Congratulations! You are now the proud owner of a EICH
T 1000 bass amplifier. This manual will help you get to
learn all the useful and exciting features of one of the
best amplifiers in the world.
The new EICH T 1000 is extremely small in size but very
big in sound. Composed of only the finest materials this
compact sound machine covers a broad frequency range
and impresses with a powerful punch.
Exclusive features and our new ultra-flat premium input
stage set new standards in this amplifier class. The very
effective tone controls suit all musical styles. The amps
of the T 1000 series boast a four-band tone control sec-
tion which lets you easily dial any sound you want. The
TASTE control emphasizes the tonal characteristics of
the individual instrument. Set to the centre, the control
has no effect on the signal. Turn it counter-clockwise to
filter out some ultra-low frequencies and at the same
time enhance a pronounced mid range. This is the ulti-
mate fretless tone. Turn it clockwise to soften the high
end which leads to a pumping bass sound.
Additional features like an effects loop, Tuner Out, Line
Out, Line In, two Speakon® outputs and a DI out with
Pre/Post switch prove that the T 1000 amps are extreme-
ly versatile devices. T 1000 amps are ideal for travelling
around the world due to their voltage switch which al-
lows them to be operated at 230 and 115 volts.
The result is an impressive live performance with an un-
beatable power-to-weight ratio.
The meticulous quality control during all stages of pro-
duction guarantees failsafe performance. Using only the
best components available the unique circuit design and
the professional workmanship make the T 1000 today’s
state-of-the-art in top-of-the-line bass amp manufactu-
ring.

4 GAIN
This control adjusts the basic signal level in the preamp
and thus determines it’s sensitivity and overall dynamic
characteristics. In order to best adjust your instrument’s
signal level to the internal operating level of the T 1000
watch the »CLIP« LED (#3). Set the »GAIN« and/or the
»–10 dB« function (#2) that the »CLIP« LED just doesn’t
come up.
Do not leave the volume control on your instru-
ment set too low, otherwise noise picked up along
the cable will become more prominent and thus
lower the signal-to noise ratio of the amp.
5 TASTE
This unique feature adds to the superiority of the T
1000’s tonal qualities. Leave the control in the centre po-
sition if you seek a more “natural” sound. When turned
to the right (clockwise) towards »RICH« the sound gets
increasingly fatter with lots of low-end punch, ending in
a warm, vintage-like tone. When turned to the left (coun-
ter clockwise) towards »DRY« this control adds urgent
attack and midrange growl.
The »TASTE« control allows you to quickly and
effectively soften those instruments which sound
a little harsh and scathing. At the same time bass
guitars with a muddy, booming neck pickup gain
definition by turning the »TASTE« control towards
the »DRY« position.
6 ATTACK TIME
This switch allows you to alter the attack time of the in-
cluded high-end »COMPRESSOR« (#7). When the switch
is not engaged the attack time is short which means that
the signal is compressed immediately – great for fretless
sounds. When you depress the switch, which is accom-
panied by the illuminated push button switch, the attack
time is longer. Now the transients of the signal (the very
first moments of a note) pass the circuit unprocessed re-
sulting in a hot, lively bass sound – great for rock and
funk sounds.
7 COMPRESSOR
The »COMPRESSOR« of the T 1000 gently pulls up low
notes, thus providing a great, even sustain. The more you
turn up the »COMPRESSOR« (to the right, i.e. clockwise),
the more audible is the compression effect. The level
reduction usually associated with compression is made
up by an internal automatic gain control. No matter how
much compression you apply the signal level will always
stay the same. In order to use the compressor conveni-
ently and effectively adjusting the input sensitivity (refer
to #1 through #4) is of crucial importance.
>> FRONT PANEL
1 INPUT
Plug in your shielded instrument cable into this jack. We
advise you to always turn down the volume control on
your instrument before plugging it into this jack.
2 -10
When using a bass guitar with active pickups or basically
delivering relatively high output levels we advise you to
use this function. When this switch is engaged the signal
will be attenuated by 10 dB before it reaches the »GAIN«
and TONE controls. This mode is accompanied by the
illuminated push button switch. Attenuation allows the
»GAIN« control (#4) to be used in a more subtle way by
somehow altering the taper of the pot – the »GAIN« con-
trol can be brought up to a higher position now.
