Their many years of designing and building wireless systems for professionals and touring artists have resulted in the very best audio and rf circuits, and a tradition of careful attention to detail. You will receive many years of superior service from your wireless 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 radio-frequency (rf) signal substitutes for the cable, forming a circuit between the guitar and the amplification system. A wireless system consists of two parts, the transmitter and the receiver. The transmitter sends the audio signal from the microphone to the receiver. An audio cable connects the output of the receiver to amplification system. At any given rf frequency, only one transmitter at a time can be used to send a signal to a receiver of the same frequency. If multiple wireless systems are needed, a separate receiver is required for each individual transmitter. Each wireless system must operate on a different radio-frequency band in order to avoid interference. GS2500 wireless systems operate in the radiofrequency band between 169 and 186 MHz. _OWNER'S MANUAL FEATURES GT1000 BodypackTransmltter • Detachable guitar cable with Tini QG (mini 3-pin XLR) connector and 1/4-inch connector. • 12-dB level control to match pickup outputs. • Separate “power on” and “audio mute” transmitter switches. • 50 milliwatts transmitter output power—the maximum legal limit for the greatest coverage area—and up to 10 hours of operation on a 9-volt alkaline battery. GR2500True-Diversity Receiver • True dual-receiver space diversity system for maximum range and reliability. • 105 dB signal-to-noise ratio for noiseless operation. • Clean, precise and natural sound reproduction using proprietary DNX™ compander circuitry for audio processing. • Ten-segment LED audio VU bargraph display, plus squelch and diversity status indicators on the receiver front panel, for fast and easy setup. • Switchable low and high output level on professional XLR connector, and line output level on standard 1/4-inch phone jack. • Squelch control on rear panel controls receiver sensitivity while maintaining proper balance between channels. • Solidly built, rack-mountable receiver with heavy-duty internal ac power supply, switchable for 115-V or235-V operation and detachable three-prong (grounded) powercable. two EV GS2500 WIRELESS GUITAR SYSTEM OWNER’S MANUAL QUICKSTARTUP PROCEDURE To put your GS2500 wireless system into operation immediately, use the following instructions. Review the detailed information in the remainder of the manual for additional ways to reach optimum performance and sound quality. GR2500 Receiver Setup 1) Attach the whip antennas to the rear-panel antenna connectors, twisting clockwise one-quarter turn to lock (disconnect by lightly pushing in and twisting counterclockwise one-quarter turn) (see Figure 1). Position the antennas in an upright “V" configuration (like TV rabbit ears). If the receiver is mounted in a rack, the whip antennas can be made to go straight back by loosening the Allen screw in the barrel of the BNC connector, pulling the antenna out, replacing it in the top of the BNC connector, and retightening the Allen screw. Note: Dipole antennas provide better range and reliability in difficult installations. See section on antennas later in this manual. 2) Keep the level low or oft on the mixer/ preamp/amplifier channel you will be using for the wireless. 3) Plug the receiver power cable into a standard 120-V ac outlet. If used with other than a 120-V ac outlet, please see section on “Conversion from 115-to 235-Volt Operation." 4) Plug one end of your audio cable (not supplied) into the appropriate output connector (XLR or 1/4-inch) on the rear panel of the receiver (see Figure 2). Plug the other end of the audio cable into the mixer/ preamp/amplifier input. 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. The unbalanced 1/4-inch output is line level only, and the XLR output is switchable low or high level. Do not connect either pin 2 or pin 3 to ground (common) at any time. 5) Depress the POWER switch to turn the receiver on; the green power LED will light. 6) Turn the “AUDIO ADJ” control on the receiver rear panel to the “2:00” 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.
