mute switch. The two-channel preamp has a switch that allows the
second channel to be disconnected from the main amp and
connected to a satellite power amp to create a stereo system.
The Coda, Corus and Ten2 combo amps use either the one channel or
two channel Clarus head mounted in a speaker cabinet via the
docking system. The Coda and Corus use the same cabinet and
speaker configuration: a 10 inch downfiring woofer and a 5 inch front
firing extended range driver with a presence control. The difference
between the two is the woofer. The Coda uses a poly cone woofer, the
Corus uses a paper cone woofer. This gives the Corus a somewhat
different sound, one more suited for guitar. The Ten2 has the same
amp options but uses a slightly larger cabinet than the Coda/Corus. It
has a downfiring 10 and a front firing 10 with a 2.5 inch tweeter for high
frequencies A built-in, spring-loaded tilt mechanism allows each
cabinet type to be tilted back to better direct sound to your listening
position. The cabinets are made of an acoustically inert, high
durability, injection molded polymer material which dramatically
reduces the weight of the unit. Each unit (combo or extension cab)
comes with a fitted slip cover and shoulder strap. A padded case is
also available.
While our combos and speakers are designed to play loudly--and
clearly--enough so that you can be heard in most gigging situations,
they are not suited to playing at extreme volumes. Generating high
SPLs may require an extension cabinet like the Coda EX, Corus EX,
Ten2 EX or augmentation by a larger house system.
The instructions that follow apply to all of the products due to the many
common elements in the different units. Where there are specific
differences that are unique to one or more units, those differences are
described as necessary. The one and two channel amp heads are
described first followed by the common elements of the combo amps
(docking system, tilt mechanism, cabinet placement, etc). The
specifics of each cabinet type are then described followed by detailed
specifications of all of the models.

Plug the detachable AC power cord into the receptacle on the back of
the amp and into a wall receptacle. A power switch next to the AC input
turns on power to the pre- and power amps, illuminating a "power on"
indicator on the front panel of the amp.

All combos will work with either 100 to 120 volt, 50/60 Hz or 220 to 240
volt, 50 Hz AC power. A switch located on the rear panel selects the
appropriate voltage. Use the 115V setting for 100 to 120V operation,
use the 230V setting for 220 to 240V operation. Note that the correct
AC power cord must be used for connection to the appropriate wall
plug. If you do not have the right cord, you can buy one from an
electronics or computer store. Be sure the switch is in the correct
position for the intended application.

Inputs
Combo jacks are used for the input to each channel of their preamp.
Either an XLR or 1/4 inch connector can be plugged into this type of
jack. The 1/4 inch input has a 1 megohm input impedance that is
