R-501 Mic-Line Preamplifier has been conceived to offer to the API 500 user the superior audio performance of the ARREL Audio higher level series products. The unit offer to the 500 user high reliability, rugged design, outstanding audio quality, versatility and ease of use typical of the tradition of ARREL Audio products.
R-501 is perfect for recording every kind of music from classic, pop/rock, electronic and in all the situations (live and recording studio) where maximum sound quality and special attention to dynamic range and signal to noise ratio is needed.
The R-501 technical specification shows that it is the perfect audio unit also for actual digital recording 24bit/192kHz environments where superior performance is required. R-501 is based on the use of the latest circuit topologies, characterized by very low distortion, ultra-low noise and very wide frequency response. The amplifier architecture is based on two high dynamic range gain stages in order to avoid any saturation.
Even if the input stage of the R-501 do not saturate up to +24 dBu, a special protection circuit limits the input level at +20 dBu in order to prevent any damage. The extended input dynamic range avoids the necessity of the input pad.
Moreover a special circuit allows the connection of microphones even if the unit is turned on with the Phantom Power activated.
The Line Input is easily accessible from the front panel by a 1/4"' jack, the jack insertion excludes the mic input.
Three buttons with LEDs for : Phantom Power, Phase inversion, LO-CUT filtering are provided.
A LED bargraph (10 LEDs) is used to display the output level.
620 Euro
R-501 is dedicated (due to his absolute sonic level quality) to high professional vocal recordings, classical instruments, high dynamic range instruments such as drums and percussions.
