Q & A
Chapter 13 Appendices
Q. What about the processor’s LINE input jacks?
A.
These inputs are labeled “LINE” to make it clear that no phantom power is supplied.
However, just as with the XLR connector (MIC) inputs, the input level is adjustable
between +4 and -60 dB. Therefore, you can also connect dynamic microphones to
these inputs. When connecting a high-impedance electric guitar or an instrument’s
Piezo pickup, a direct box or other such device is required.
Q. I want to send the cables connected to the input jacks on the
processor’s front panel behind the rack.
A.
With the addition of the optional RO-7000 Rack Mount Angle, you can mount the
processor so that the unit is situated downwards and back within the rack. If
approximately 1U of rack space is left open underneath, the cables can then be routed
to the back without the plugs extending beyond the front of the rack.
Q. Is VCA used for remote control of the preamp gain? How is the
sound quality?
A.
With the gain circuits, the discrete analog circuitry is digitally controlled from the
console. Dedicated VCA (voltage controlled amplification) ICs provide accurate
sound with zero distortion.
Q. The motorized faders seem to come to a stop rather slowly.
A.
This reduces the sound during movement of the faders. Internally, the audio signals
are changed instantly.
Q. How many increments do the faders move through?
A.
Mechanically, there are 128 fader steps. Internal sonic processing of input channel
levels and other crucial data is made over a range of 32,768 steps, thus allowing very
smooth changes in volume.
Q. How fast do the faders move?
A.
Physically, the motorized fader mechanism can go from minimum to maximum level
in approximately 0.3 seconds. Internally, the changes are processed instantly, with no
waiting for the faders to finish moving.
Q. Even when I move the fader, the fader graphic on the screen does
not respond instantly to the movement. Why is this?
A.
This is due to processing priority settings that prevent screen-refreshing from
affecting the speed at which the actual sonic data is processed. Since processing of the
sound is completed with no pause for the refreshing of the screen, there is nothing to
worry about here.
■ Effects
Q. How many effects does the system include?
A.
A single processor is equipped with two general-purpose stereo effects processors.
This can be augmented by the installation of up to three optional VS8F-2 Effect
Expansion Board, for a total of up to eight stereo effects. Independent of these, one
master effect (for output insertion) is also provided. No matter which is selected, all
effects feature 24-bit internal processing for high-quality sound.
Q. What kind of internal effects are included?
A.
The system features a total of 39 algorithms for general effects such as reverb, chorus,
delay, and multi-effects for vocals, guitar, keyboards, and the like, as well as Roland’s
exclusive RSS effects, Mic Simulation, and Speaker Modeling. Three algorithms,
including an equalizer, can be used for the master effect. One algorithm (Speaker
Modeling) is used by both effects systems, for a total of 41 algorithms.
