Clarus head; Coda, Corus and Ten2 combo; and Coda EX, Corus EX
and Ten2 EX extension cabinet.
The Basics
Our Series 4 product line consists of two amp heads, and three
speaker cabinets. The heads mount in the cabinets using our
exclusive Cabrio Docking System to form six different combo amps.
The amp heads use the same superb class-D power amplifier with a
switch mode power supply and a sophisticated, sensitive preamplifier
with one or two channels. The speaker cabinets have a 1x10 or 2x10
speaker configuration. The features of the preamp and the speaker
configuration define the specific head or combo model. The Clarus
amp head combines the power amp with either a one channel or two
channel preamp. The Coda combo has a 1x10 speaker configuration
with a poly cone woofer. The Corus combo has a 1x10 speaker
configuration with a paper cone woofer. Both have a 5 inch extended
range driver with presence control in addition to the woofer and both
are available with a one or two channel head. The Ten2 combo uses a
2x10 speaker configuration (one downfiring, one front firing) with poly
cone woofers in conjunction with a 2.5 inch tweeter. The Ten2 is
available with a one or two channel head. Each cabinet type is also
available as an extension speaker in either a “Cabrio-ready”
configuration or as a fixed extension cabinet (Coda EX, Corus EX or
Ten2 EX).
The Clarus integrated amplifier uses our 600W power amp and a one
or two channel preamp. The power amp is a high efficiency design that
requires no external heat sinks or cooling fans and is capable of
driving loads as low as 2 ohms. The rated output is 600W at 4 ohms.
AC power and output speaker jacks are located on the rear of the
chassis. A standard, three-prong detachable AC power cord is used
to provide power to the unit, while an AC voltage selection switch
allows the unit to operate at 100 to 120V (50 or 60 Hz) or 220 to 240V
(50 Hz). The input channels of both preamp types incorporate combo
jack interfaces that allow either a high impedance instrument input (to
optimize the sound of piezo-type pickups) or a mic input with a
switchable 10 dB pad, a three-band EQ, an effects loop with return
level control, a selectable low cut filter and phase reverse switch for
feedback control and reduction of low frequency boominess, a six-
program effects unit with wet/dry mix control, a direct out capability
with ground lift and pre/post EQ switch, a master level control and a
