Product Description
The Rolls RA163 is an outstanding distribution amplifier tailored for contractors and installers. It can operate in either mono or stereo mode, offering flexibility for different setups. In mono, it takes a single input and distributes it to eight outputs, while in stereo, it can handle stereo inputs and send them to four stereo outputs. With a +20 dB gain switch, it can boost the signal as needed. All its inputs and outputs use XLR jacks, ensuring high - quality connections. This amplifier is designed to drive high - level balanced lines in sound distribution systems, and each output can power multiple lines. Technical specs include an input impedance of 100 K Ohms balanced, a max input level of +24 dBV, and an output impedance of 50 Ohms balanced. It has a max output level of +24 dB, a max gain of 20 dB, an S/N ratio greater than 90 dB, and a frequency response from 10 Hz - 40 kHz, +/- 1 dB. The THD is less than.008%. It runs on 120 VAC 50 - 60 Hz, 15VA, and measures 19” x 1.75” x 6.5” (48 x 4.5 x 17 cm) and weighs 7 lbs. (3 kg).
Using the Rolls RA163 is straightforward. First, connect your audio source to the XLR input jacks on the rear panel. Depending on your needs, you can set it to mono or stereo operation. If you're using mono, a single input will be sent to eight outputs. For stereo, connect your stereo source and it'll go to four stereo outputs. You can use the +20 dB gain switch if you need to boost the signal. When it comes to power, make sure to plug it into a 120 VAC 50 - 60 Hz power source. As for maintenance, keep it in a clean and dry place. Regularly check the XLR connections to ensure they're secure and free of dirt. If you're not using it for a long time, unplug it from the power source. Also, avoid exposing it to extreme temperatures or humidity, as this can affect its performance.
