Tuner Socket (12 Band); Balanced Di Outputs-Left, Right, Pre Eq Xlr Sockets (12 Band) - TRACE ELLIOT 12 Band Serie Manual De Usuario

➢ Overdrive/Distortion just on high frequencies: connect HI PASS SEND to input of
Overdrive/Distortion unit, connect MONO RETURN to output of Overdrive/Distortion unit.
Switch to PARALLEL, LOOP LEVEL to 12 o'clock. Set effect as desired. Switching LOOP on
will apply Overdrive/Distortion to the upper frequencies while keeping the low end clear.
➢ Envelope Filters: try using an envelope filter triggered from the HI PASS SEND, try again
triggered from the LO PASS SEND, this will produce different results. Got two envelope
filters? Try triggering one from HI PASS, the other from LO PASS, bring their outputs back
into LEFT and RIGHT and set one to filter up the other to filter down, weird enough? Now
switch on the VALVE drive circuit to really give them something to get their teeth into!
➢ Inserting external audio source: connect outputs of external unit (synth, CD, sequencer, drum
machine, etc.) into LEFT and RIGHT RETURN. Set to PARALLEL with the LOOP LEVEL at
12 o'clock. Switching the LOOP on will mix the external audio source with the bass signal.
Use the output level on the external source to balance the two.
➢ Effects Loop as a crossover (requires unit with two power amplifiers): connect patch leads
from HI SEND to RIGHT RETURN and LO SEND to LEFT RETURN. Set to SERIES with
LOOP LEVEL at 12 o'clock. With LOOP selected all left outputs will produce the low
frequencies, all right outputs the high frequencies.
➢ Triggering of external devices such as synth: connect the LO PASS SEND to input of device
to be triggered. Signal will be present at all times and will have high frequency content removed
therefore making it easier for the external device to determine the fundamental frequency.
These are just a few ways in which the EFFECTS LOOPS connections can be used.
configurations are only limited by the equipment that is available and your imagination.
Stereo/Mono?
The 12 Band preamp is stereo from the EFFECTS LOOPS through to the LINE OUTS. Units with
two output stages (e.g. AH1000-12) remain stereo through to the speaker outputs. Units with one
output stage (e.g. 1215, 1210) have the two channels mixed into mono at the final preamp stage.
Therefore although the signal from the speaker output will be mono, the DI and LINE OUTs retain
stereo separation for recording or sound reinforcement purposes.

(30) TUNER socket (12 Band)

This is an output for connecting to a tuner. The signal here is a buffered version of the input signal
before any processing has been applied. Simply connect a 1/4" jack lead from this socket to a tuner
and you will be able to tune up easily any time without any degradation to the tone. (As the actual
level is determined by the INPUT GAIN, if you wish to tune up silently use the MUTE function,
which mutes all outputs except TUNER, rather than adjusting the INPUT GAIN.)
(31) BALANCED DI OUTPUTS – LEFT, RIGHT, PRE EQ XLR sockets (12 Band)
These are separate low impedance balanced outputs for connecting direct to a stage box or mixer for
live or studio use. This gives the engineer a strong, clean signal without any overspill from other
instruments. The XLR socket is wired as normal: pin 1 = Ground, pin 2 = Signal +, pin 3 = Signal –
The PRE EQ output is taken before any EQ is applied, therefore a higher level, buffered, version of
the input signal. The LEFT and RIGHT outputs are taken after the PRE SHAPE, VALVE,
GRAPHIC, COMPRESSOR and EFFECTS LOOPS, but before the OUTPUT LEVEL control.
Therefore, any sound shaping that is applied within the amplifier will be heard on the DI signal as
well. Both settings should have similar general signal levels.
