Therefore, any sound shaping that is applied within the ampli er will be heard on the DI signal as well. Both
settings should have similar general signal levels.
Neither will be affected by adjustments to the OUTPUT LEVEL control so turning up on stage will not
overload the mixing desk once it is set. All outputs will be muted if the MUTE function is used.
Different applications will determine which output(s) to use. For a pure bass sound at all times the PRE EQ
should be used. Alternatively, if all the internal processing is required then the LEFT and/or RIGHT should
be used. If in doubt choose these as the sound will be basically the same as the sound heard from the cabinet/
combo speakers. If you are not using any stereo effects then it will only be necessary to use either LEFT or
RIGHT as both will produce the same signal.
There may also be some occasions when it is desirable to use all outputs. This is particularly useful when
recording as it allows both the dry and processed signals to be recorded at the same time on to separate
channels. These can then be switched between or even mixed together at later stages of the recording session.
As they are fundamentally the same performance they will track seamlessly in pitch and phrasing.
(32) OUTPUTS – LEFT & RIGHT sockets (12 Band)
These are unbalanced 1/4” jack outputs that can be used to send the output of the preamp section to another
piece of equipment, such as a power ampli er, mixing desk or recording device. The actual level is dependant
on the setting on the OUTPUT LEVEL control which means that if these sockets are used to expand the
system with extra power amps and speakers, then the overall volume can still be set by a single control.
(33) SPEAKER OUTPUT(S)
All units feature Neutrik© Combination Speakon© and 1/4” jack sockets and most feature an additional 1/4”
jack socket depending on the speci c model. (The 715 combo only has the Combination Speakon© socket so
that the internal speaker must be disconnected to be able to connect to an extension cabinet). Units with two
power stages (e.g. AH1200-12) have separate speaker outputs for the LEFT and RIGHT channels.
These sockets are for connecting to speaker cabinets. Connections should be made before mains power is
applied to the unit.
When connecting to a speaker cabinet we recommend that the Speakon© socket is used in preference to the
1/4” jack as it provides a far superior connection. 1/4” jack sockets have been added merely for the user’s
convenience when it is absolutely necessary to use them. Please ensure that if a jack lead is used that it is
de nitely a speaker cable rather than in instrument cable; the two are very different and should not be mixed
for either application. If two extension cabinets are used with 1/4” jack leads we recommend that each cabinet
is connected back to the ampli er separately instead of using the LINK socket on the cabinet. This will halve
the current that each lead carries and provide a better connection.
Trace Elliot ampli ers are designed to deliver their rated RMS output power into 4 ohm speaker loads.
Therefore each ampli er can drive 1x 4 ohm cabinet or 2x 8 ohm cabinets (in parallel).
Driving a single 8 ohm load will deliver between 50% and 60% of the rated power. Never connect your
ampli er to a speaker load lower than the rated 4 ohms. This will result in over heating of the ampli er and it
shutting down into protect mode.
Please refer to the speci cation sheet for your cabinet for more information on its use.
