Rolls MX44 Pro Four-Channel Stereo Mixer
A four-channel stereo mixer, the Rolls MX44 Pro brings up to four stereo line-level sources, such as phones, laptops, instruments, and CD players, down to one stereo output.
Each input takes a stereo RCA pair or a 1/8-inch (3.5 mm) TRS plug and has its own volume control, and the mix leaves on a stereo 1/8-inch jack. The MX44 Pro is not a headphone amplifier, but its output has enough level to drive headphones or earphones for limited monitoring.
A mono tip-sleeve plug in an input is heard on the left side only, so a mono source goes in on a TRS plug with the tip and ring tied together. Never put a mono plug in the output, since it can damage the unit.
The MX44 Pro runs on one 9-volt alkaline battery in a removable compartment or on the included Rolls PS27s 15 VDC adapter, with a latching power button and a power LED.
