Baldwin Boxall VIGIL2 225W Class D Amplifier BV225

Baldwin Boxall VIGIL2 225W Class D Amplifier BV225

Baldwin Boxall VIGIL2 225W Class D Amplifier BV225The BV225 Amplifier module is a 225-Watt Class D Power amplifier with a 500mV Balance Line audio input and 100V Line output. The front panel status indicators show Power Overload and Output Level 10 and 100 output level. The audio input is presented on two separate RJ45 connectors. The output is presented on two 3-way plugcage clamp termination connectors providing 50V or 100V output. The 24V DC input is presented on a two 2-way crimp connected socket.The power output stage of the amplifier is protected against overload conditions i.e. short circuits or abnormal loads. Should an amplifier be subjected to an abnormal load the input to the relevant power amplifier is attenuated to a safe level and the Overload LED will be illuminated. The amplifier output voltages are also sensed and should they exceed 100V the relevant input signal will be attenuated ensuring safe operation without creating unnecessary distortion.Over temperature protection is provided using sensors attached to the output stage heat sink. Should the temperature exceed 90 Degrees Celsius the input signal to the relevant amplifier will be attenuated to a safe level and the Overload LED will be illuminated. If the system is under surveillance it will cause the surveillance detector to indicate a fault condition due to the gain reduction.

Baldwin Boxall 8 Zone Paging Telephone Interface BT8

Baldwin Boxall 8 Zone Paging Telephone Interface BT8

Baldwin Boxall 8 Zone Paging Telephone Interface BT8Our telephone interface units enable staff to make public address announcements from their own desk telephone. The free-standing units act as an interface between the analogue telephone system and the amplifier.Key FeaturesOperated by simply dialling the BT5BT8 extension number.Each unit is supplied with an IEC mains lead.Can be used to broadcast live announcements.Additional facility enables the user to pre-record an announcement. This reduces the risk of feedback where the telephone is adjacent to a loudspeaker.When connected to a telephone system with MF signalling the BT8 enables the user to select up to eight zones via the telephone keypad.An internal selector determines if the recorded message is played once or twice.Can be wired into any two-wire analogue extension port via a designated master extension socket. Another option is to connect the unit to the paging port available on most modern telephone switches. However they are not designed to operate on keyphone system extension ports.Outputs are selectable from line or microphone level.Signal output and zone select connections are via a 25 way D connector.Compatible with our BDM300 range of desk microphones connected via the BMS25 socket box supplied with the microphone.We recommend using our B81R relay unit for the zone select switching.Please note the BT8 is not approved for direct connection to the BT network. Under general approval NSG23J100003 it may be connected to a port on a telephone switch PABX. This unit should only be used with a switchable amplifier input.

Baldwin Boxall VIGIL2 Quad 50W Class D Amplifier BV050Q

Baldwin Boxall VIGIL2 Quad 50W Class D Amplifier BV050Q

Baldwin Boxall VIGIL2 Quad 50W Class D Amplifier BV050QThe Vigil2 BV050Q contains four independent 50 Watt Class D Power amplifiers each with one 500 mV balanced input and a 50 Watt 100V Line output. The front panel status indicators show Supply Healthy Overload Over Temperature and Output Level 10 and 100 max output level for each amplifier. The Active Indicator illuminates when the amplifier is not in Sleep Mode. CLASS D amplifiers are 80 efficient therefore reducing unwanted heat dissipation and power input requirements. Rated output power is obtainable using a 22V battery supply.The BV050Q has a Sleep mode automatically reducing the standby current requirement to typically 50mA per amplifier when operating on batteries. Channel gain may be individually set using the potentiometers on the board behind the front panel. The audio inputs to the amplifiers are presented on separate RJ45 connectors each connector providing the balanced audio input and a ground connection. The outputs are presented on 6-way plugscrew termination connectors providing 50V or 100V output. The 24V DC input is presented on a 2-way crimp connected plug and socket. The power output stage of the amplifier is protected against overload conditions i.e. short circuits or abnormal loads etc. Should the amplifier be subjected to an abnormal load the input to the power amplifier is attenuated to a safe level.The amplifiers output voltage is also sensed and should it exceed 100V the input signal will be attenuated ensuring safe operation without creating unnecessary distortion. Over temperature protection is provided using a sensor attached to the output stage heat sink. Should the temperature exceed 90 Degrees Celsius the input signal to will be attenuated to a safe level and the Overtemp LED will be illuminated. If the system is under surveillance it will cause the surveillance detector to indicate a fault condition due to the gain reduction. Up to three BV050Q Amplifier modules may be mounted in one BVMF equipment frame or more normally two amplifier modules and one switched mode power supply charger module.
