The B-FW1 is an analogue single channel four wire beltpack which includes a built in speaker.
The talk buttons can be programmed to operate push to talk, latching or 'smart' (tap to latch, push to talk).
Programming the B-FW1 is simple using the OLED display which also shows line input and output levels during normal operation.
The following features are programmable:
• Microphone amplifier gain range 30dB to 60dB
• Phantom power on/off
• Highpass filter some/lots
• Mic automatic gain control none/some/lots
• Line input gain 6dB, 12dB or 18dB of gain
• Headphone limiter some/lots
• Sidetone on/off/full level/-6dB/-12dB
• Loudspeaker on/off
• Talk switch mode momentary/latching/smart
Power requirements are a PP3 size 9V battery (alkaline recommended) or a 9-16 volt external DC supply.
