURE To put your GS-1000 wireless guitar system into operation immediately, use the following instructions. However, for optimum performance and sound quality, review the detailed information later in this manual. 1) If necessary, convert the whip antennas to the right-angle configuration, using the miniature wrench supplied, as shown in the whip-antenna information sheet included. 2) Plug the whip antennas into the rear-panel "ANTENNA" connectors of the receiver (see Figure 1). Position the antennas in an upright "V" configuration (like TV "rabbit ears"). (Dipole antennas provide better range and reliability in difficult installations. See section on antennas later in this manual.) 3) Keep level low or off on the mixer/preamp/instrument amplifier channel. 4) Plug one end of youraudio cable (not supplied) into the appropriate output connector on the rear panel of the receiver (see Figure 2). The receiver XLR output is balanced; for single-ended (unbalanced) applications, use only pins 1 (common) and 2 (signal high). The output level in this mode will be 6 dB less than for the balanced mode. Do not connect either pin 2 orpin 3 to ground (common) at any time. The quarter-inch output is line level only, and the XLR output is switchable mic/line. Plug the other end of the audio cable into the mixer/preamp/instrument amplifier input. If the cable from the XLR output is connected directly into an instrument amp input, set the "MIC/LINE" switch on the receiver rear panel to "UNE". 5) Plug the receiver power cable into a standard 120-Vac outlet. 6) Turn "ON" the POWER switch on the front panel of the receiver, by pushing the switch to the right. The power LED should illuminate. 7) With the provided screwdriver, turn the "AUDIO ADJ" control on the receiver rear panel to the "12 o’clock" (vertical) position (see Figure 3). Begin with the control in this position; after you have adjusted the transmitter level, you may need to readjust the "AUDIO ADJ" control. 8) Slide the cover of the transmitter battery compartment in either direction, until it is completely off.
