The RDL TP-HA1A is a compact, Format-A stereo headphone amplifier designed for clear, reliable audio monitoring. It delivers 25 mW per side into 100-Ohm headphones with a wide frequency response of 10 Hz to 40 kHz (±1 dB) and exceptionally low noise of less than -90 dB. Powered conveniently via PoE through its dual RJ45 Ethernet ports, this amplifier is ideal for single-channel headphone monitoring in various professional audio environments.
Match your amplifier's power output (Watts RMS) to your speakers' sensitivity and impedance (Ohms). Do not obsess over astronomical peak wattage claims; RMS is the true measure of sustained power. Available from $165.79.
Amplifiers have practically zero ongoing costs aside from electricity, which is highly variable based on usage volume and class type (Class A uses more power than Class D). Good amplifiers can last decades with proper care. Consumables are virtually non-existent unless using tube amps.
Common Failure Modes
Solid-state amplifiers are extremely reliable. Failures usually stem from blown capacitors, overheated output transistors, or physical wear on volume potentiometers. Proper ventilation prevents 90% of heat-related failures.
Match your amplifier's power output (Watts RMS) to your speakers' sensitivity and impedance (Ohms). Do not obsess over astronomical peak wattage claims; RMS is the true measure of sustained power. Class D amplifiers run cool and are compact, while Class A/B offer traditional warm sound at the expense of heat and size.
Solid-state amplifiers can last 20+ years. Capacitors may eventually dry out and need replacement.
