Biamp Tesira Operation Manual

All Tesira® Amplifiers are AVB/TSN enabled, digital networked, multi-channel amplifiers. Models include the AMP-4175R, AMP-4300R CV, AMP-4350R and AMP-8175R. The Tesira Amplifiers function as an integrated part of a Tesira audio system that is configured through the Tesira configuration software. The amplifiers serve as a dedicated endpoint making installations easier to design, support and maintain. The front panel OLED display allows for adjustments such as single-channel mute or all-channels mute and provides feedback on overall status and channel performance. All models feature impedance monitoring, as well as ...

Setup and Use The Tesira software provides an intuitive interface for configuration of the Tesira amplifier devices. The information supplied by this manual relates to physical connections and assignment. For more details on software setup, please consult the Tesira Help File. Installation The unit requires one 3.5 inch (88.9mm) high and 19 inch (483mm) wide rack space with 17.5 inch (444mm) depth. Mounting the unit using four screws with washers will prevent marring of the front panel. Install the unit away from heat sources, such as vents and radiators, and in rooms with adequate ventilation. Ensure that air c ...

The LED indicators on the front panel of the amplifier provide information and operational status of the amplifier and its associated output channels. LED layout and channel meters vary between amplifier models. LED’s are grouped to show chassis status indication and amplifier channel status indication. 1. Air Vent / Grille 2. Channel status - Signal, fault, failover and mute 3. Chassis status - Power, alarm, activity, status, ais (Alarm In System) 4. Oled screen 5. Screen navigation – Up, down and select ...

Above: Rear Panel of Tesira Amplifier 8175R (top) and 4300R CV (bottom) Conventions All numbered audio, relay and power connectors on the rear panel of the amplifier are configured with the lowest output or input on the right of the connector as viewed from the rear of the unit. AC Power Socket Provides for connection of the appropriate power cord. Each amplifier uses a switch mode power supply that has an operating voltage of 100-240V at 50/60 Hz. The Tesira AMP-8175R, AMP-4350R and AMP- 4300R CV Current draw is 3 – 2.2 Amps. The Tesira AMP-4175R Current draw is 2 – 2 Amps. CAUTION Do not remove or defeat the ground prong on ...

Amplifier Output Connections Speaker Connection To minimize power loss, use a speaker cable of appropriate gauge for the load impedance. For long speaker cables, to minimize high frequency loss, choose a low capacitance cable. Use the supplied plug- in barrier strip connectors to connect loudspeaker level outputs. If stranded speaker wire is used, be sure to incorporate all strands into the connector, as stray strands can short to the adjacent terminal or chassis. Do not leave excessive bare wire outside the terminals, as this can lead to shorts. Use of the supplied cable restraints is required to secure the cable in the connecto ...
