ART48 - SPRING
Routing section
The routing section involves various reverb outputs.
The output fader(11.), when manipulated, sends the reverb signal to
the master L and R outputs. The PAN knob(12.) alters the proportion of
reverberated signal sent to the left or right channel.
The AUX 2(13.), AUX 3(14.) and PFL(15.) knobs control the amount of
reverb signal sent to the respective auxiliary masters. The PFL, in this
instance, has a slightly different function, being used more as a “volume”
knob. For example, should the PFL master output be feeding an additional
stage monitor, this controllable PFL allows you to add a gradual amount of
reverb to the monitor line.
The spring unit also includes a separate AUX 1 output, referred to as the dry
out. Directly connected to the summed signal of the AUX 1 bus, it
enables the AUX 1 signal to be picked up parallel to the spring unit, in order
to drive an additional outboard reverb or other effects unit. These additional
effects devices will return via the return input on the L /R Master unit (mono),
or via a separate Stereo In or Multiple unit. The level of the AUX 1 output is
controlled by the dry out volume knob.
The spring unit as a stand-alone unit
As previously mentioned, the spring unit is also designed for use as a stand-
alone reverb that can be connected to any mixing console, added to guitar
pedals, or linked to a computer for home recording etc.
When connected to the ARTHUR mixer, the spring unit is powered by the
mixer’s supply, via the bus. When used as a stand-alone reverb, a power
supply (PS-12) must be connected directly to the unit’s DC In socket(16.).
The spring unit can receive a signal from two sources: the AUX 1 directly
from ARTHUR’s bus when used together with the ARTHUR mixer, or from
the external input, when used as a stand-alone unit.
The External Input(17.) includes a Ext In Gain(18.) control knob, which can
be found under the external input phone connector. The gain is adjustable
from -5dB to +20dB, enabling both line signals and weaker signals from
pedals, computers and other devices to be accommodated. Having
connected the signal source to the ext in, it will then appear at the send
fader for processing as described above.
When used as a stand-alone unit, the spring unit’s routing section, L/R fader,
AUX 1 and 2 and PFL will be out of action. This is because they normally
“look” to the mixer’s bus, which will not be here in this instance.
So, the output from the spring unit will, instead, be routed through the
reverb output section. The Volume knob(19.) sets the output level, while
the proportions of original sound (dry) and reverberated sound (wet) are set
using the Mix knob(20.).
If the spring unit is connected to a mixing console, you might set the mix
knob to the right (wet) in order to add the original sound through your mixer’s
loop. If using the unit with guitar pedals, where no parallel loop is provided,
the mix knob will then prove extremely helpful.
The Dry Out(21.) - whose level is controlled by the Dry Out volume knob
(22.) - drives the dry signal that is not influenced by the effect. This might be
useful for feeding another external effect or a stage monitor.
