700RB Series

700RB Series Combos

The 700RB Series combos deliver the 700RB’s unique
features and distinct sound by using a variety of
internal speaker configurations, GK’s RBH cabinet
technology and a unique Lock N’ Roll transport
system.

Speaker Configurations:

700RB/112

One 8 Ohm 12

speaker and

one 8 Ohm horn

700RB/115

One 8 Ohm 15

speaker and

one 8 Ohm horn

700RB/210

Two 16 Ohm 10

speakers

(wired in parallel for an 8
Ohm equivalent load)and
one 8 Ohm horn

The 700RB combo electronics are identical to the
700RB head and are rated for the same maximum
power output and speaker load (380W into 4 Ohms,
and 75W into 4 Ohms).  Maximum power is achieved
by connecting one 8 Ohm extension cabinet (such as
the 210RBH,  410RBH,  or 115RBH) in addition to the
combo’s internal 8 Ohm speaker load.  To drive more
than one extension cabinet,  the combo’s internal
speaker can be disconnected by unplugging the
Speakon cable connected to the combo’s back panel.
Below is a detailed description of the maximum loads
the combos can drive.

Maximum recommended load with the

internal speaker connected:

One 8 Ohm cabinet on the 380W Amp.
One 8 Ohm horn on the 50W Amp.

Maximum recommended load with the

internal speaker disconnected:

One 4 Ohm, or Two 8 Ohm cabinets on the 380W Amp.
One or Two 8 Ohm horns on the 50W Amp.

Lock N’ Roll Transport System:

The Lock N’ Roll transport system is designed for
quick and easy rolling of the combo on flat surfaces
such as carpet, flooring, pavement, etc.  To engage the
lock and roll handle,  first move the combo into the
upright position (front perpendicular to the ground).
Next,  stand behind the cabinet and lift the Lock N’
Roll handle up with your right hand.  The handle will
lock into place after about 1 1/2 feet.  Finally, grab
the handle and tilt towards the back of the combo.
The wheels on the bottom of the cabinet will auto-
matically engage and allow smooth rolling.

To disengage the Lock N’ Roll system, first return the
combo to its upright position and stand behind the unit.
Next, with your left hand, pull the locking latch at the
base of the handle to your left, while pushing the handle
down gently with your right hand.  Finally, push the
handle down until it stops and is flush with the top of the
combo.

The 700RB Series combos are designed for maximum
setup versatility to accommodate a variety of playing
situations.  For practicing and close monitoring situa-
tions, tilt the cabinet back into its “Rock Back” position.
For stronger bass and audience projection, leave the
combo in the upright position.
