MUTE 103.5 MHz FREQUENCY DN UP FM TRANSMITTER PWR 15 VDC 1 2 OUTPUT LINE IN AUX IN ON MIC DISPLAY: LCD display showing the active information relevant to the current operation of the HR70. MIC/LINE: When pressed in, the gain of the XLR Mic In is reduced by 30 dB. CLIP: LED for indication of when the circuit is over driven/clipping. MUTE: When pressed unit will MUTE. LEVEL: Adjusts the level of output. FREQUENCY UP / DN: Selects the frequency that the HR70 is transmitting. RELEASE TIME: Adjusts the amount of time for the ducked signal to return to its normal level. Counterclockwise; slow - Clockwise; fast. MIC LEVEL: Adjusts the amount of gain for the Mic In circuit. DUCK SENSITIVITY: The Threshold at which ducking begins. When the microphone level reaches the threshold, the signal present at the Line In jacks is reduced until the announcement is over, then the Line In signal returns to its previous level. A NOTE ON THE HR70 THRESHOLD SETTING, WITH THE SENSITIVITY CONTROL FULLY CLOCKWISE: If a signal is on the XLR input, the ducking will begin (the threshold is) at -30 dB when the Mic/Line switch is set to Mic, and 0 dB when the switch is set to Line. If the control signal is on the RCA input, ducking begins at -30 dB.

- Connect the Rolls supplied adapter to the VDC power jack of the HR70, then to an AC outlet with the proper voltage.
- Connect the HR70 Left and Right line input to a mixer, or other audio device. FM TRANSMITTER WE RECOMMEND TURNING THE DUCK SENSITIVITY FULLY CLOCKWISE (ALL THE WAY UP) TO START. THIS IS THE HIGHEST SENSITIVITY AND MOST DUCKING AVAILABLE ON THE UNIT. OPERATION If you are using a condenser microphone, switch the Phantom Power on. Set the level of the music signal
(Line In) for a comfortable level. Speak into the microphone and adjust the Mic Level for a comfortable level, then adjust the Sensitivity so that the music is muted when speaking with a normal voice. Set the Release Time control for the amount of time you wish for the Aux In signal to return to normal.
