The Rolls HA243 is a powerful stereo headphone amplifier designed to elevate your audio listening. It offers four channels of amplification, each with independent A-B input switching for seamless monitoring.
Key electrical specifications include an input impedance of 10 kOhms and a maximum input level of +26 dBV. The amplifier delivers a maximum gain of 20 dB per channel, with an output power of 326 mW per side at 62 Ohms, and 652 mW per channel at 62 Ohms. The frequency response spans from 20 Hz to 20 kHz with a +/- 3 dB tolerance, and it boasts a signal-to-noise ratio of 92 dB.
Connectivity is versatile, with RCA, 1/4”, and 3.5mm inputs available for both A and B sources. The unit provides four 1/4" TRS stereo headphone outputs and four 1/8" (3.5 mm) TRS stereo headphone outputs. The HA243 supports switchable mono or stereo operation for both A and B inputs, offering flexibility in setup.
Physically, the HA243 measures 6.75" x 1.75" x 4.75" and weighs 1.65 lbs. It operates on a 15 VDC power supply, with an adapter included. The headphone impedance range is specified from 8 Ohms to 1000 Ohms, with a warning against using impedances lower than 8 Ohms to prevent damage.
