Baldwin Boxall Line Vox Unit BT10
Baldwin Boxall Line Vox Unit BT10The BT10 is a universal interface module. Connect the input of the BT10 to either a 100 Volt loudspeaker line or the line level output from a telephone switch.The output at either microphone or line level can be fed into an amplifier. When a signal of a sufficient level is received at the input the Vox circuit will operate and it will be passed via the output into the amplifier.In addition the unit has a switched 0V available on the ACC terminal to access the amplifier. E.G. When using one of our amplifiers take a connecting wire from the ACC terminal to pin 5 on the appropriate input socket.The Vox circuit is designed to ensure that there will not be any unwanted noise appearing at the amplifier input and being relayed through the loudspeakers.A pre-set control allows adjustment of the Vox sensitivity. To set it adjust the control so that it only switches on when a suitable signal level is present.The TEST LED will illuminate when the Vox has operated and the access will be switched ON. The gain pre-set adjusts the gain of the unit and is factory pre-set at x 2 6 dB.It can be used to compensate for different input signal levels. The unit is powered from either mains or 24 VDC.If both are connected in the event of mains failure there will be automatic switch over to the 24VDC and the unit will continue to operate.
