Rolls HA243 Headphone Amplifier
A four-channel headphone amplifier, the Rolls HA243 lets each listener pick between two stereo sources with an A-B switch.
The A and B inputs each take RCA, 1/4-inch, or 1/8-inch connections, and each can be switched to mono.
Every channel has its own level control and both a 1/4-inch and a 1/8-inch stereo headphone output. Each channel delivers 652 mW into 62 ohms, 326 mW a side. It gives up to 20 dB of gain and drives headphones from 8 to 1000 ohms. A 15 VDC power adapter is included.
