LECTROSONICS, INC. 6
Compatibility Mode
In addition to it’s native Digital Hybrid mode, the transmitter will operate with Lectro-
soncs 100 Series, 200 Series and IFB receivers, as well as several analog receivers
from other manufacturers.
From this screen, use the UP and DOWN arrows to select the desired
mode.
• CP 100: 100 Series mode
• CP 200: 200 Series mode
• CP 3: Mode 3 (contact the factory for details)
• CP 400: 400 Series mode
• CP IFB: IFB Series mode
• CP 6: Mode 6 (contact the factory for details)
Output Power
Extended operating range and increased immunity to dropouts can be
selected at the expense of shorter battery life by setting the output
power to 250 mW. Reduced output power will decrease power consumption and extend
battery life at the expense of operating range and immunity to dropouts. Use the UP and
DOWN arrows to select the desired output power.
NOTE: See the specifications for typical operating times with different batteries and power
levels.
Bias Voltage (phantom power)
The transmitter features unique Servo Bias input circuitry that automatically adjusts the
current to maintain a selected bias voltage for the microphone. This effectively over-
comes a traditional problem with variations in output levels and power supply currents
of different microphones.
Hold the UP arrow button, then press the
Audio and Freq buttons together to enter the
setup screen with the RF output turned off.
Press the UP and DOWN arrows to select the desired setting:
• PH 2 Bias at 2 volts for electret mics
• PH 4 Bias at 4 volts for electret mics
• PH oFF Bias turned off for dynamic mics
• L InE Bias turned off; live level impedance
The correct bias voltage will be specified by the microphone manufacturer. 4 volts is
typical for most electret lavaliere microphones. 2 volts is preferred by some mic manu-
facturers such as Countryman for the models B6 and E6.
LCD Backlight Settings
The backlight on the display can be set to stay on all the time or to turn
off after either 30 seconds or 5 minutes of inactivity on the panel
switches. The backlight will turn on and the timer will start over when a
button is pressed. Use the UP and DOWN arrow buttons to select the desired setting.
