Viking Electronics has announced the release of the PA-250-IP high-powered amplifier for unicast and multicast paging. This high-powered paging amplifier adds loud ringing, voice paging, and background music to VoIP SIP hosted phone service or a premise-based PBX. “Building on the success of our IP paging line, this high-powered IP paging amplifier is unique in its usability and efficiency,” said Paul Speltz, Engineer at Viking Electronics PA-250-IP rack-mounted paging amplifier The PA-250-IP is a 250-watt rack-mounted paging amplifier for 25V and 70V paging speakers and horns. Initiate voice paging with the PA-250-IP as a Unicast end point or add the PA-250-IP to a paging group for multicast paging. Additional inputs on the PA-250-IP allow for a contact closure to activate a door chime tone, a 1/8-inch audio jack for background music which mutes during a voice page, and a 600 Ohm AUX input for line level audio sources providing mass notifications, pre-recorded messages, or scheduled tones. Multiple amplifier protection modes The PA-250-IP features individual level controls with LED indicators for each input, automatic peak limiting, multiple amplifier protection modes, an adjustable Automatic Level Control, and Bass & Treble controls. For more power/speakers, multiple units can be daisy chained together using the 600 Ohm output.
The high-powered PA-250 combines loud ringing, voice paging, and background music into one paging amplifier for easy broadcasting. The compact design fits into a single 1U rack space and can be used with both new and previously installed paging systems. “This is our largest amplifier yet and I’m excited to bring trusted Viking quality to this large of a scale”, says Paul Speltz, Sr. Engineer, Viking Electronics. The PA-250 is a 250-Watt rack mounted paging amplifier for 25V and 70V paging speakers or horns. Easily initiate a voice page using an FXS or FXO port, a 600 Ohm Paging port or a microphone with push to talk capabilities. Multiple amplifier protection modes The 600 Ohm AUX input on the PA-250 allows for flexibility when connecting to other line level audio sources and the night transfer switch input toggles loud ringing on and off. Additional inputs can be used to activate a door chime tone, provide background music, or trigger loud ringing. The PA-250 features individual level controls with LED indicators for each input, automatic peak limiting, multiple amplifier protection modes, an adjustable Automatic Level Control, and Bass & Treble controls. For more power/speakers, multiple units can be daisy chained together using the 600 Ohm output.
Viking Electronics’ TBB-1B is an in-line device that actively boosts talk battery power to analog devices. “It’s getting more common that FXS ports and analog extensions don’t produce enough talk battery. The TBB-1B solves this problem and it is simple to use.” Paul Speltz, Sr. Engineer, Viking Electronics TBB-1B talk battery booster Use the TBB-1B to boost talk battery from a VoIP phone system ATA with an FXS port, an analog PABX extension, a VoIP cable modem, a POTS line and more. The incoming under powered line is connected to the TBB-1B where talk battery voltage is boosted to 48V DC. The line with boosted talk battery now travels from the TBB-1B to the analog device. Analog devices that can benefit from the use of the TBB-1B include elevator phones, emergency and area of refuge phones, alarm panels, door entry phones, and traditional analog telephones.
