Models CI-RJ2R-T and CI-RJ2R-R
Jensen ISO-MAX® Pro series audio interfaces are designed for use in the finest professional and audiophile sound systems.
They use the same industry-benchmark Jensen transformers that are installed in tens of thousands of the world’s best
recording studios, broadcast facilities, and sound reinforcement venues because of their sonic transparency, ultra-wide
bandwidth, and vanishingly low harmonic and phase distortion.
Models CI-RJ2R-T and CI-RJ2R-R are stereo (two channel) transmit and receive units, respectively, that allow transmission of
very high quality analog audio signals over standard “CAT” cables. Transmitter and receiver have an “Expand” connection
that allows two pairs of units and a single cable to support four audio channels. The units are designed for consumer-level
audio signals where the nominal or “reference level” signal is standardized at
!
10 dBV or 0.316 Vrms and a signal level of +5
dBV (1.75 Vrms) corresponds to 15 dB of “headroom.” Even at this maximum level, distortion (THD) is typically under 0.05%
at 20 Hz and drops to under 0.001% at frequencies over 500 Hz. Frequency response of the pair, linked by 50 feet of
standard CAT-5 cable, is +0/
!
1 dB from 1 Hz to 20 kHz and has a phase distortion (deviation from linear phase or DLP) under
2 degrees from 20 Hz to 20 kHz. Their exceptional sonic transparency, transient response and imaging performance makes
these units worthy of even the finest audiophile sound systems. Both transmitter and receiver are entirely passive and
require no power supply.
