Bosch PRS-1P500 Power Amplifier
195,000৳Add to cartThere are four types of Power Amplifier units in the Praesideo product range. These differ in the number of amplifier channels per frame: one, two, four, or eight. The overall power rating is 500 watts for all of the amplifiers. The Power Amplifiers can be set to 100 V, 70 V, and 50 V output tappings. They have short-to-ground and short-circuit detection functions, and can generate their own pilot tone for supervision purposes

Bosch PRS-CSR Call Station Remote
65,500৳Add to cartThe PRS-CSR is a call station with the same functionality as the basic call station, LBB 4430/00, but it uses CAT-5 cable for its connection to the Praesideo network. It connects, one-to-one, to the call station interface, PRS-CSI, which is part of the Praesideo optical network.
The CAT-5 cable, carrying digital audio and control data, can be as long as 1 km. The length of the CAT-5 cable is not a part of the Praesideo optical network length. This considerably increases the overall possible length of the optical network.
The PRS-CSR can be extended with up to 16 keypads (LBB 4432/00 or LBB 4434/00), each with eight programmable keys. Extension with a numeric keypad (PRS-CSNKP) is also possible.

Call Station Numeric Keypad
50,500৳Add to cartThe Call-Station Numeric Keypad is used in combination with a basic or remote call-station. The call-station provides the microphone and press-to-talk key, while the numeric keypad can be used for user access, zone and zone group selection. It works together with call-station keypads for pre-configured actions. The built-in LCD provides feedback to the user.

BOSCH PRS-2P250 Presadio Controller
235,000৳Add to cartThe Power Amplifiers receive input signals over the network. They also have two auxiliary audio inputs (four for LBB 4428/00) for local audio. Their eight control inputs are freely programmable for system actions, and priorities can be assigned to these inputs. Each control input has the ability to monitor the attached line for open and short-circuits. Control outputs are freely programmable for faults and call-related actions.
The 2 x 16‑character display and the rotary control enable local status inquiries. The display shows the VU‑meter reading when the audio monitoring mode is active. Audio can be monitored by headphones. The units are self-monitoring and continually report their status to the network controller. They support both single branch and redundant loop cabling. The amplifiers have a changeover facility for spare power amplifier switching. Changeover relays are included with the units. The amplifiers have a 48 V DC back-up supply input. The digital audio processing can handle three parametric equalization sections and two shelving equalization sections per channel with configurable audio delay.
Controls and indicators • 2 x 16-character LCD for status display • Rotary/push control button • Mains switch • Voltage selector for PRS‑xPxxx Interconnections • Mains input • Battery backup input • Two system network connections • Two mic/line inputs (four for LBB 4428/00) • Selectable 100 V, 70 V or 50 V outputs (per channel) • Fixed 50 V output • Eight programmable control inputs • Control output (for each amplifier channel) • Headphone output • Spare amplifier connection (for each amplifier channel)
