Example 1: Mono Pedals, Single Amp
In this example, two pedals are linked together with a short cable going from the output of the rst to the input
of the second. Since there is only one amp, only the Left/Mono channel is used.

A Note On The Current Requirements Of Pedal Effects
Each of the SPB-8C’s 9VDC outlets has a maximum current rating of 100 mA, yet certain pedals state
power requirements of 200 mA or more. Most of the time, these specications are more indicative of a desired
level of regulation from a wall wart than an actual constant current requirement. Typically, the actual current
draw is no more than 50 mA, so the SPB-8C’s supply will in fact be more than adequate. To conrm this, try
it! There is no harm in trying one of the SPB-8C’s 9VDC outlets on any pedal or box. If the constant current
draw actually exceeds 100 mA, the PTC (solid state fuse) will shut off, without damage, until the excessive
load is removed. If this occurs, simply unplug the device and use one of the SPB-8C’s AC outlets with an
appropriate wall wart supply. To further illustrate this point,consider this: If a battery-powered device were ac-
tually to draw 300 mA continuously at 9VCD, it would consume a new alkaline battery every six minutes.
