increase both P O W E R A M P CONTROL 1 & 2 knobs by the same amount, so that the mix is
unchanged. These knobs can also be used to set the level of two full range speakers. So one
speaker can be used as a monitor for the guitar player or drummer and the other speaker as
the main bass cabinet. A front panel mounted P H O N E S jack is provided for practicing or as a
place to hook up a tuner. Use high quality headphones with an impedance greater than 100
when connecting to this jack. The phones jack does not interrupt the amplifiers output so a
tuner can be left plugged into this jack while playing. When using a Tip / Sleeve (mono) cable
to attach gear such as a tuner to the phones jack, insert the cable to the first click of the jack.
9. POWER / PROTECT RESET
O N / O F F switch and power indicator LED. Push the upper portion of the power switch to turn
the amplifier on. If the power indicator LED is on but no sound is coming out of the speakers,
the amp may have gone into one of its protection modes. To reset the amp, turn the power
off for one minute and then turn the amp back on. If the problem persists check for a bad
speaker cable, damaged speaker or blocked rear fan intake.

10. COOLING VENTS
These vents are for cooling the internal power amplifiers. Provide a minimum of 3" of clear-
ance for adequate ventilation. Blocking the air flow through these vents will cause the amp to
thermally protect and turn the speaker relays off. If this happens clear the obstruction first,
keep the power on and turn the guitar volume down allowing the amp to cool. The amp will
engage the speaker relays when cooling conditions return to normal.
11. EFFECTS LOOP
T h e EFF LOOP send and return jacks are used to connect external effects into the Red Line's
signal chain. The loop is located after the main EQ, compressor and noise gate and before the
graphic EQ. To use the effects loop, connect the " S N D " jack to the input of the effects unit
and connect the " RT N " jack to the output of the effects unit. The effects loop can be turned
on and off by using the F S 2 2 footswitch. When the footswitch is not connected, the loop will
default to the O N position. The status of the effects loop is indicated on the front panel by a
yellow LED marked "EFF LOOP" .
12. PREAMP / DIRECT OUT XLR
The P R E A M P XLR is a balanced output that can be configured in a number of different ways.
The LINE / DIR switch is used to select a pre or post pre amp feed. In the " L I N E " p o s i t i o n ,
the feed is post the preamp section of the Red Line amp and contains all of the signal pro-
cessing and effects that are being used. The " D I R " position is a direct feed off of the bass
guitar and is similar to using a D.I. box at the input jack. A ground lift switch is also available
on the preamp out XLR jack. Set this switch for the lowest noise when using this output. When
the GND / LIFT switch is depressed, the signal ground is lifted from this jack thus eliminating
any ground loops between the Red Line preamp out and the gear it is feeding.

13. PREAMP OUT JACKS (HI FREQ & LOW FREQ)
The PREAMP 1 & 2 OUT jacks add a lot of interconnection flexibility to the Red Line bass amp.
These jacks can be used to drive additional power amplifiers or to drive stereo or frequency
selective effects. When the amp is operating in Bi-amp mode, the LOW FREQ jack contains
only the low frequency material and the HI FREQ jack contains only the high frequency mate-
rial, as determined by the X-OVER FREQ selector knob on the front panel. When the amp is
operating in full range mode, both output jacks contain the same full range signal. Use the
front AMP 1 & 2 controls for level adjustments.
14. STEREO RETURN JACKS
The STEREO RETURN jacks are to be used as stereo effects returns or as an AMP PAT C Hj a c k .
These jacks can be used to patch external gear to the internal power amps of the Red Line
amps. These jacks can also be utilized in conjunction with the pre-amp out jacks as a full stereo
effects loop.
15. FOOTSWITCH
Connect the optional F S 2 2 footswitch to remotely control the nine band graphic EQ and the
effects loop. The first button on the F S 2 2 marked S E L E C T turns the graphic EQ on and off,
and the second button marked REVERB / EFFECTS turns the effects loop on and off. Any stan-
dard footswitch with a stereo plug will work.
16. SPEAKER OUTPUTS
The R600/R1000 amp contains two 1/4" speaker output connectors, one for each amp. The
AMP 1 (LOW FREQ) jack corresponds to the AMP 1 (LOW FREQ) knob on the front panel.
The AMP 2 (HIGH FREQ) jack corresponds to the AMP 2 (HIGH FREQ) knob on the front panel.
Multiple speakers can be attached to each of the speaker output jacks so long as the total imped-
ance is not below 2 per jack.
17. BRIDGE SPEAKER OUTPUTS
The R600 produces 600 watts (bridged mono) into a 4 load or 500 watts into an 8 load.
The R1000 produces 1000 watts (bridged mono) into a 4 load or 700 watts into an 8 load.
To activate, push the B R I D G E switch in and plug the speakers into the BRIDGE ONLY j a c k s .
18. AC CIRCUIT BREAKER
A circuit breaker is provided so that you will never have to replace the fuse. Occasionally
the circuit breaker on your amp may have to be reset if high AC voltage surges are present
or if the amp is used with excessive loads. Simply push the button to reset.
19. AC LINE CORD
All Red Line Series bass amplifiers are supplied with detachable three conductor line cords.
Make sure the cord is securely inserted into the back of the unit. Never defeat the ground-
ing pin of the AC line cord as it is there for your own protection. If you must plug into a two
prong outlet use a quality 3 to 2 prong grounded adapter.
20. SPEAKER SYSTEM / TWEETERS
Speaker systems such as the RL410T or RL210T that have tweeters with L-Pad controls should
be adjusted correctly. Be conservative or excess noise will result.
