Key Features

High-Density 1x7 Distribution: Provides one balanced input to seven isolated 75Ω BNC outputs.
Wideband Analog Compatibility: Supports analog video, subcarrier references, sync, and timing pulses up to 2V p-p across 30MHz bandwidth.
Selectable Input Impedance: Jumper-selectable 75Ω termination or 35kΩ Hi-Z input mode for passive loop-through setups using an external “T” connector.
Selectable Coupling & Gain: Provides jumper-selectable AC/DC coupling with ±5dB onboard gain adjustment for precise signal-level trimming.
High Common Mode Rejection: Delivers >70dB CMRR at 1kHz with a >6V p-p common mode range for improved hum and ground-loop rejection.
Fail-Safe Multi-Frame Integration: Maintains input impedance during card power loss and occupies one slot in Evertz 7800FR, 7801FR, 350FR, or standalone frames.

Product Overview +

Professional High-Density Analog Signal Distribution

The Evertz 7700ADA7 is a general-purpose 1x7 analog distribution amplifier designed for master control, broadcast facilities, and live production environments. Engineered to distribute a full spectrum of analog video signals, subcarrier reference, and timing pulses, it delivers seven clean, isolated outputs from a single balanced input.

Flexible Coupling & Signal Conditioning

Built to preserve analog signal fidelity across complex routing networks:

Impedance & Looping Control: Jumper-selectable 75Ω termination or high-impedance (35kΩ Hi-Z) mode allows operators to loop incoming signals using an external "T" connector without loading down the line.
Coupling & Level Calibration: Supports jumper-selectable AC or DC coupling to accommodate standard video waveforms or DC-offset pulse signals, paired with a ±5 dB gain adjustment trim.
Interference Rejection & Fail-Safe Design: Features a balanced input with high Common Mode Rejection (>70 dB at 1 kHz). In the event of a chassis power loss, the card maintains constant input impedance to prevent signal degradation on passive loops.

Universal Modular Compatibility

The 7700ADA7 installs into a single card slot across Evertz modular enclosures, including the 3RU 7800FR (up to 15 slots), 1RU 7801FR (up to 4 single slots), portable 350FR (7 slots), or standalone single-card desktop enclosures.
