Performance Guide

Aim at the characteristic of ear, to care and prevent your ear and equipment, the normal sound pressure level of headphone is 90dB in a colsing circumstance. Hereinafter, the divisiory datum for user reference---on maximum time exposure to sound pressure levels before hearing damage occurs.

3.position the rack-mount brackets over the holes into the sides of each receiver.

4.Secure the brackets to the receivers with the supplied screws

5.Slide the linked receivers into a 19-inch audio equipment rack.

6.Secure the brackets to the rack using the supplied screws.

90 dB SPL at 8 Hours 95 dB SPL at 4 Hours 100 dB SPL at 2 Hours 105 dB SPL at 1 Hours 110 dB SPL at 30 Minutes 115 dB SPL at 15 Minutes 120 dB SPL -----Damage may occur

4. Mix Mode Application

Counterclockwise Mid-Point Clockwise

1. Receiver receives two signals from the transmitter

Channel 1

3. The receiver sends the mixed signal to both headphones.

Channel 2

2. Using the balance knob, the user blends the two signals until the correct mix is achieved.

4. The user may continue

1.2 Transmitter Setting

1) Frequency Setting: Short press set button to e nter s etting s tate; T hen s hort press MENU setting b utton u ntil th ed isplay o f fr equency/channel is fl ashing. Short press o r settin g butto na t on e blow , th e frequency/channel will turn up/down a level. Length press or setting button, the frequency/channel will turn up /down continuously.

3. Mix Mode/Stereo Control

The receiver receives two signals (1/L and 2/R) from transmitter, then processes these signals in either mix mode or stereo:

Stereo: In stereo, the signals remian separate so tha t 1/L i s hear d throug hth e left headphone and 2/R is heard through the right headphone. The balance knob on receiver to adjusts the balance between the left and right headphones.

Mix Mode: In mix m ode, t he s ignals a re mixed in re lation to o ne a nother u sing

the balanced into one signal . The on e mixe d signa l is se nt to bo th t he l eft a nd
