Page 1 Users Manual Electro-Voice Model REV-H Handheld Wireless Microphone Transmitter The Electro-Voice (Ev) REV-H is a Professional Grade Wireless Handheld Transmitter operating in the UHF frequency range. The REV-H combines frequency agility and ease of use like no other. The transmitter operates within a 24 MHz wide segment in 25 KHz steps. The high quality audio circuitry and advanced Radio Frequency (RF) signal processing offer broadcast quality signal-to-noise and audio clarity. The typical line-of-sight distances for the system may be up to 300 feet. System features include:  Durable Painted Metal Handle.  Permanent Flash Memory for frequency/setting storage.  On-Loc prevents accidental power off (when set).  LCD Display with Backlight for ease of viewing.  Internal top loaded monopole Antenna.
Page 2 REV-H Controls and Connections: 1. Main Display – LCD. Display backlight – flashes when battery is low 2. Power On/Off Switch 3. Control Buttons – SET, UP and DOWN 4. Two AA Batteries 5. Battery Cover – Screw Type 6. Microphone Element
Page 3 Quick set-up: 1. With the Power Switch on the transmitter OFF, install fresh batteries into the transmitter. 2. To prevent feedback or unintentional noise, mute the audio mixer/amplifier or other device during set-up adjustments. Place the transmitter Power Switch to the ON position. 3. The operating screen (display) light will come on momentarily. The display will current frequency group and channel and the battery level. Note: Anytime Power is removed and turned back on, the GP/CH/Bat screen will be displayed. 4. The screen will stop at the GP (Group) and CH (Channel) screen. If the Group and Channel match the desired receiver group and channel, Proceed to Step 11. If not, proceed to Step 5. 5. To select a different GP/CH, press SET one time. The Group will start flashing. Use the up and down arrows to change the group number. Press the SET button to save the Group. 6. After setting the Group, The Channel number will start flashing . Use the up/down arrows to change the Channel number. Press SET and the channel is now saved. 7. There are 10 Groups and up to 16 Channels (preferred groups/channels) stored in memory. If desired, you can create new groups/ channels but you must change to a new frequency to store in that group/channel. 8. In order to select a new frequency, you must have a “users” group /channel selected. Press the SET button. The Group should be flashing. Press the Up arrow until a group ending with u is found (any u group can be used) Press SET. The Channel should now be flashing. Select a channel with the up/down arrow. Press SET. 9. You are now ready to select a frequency to store in the users group above. Press and hold the set and down arrows at the same time for 3 seconds and release to go to the next screen function.
Page 4 10. The next screen displays the operating frequency of the group/channel. If there is no frequency currently stored in the selected users group/channel, a dashed line will be shown. Press SET. The dashed line or frequency will start flashing. Press the up arrow one step at a time to find the desired frequency or hold down the up arrow to scroll through the frequencies quickly. The frequencies can be scrolled either way by the up/down buttons. When the desired frequency is showing, press SET. 11. Press and hold the set and down arrows at the same time for 3 seconds and release to go to the next screen function. 12. The next screen is the audio (microphone) level (attenuator) screen. Setting the level correctly depends on the microphone used and the person using the microphone. Setting the attenuator to “0”db is the same as setting a control to maximum gain. Setting the attenuator to –42 db is the same as setting a control to minimum gain. Each step of the attenuator equals 3 db. Setting the attenuator for the maximum Audio Meter reading on the receiver without peak distortion will produce the best signal to noise ratio. 13. The next screen is RF Power. The Transmit Power (RF) is shipped set to “Lo” for use with multiple frequency systems and the best battery life. “Hi power can be selected for longer distances or to suppress noise or interference. The nominal power in Hi is 50 milliwatts. 14. When power off is required, simply place the power Off-On switch in the OFF position. The display will then delay slightly to allow the receiver to shut down quietly.
