Baldwin Boxall Line Vox Unit BT10

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.

Baldwin Boxall 100W Volume Controls with Override Relay BVC100

Baldwin Boxall 100W Volume Controls with Override Relay BVC100

Baldwin Boxall 100W Volume Controls with Override Relay BVC100These volume controls are designed to attenuate the signal fed to loudspeakers driven by the 100-volt line output of a public address amplifier. The volume control is fitted into a double gang surface mounting box and can be used with any number of loudspeakers provided the load does not exceed 100 Watts. The control has 9 steps of 3dB. The knob is fully rotating. A volume restoration relay is fitted and operates in the same way as the BVC6.

Baldwin Boxall Ambient Noise Sensor BVRAMB

Baldwin Boxall Ambient Noise Sensor BVRAMB

Baldwin Boxall Ambient Noise Sensor BVRAMBWhen designing a voice alarm system for areas of variable levels of ambient noise which could cause problems with audibility noise sensors should be included. Correctly placed ambient noise sensors will ensure that all announcements are clearly heard.Key FeaturesTwo versions are available BVRAMB - standard version. BVRAMBIP - IP65 rated version.Monitors the ambient noise in a given area.Automatically adjusts the power of the amplifiers depending on noise level.When the area is at its quietest the level of the announcements or music will reduce.During busynoisy periods the volume level adjusts to suit.Used in conjunction with a BVRDCI CANBUS interface module which connects to the VIGIL EVAS routers.Uses a dynamic microphone capsule the output of which is amplified and converted to produce a variable current.This output is used by the BVRDCI module to produce a voltage that is proportional to the ambient noise.Band pass filtering ensures that the system only responds to ambient noise affecting the intelligibility of announcements.An on-board surveillance tone generator permanently monitors the microphone capsule. A system fault will be indicated should the microphone capsule or on-board amplifier fail.The BVRAMB includes an option to allow one of three response speeds to be selected SLOW - the system will only respond to an average change of ambient noise. MEDIUM - suitable for most installations. FAST - the system will react to short duration changes in ambient noise.Two units can be wired in parallel on the same input to monitor the ambient noise over a larger area.
