Note : The block diagram of the 1000RB is printed on the rear
panel and describes the signal flow from input to output. Many
of your questions about the use and functions of the 1000RB are
explained in this diagram.
(25) FOOTSWITCH RF2
1/4'' stereo phone jack that connects to RF2, two button
footswitch, via stereo cable. This jack is wired so that TUNING
MUTE is controlled by the "tip", BOOST 2 is controlled by the
"ring", and the "sleeve" is ground.
(26) AUX IN
1/4'' phone jack that accepts a line level input. Can be used as an
effects return in a "parallel" effects loop.
(27) RETURN
Accepts line level return from external effects that are connected
in a "series loop" (such as limiters, enhancers, etc.). Plugging
into RETURN opens the connection between the 1000RB pre-
amp and power amp stages.
(28) SEND
Line level output that is post EQ and pre BOOST. Used when
sending a full range mono signal to an external device (effects or
slave amp).
(29) PRE/POST
Select the source for the XLR balanced output(32). In the "out"
position, the direct output is PRE meaning that it comes right off
the input stage, (after TUNING MUTE, before VOLUME), and
is unaffected by any front panel controls except the -10dB PAD
switch. The PRE position is used to take a balanced direct out-
put to the house PA in a live situation where the soundman wants
a signal unaffected by your VOLUME and EQ controls. In the
"in" position the balanced output is POST (comes from the last
point in the preamp, just before the master volumes) and is
affected by all the front panel controls. A POST balanced out-
put can be used for recording.
(30) BAL. LEVEL
Adjusts signal level of balanced output (32).
(31) GND LIFT
Ground lift switch that disconnects ground on balanced output
(32) to eliminate hum.
(32) Bal. Out
XLR connector with electronically balanced, low impedance
output, used to send signal to P.A. or recording consoles. Wiring
for the XLR is "American Standard" : Pin 1 is ground, pin 2 is +,
and pin 3 is-.
(33) TUNER OUT
Output that comes directly off the input stage, and can be
patched to a tuner with a shielded patch cord.
(34)&(35) SPEAKON
CONNECTORS
Deliver power to your speaker(s). Cables with Speakon
con-
nectors are recommended because of the high power/current out-
put of the 1000RB. Refer to the section titled "HOOKING UP
YOUR SPEAKERS" for recommended Speakon
cables.
(36) & (37) 1/4
''
CONNECTORS
Provided as back-up outputs. 1/4'' connectors do not have the
same power handling as Speakon
connectors, and should only
be used if Speakon
cable are unavailable.
(38) AC RECEPTACLE
Plug the power cord that is included with the 1000RB into this
receptacle.
