11. GAIN SElECTOR SwITCH

Gain can be changes in 10 steps from 0 to –27 dB in 3 dB units.

The Gain selector switch sets the Microphone/instrument input gain

maximum at "0 dB" position and minimum at "–27 dB" position.

If a loud voice distorts the output sound, decrease the gain by setting the Gain

selector switch to the "–3 dB" position or less with the supplied screwdriver.

Note: The Gain selector switch is factory-preset to "0 dB."

12. TEST mODE ON/OFF SwITCH

• Holding down the Test mode ON/OFF switch for 1 second or more with the supplied

screwdriver causes the test signal to be transmitted. (This condition is referred to as the

Test mode.) Press this switch again to return to the usual condition.

Note: Do not press the switch too strongly with a sharp-pointed object, as this may cause

unit failure.

• Once the power is turned off, the test mode will be released the next time the power is turned on.

• While in test mode, the receiver does not output audio signals even if it receives the radio signals from the

wireless transmitter.

• For the test signal operation, refer to the S-D7000 Digital wireless system's Setting software instruction

manual supplied with the S-D7802 Digital Wireless Receiver

.

13. mICROPHONE/INSTRUmENT SElECTOR SwITCH

Set the switch to the appropriate position for the equipment to be connected to the

Microphone/instrument input.

Note: Make the switch setting before turning on the power switch.

• Place the switch in the "MIC" position when connecting 2-wire condenser

microphone. In this case, the internal impedance is about 10 kΩ and the internal

phantom power (5 V) turns on.

• Place the switch in the "INST" position when connecting a musical instrument such

as an electric guitar. In this case, the internal impedance is over 500 kΩ and the

internal phantom power (5 V) turns off.



Note


Place the switch in the "INST" position as well when connecting a 3-wire microphone.
