The R-601 is a Guitar/Bass splitter designed for the most demanding professional recording studios where guitar systems, and multiple amplifiers are used simultaneously. The R-601 design, based on four separated transformers, is able to drive up to four amplifiers at the same time without noise and ground loops problems that often plagues most systems. Its high input sensibility allows coupling even with battery powered DI Boxes or with unbalanced low level outputs.

This amplifier is characterized by very high linearity and dynamic range, with distortion and noise at the lowest limit, resulting from the use of advanced circuit topologies. Signal level is controlled by a potentiometer allowing a 35 dBu range (-25 dBu to +10dBu). Input and output impedance is calibrated in order to obtain the best pairing with guitar/bass amplifiers. 48V Phantom Power provides power to the DI box if needed.

The target amplifier can be selected by using the front panel buttons, a footswitch or by a wireless remote control. This feature allows the musician to switch amplifiers (located in the recording room) comfortably from the control room. More than one amplifier can be selected at the same time. When the channel buttons are switched off, the remote control (footswitch or wireless remote control) is automatically activated.

    R-601 Key-Technologies

  • LARGE BANDWIDTH (LBW)

    Large Bandwidth (LB) means a very fast transient response able to represent the original sound with the maximum temporal resolution. LB is required to improve the perception of a “real sound” and to represent the details of the original sound.

  • PERFECT SQUARE WAVE (PSW)

    Large bandwidth plus very low total harmonic distortion means a perfect square wave reproduction.

  • ULTRA LOW NOISE (ULN)

    Ultra Low Noise (ULN) active and passive components and ULN design techniques. This requirement is especially important when the audio bandwidth is large as in the case of ARREL Audio products.

  • HIGH DYNAMIC RANGE (HDR)

    High Dynamic Range (HDR) means that the saturation probability of the output stages is very low. This is obtained by using special rail to rail circuits and by increasing the power supply voltage of the analog circuits.

  • ELECTROMECHANICAL FAULT TOLERANCE (EFT)

    Electromechanical tolerance means that electromechanical components are doubled in every situation in which maximum reliability it is important due to a frequent use (switches, push buttons, potentiometers).

  • THROUGH-HOLE TECHNOLOGY (THT)

    Through Hole technology means the maximum reliability in terms of thermal and mechanical stresses especially for connectors and electromechanical components.
