RA-53 5-Channel Headphone Amplifier
The RA53 is a five-channel headphone DA
(distribution amplifier) with a variety of input
options. There are four different ways to send a
master mix to the RA53; Discreet 1/4˝ Right and
Left inputs, Right and Left RCA jacks, a
1/4˝stereo TRS plug connected to the Right input,
or a 1/4˝ mono TS plug connected to the Left input. In addition to the four master mix input configurations, three separate
mixes can be monitored using the main inputs and the two Insert jacks on Channels 1 and 2. Inserting a 1/4˝ TRS jack into
Inserts 1 and/or 2 interrupts the master signal, sending different mixes to Channels 1 and 2, leaving the master mix on
Channels 3 through 5.
◆ A 1/4˝ Link Input/Output jack is provided for connecting two
RA53s together, allowing up to ten stereo channels of headphone
monitoring.
◆ Each channel has a Level control and a stereo 1/4˝output jack.
◆ The RA53 is loud, has plenty of gain for operation in noisy
environments,and works with most any headphone impedance.
