Frequency characteristics are flat. Input level: 300 mV rms*4 21 EXT.I/O 21 Function assignable.*1 (Default: Analog Audible Output) +5 V pull up, Active=L 22 AF OUT The AF detector Output. - 23 EXT.I/O 23 Function assignable.*1 (Default: Mic Mute Output) +5 V pull up, Active=L 24 EXT.I/O 24 Function assignable.*1 (Default: Null) +5 V pull up, Active=L 25 EXT.I/O 25 Function assignable.*1 (Default: Mic Hanger Output) +5 V pull up, Active=L *1 The desired function can be assigned using the optional CS-FR5000 cloning software. Ask your dealer for details. *2 (For the European versions) Input impedance: 2.7 kΩ Input level: 85 mV rms (for 60% deviation) NOTE: If the input impedance is changed to 27 kΩ, a 300 mV rms input level is needed for 60% deviation signal. *3 (For the European versions) Output level: 300 mV rms. Received 60% deviation signal. *4 (For the European versions) Input impedance: 47 k Ω Input level: 300 mV rms (for 60% deviation) 3
