POST EQ takes its signal from after all equalisation, after the internal effects, and after the effects
loop, but before the master level control. Because the amplifier has stereo capabilities there is one
socket for the LEFT signal and one socket for the RIGHT signal.
The level of the DI output is fixed at a suitable level to suit the low impedance 'Mic' input on a
mixing desk. This level is dependent on the setting of the INPUT GAIN control and it is important
to have this set correctly ( see INPUT GAIN section ).
The circuit driving the DI sockets has been re-designed to produce a lower noise output than the
previous generation of amplifiers.
THE 'LINK' FACILITY
The LINK facility allows two TRACE ACOUSTIC amplifiers to be connected together to operate as
one single larger unit or for one TA200 to be connected to two TA100's as satellite units for more
power and a greater stereo spread.
To use this simply connect a jack to jack cable from one LINK socket on one unit to the LINK
socket on the other. The preamplifiers in both units will still operate independently but with their
respective MASTER LEVEL controls setting the overall volume from the speakers of both
interconnected units. All facilities on both preamplifiers will operate as normal but the amplified
sound will come from both units. ( e.g. if you plug into either preamplifier, the sound will come
form both units: if you add reverb, this will come from both, etc.).
This LINK socket is configured so that it operates as a LINE OUT as well as a LINE IN connection.
MODE BUTTON
The MODE push button selects the stereo mode that the unit is operating in.
When the button is 'IN' the MODE is MONO PREAMP STEREO LOOP. this means that no matter
which channel you plug into your sound will come out of both the RIGHT and LEFT speakers. The
EFFECTS LOOP will however operate in stereo. This will be the most common method of use of
the amplifier as the alternative MODE requires the use of a stereo instrument.
When the button is 'OUT' the MODE is SPLIT STEREO. In this mode CHANNELS 1 & 2 will come
out of the LEFT set of speakers and CHANNELS 3 & 4 will come out of the RIGHT set of speakers.
This allows a full stereo instrument for instance, to be plugged in with the LEFT signal from the
instrument into channel 1 and the RIGHT signal into channel 3, with the two sets of controls on
the LEFT and RIGHT preamps operating independently on the two halves of the stereo signal. This
includes the graphic equalisers and the effects sections e.g. it is thus possible to have reverb on the
left signal and a delay on the right.
The external effects loop will operate as before with a mono SEND combining the signals from
channels 1, 2, 3 & 4, and stereo returns.
EFFECTS SEND and RETURN
The TA200 has a parallel effects loop with stereo returns and the sockets for this are located on the
rear panel.
The EFFECTS SEND socket is for linking the preamp sound into your effects unit and the EFFECTS
RETURN sockets for returning the signal back to the preamp.
As this is a PARALLEL effects loop then you will need to RETURN just the effect signal from the
external effects unit i.e. set the wet/dry mix on the EXTERNAL unit to WET.
The signal path through the preamp is not broken when a jack plug is inserted into the EFFECTS
RETURN sockets. The EFFECTS SEND signal may therefore be used as a pre master volume LINE
OUT socket or connected to a tuner. This will allow silent tuning by turning the MASTER LEVEL
CONTROL to zero, tuning up and returning the MASTER LEVEL control back to its original setting.
The EFFECTS LOOP is located after the graphic and shape facilities and is in parallel with the
internal effects.
