options - Plug and play easy to use
The Radial J+4 is a stereo interface designed to accept unbalanced low
output level devices such as instruments, computers or CD players and boost the
signal to a balanced +4dB level for easy manipulation in professional
environments such as broadcast, recording studios and live touring.
The design begins with 100% discrete components for optimal signal
transfer. Careful attention has been paid to eliminate noise by combining the
advantages of active signal buffering with transformer isolation. The J+4
delivers better than 95dB signal to noise while ensuring hum and buzz caused by
ground loops along with spurious noise from clocking does not pollute the signal
path. For ease of use, controls have been kept to a minimum. This includes a
stereo level control, a high pass (low cut) filter and ground lift. The choice
of input connectors include a stacked set of ¼`` jacks for DJ mixers or
keyboards, RCAs for CD players and a mini 3.5mm for iPods.
As with all Radial products, the Radial J+4 is built tough to handle the
extreme rigors of professional touring. A unique 14-gauge steel I-beam inner
frame ensures the sensitive PC board will not be subjected to outside stress
which could potentially cause solder joints to fail. An innovative book-end
outer shell creates protective zones around the controls, switches and
connectors to further improve dependability while a full bottom no-slip pad
provides both mechanical and electrical isolation.
The Radial J+4 balanced line driver delivers exceptional sonic performance,
plenty of headroom and ultra low noise making it the ideal companion for today's
more demanding professional audio systems.
