Usually arrives in 5-9 business days.
The TX-TPR1A is a precision active single-pair receiver in sleek blue, designed for professional audio applications that demand clarity and flexibility. It provides a balanced line output with options for single-10 dBV unbalanced or +4 dBu balanced connections, using either a phono jack or a detachable terminal block. A simple switch lets you select which input pair (A, B, or C) feeds the output, while signal and power pass through to the LOOP OUT jack for easy daisy-chaining.
Powering the TX-TPR1A is flexible and convenient. The module can operate on local power via a terminal block or DC jack, or receive remote power through its RJ45 connection. A fused local power system supplies all modules connected to RJ45 jacks, while a bright blue LED confirms the module is powered. Multiple units can be daisy-chained to expand system coverage without sacrificing performance.
Inside, the TX-TPR1A features studio-quality precision active balanced circuitry that ensures clean, low-noise audio transmission over twisted-pair cabling. Compact, durable, and easy to integrate, this blue module is a versatile solution for broadcast, studio, and professional AV environments.