If, on the other hand, the »GAIN« control must be turned
all the way up without reaching a satisfying gain range,
you better deactivate the »-10 dB« switch.
3 CLIP
The red »CLIP« LED helps you adjust the input sensitivity
of the T 1000 preamp so that the signal from your instru-
ment best matches the preamp’s internal operating level.
Turn up the »GAIN«- control (#4) while you hit the strings
of your bass hard until the »CLIP« LED starts flashing.
Now back up the »GAIN« control a bit until the LED goes
off. The flashing »CLIP« LED tells you that the input stage
of the preamp is clipping somewhere and that you should
either turn down the »GAIN« control (#4) or engage the
»-10«function (#2). Keep in mind that excessive use of
the »LO« control (#9) and »BASS BOOST« (#8) will raise
the internal level and thus make the »CLIP« LED come on
much earlier.

8 BASS BOOST
This switch, when engaged (the push button switch illu-
minates), boosts the very low frequencies around 30 Hz
by 12 dB. This adds a solid ground to the sound similar
to a valve amp.
9 LO
This is the primary low frequency control. It allows for
cutting or boosting the frequency range around 70 Hz
by 15 dB each. This frequency range represents the bot-
tom end and massive yet distinguished punch in a bass
guitar. Start from the 12 o’clock position and dial in the
sound you like.
10 LO MID
The »LoMID« control is centred at 250 Hz and offers a
cut or boost of 12 dB. The slope of this control is not as
steep as the one of the »LO« control (#9). This frequency
range, when turned up, determines the body of the bass
guitar signal and lets the bass be heard in a mix. Turn it
counter clockwise to reduce unwanted room resonance..
11 HI MID
The “HiMID« control is centred at 800 Hz and offers a cut
or boost of 12 dB, again with a more gentle slope just
like the »LoMID« control (#10). Due to the broader ranges
which are covered by these controls the sound never gets
booming or honky when you turn them all the way up.
Turning up the »HiMID« control gives you a great fretless
sound. On the other hand, when you cut the »HiMID« ran-
ge you end up with a funky slap sound of extremely high
quality.
12 HI
The »HI« control is centred at 5 kHz and offers a cut or
boost of 15 dB. Turn it up for a biting, crystal clear rock
or funk bass. Turn it counter clockwise to reduce hiss or
generally dampen the sound for a muted reggae feel.
13 HI BOOST
Depress this switch and engage a boost of 12 dB at 10
kHz. (the push button switch illuminates). This is your
switch if your strings are dead or if you are into a more
HiFi-like bass sound with silky top end.
14 LINE/EFFECT MIX
Signals connected to the »LINE IN / EFFECTS LOOP RE-
TURN« jack (#29b) and the »AUX IN« (#28) can be added
to the dry bass guitar signal according to your likings with
this »LINE/EFFECTS MIX« control.
The parallel »EFFECTS LOOP« (#29) is designed for the
connection of one or more effects devices. The »RETURN/
LINE IN« jack (#29b) can also be used to connect various
external audio sources to the T 1000 such as an MP3 play-
er, a second bass guitar, or in order to just use the power
amp of the T 1000.
The »LINE / EFFECTS MIX« is a balance control adjusting
the level of the effects sound as compared to the dry
sound of the T 1000 preamp. With the »EFFECTS MIX«
control all the way to the left the signal of the external
device, i.e. of the »RETURN/LINE IN« jack (#29b), is off. All
you hear is the dry bass signal. Turning it up a little will add
some effects to your sound. In this position (to the left of
the knob’s centre position) the effects sound is processed
in parallel with the unaffected or dry signal which enables
you to preserve the integrity of the premium tone and feel
the T 1000 is capable of delivering.
The more you turn the control clockwise, the more pro-
minent will the »RETURN« signal become (i.e. the effect)
while at the same time the dry signal will decrease. When
the »LINE / EFFECTS MIX« control is turned all the way up
to »10« the »EFFECTS LOOP« effectively becomes a serial
loop. Now the internal signal path is interrupted (rather
than just tapped), sent out to the external device(s) where
it gets processed (added with effects, modulated, modi-
fied, whatever) and returned to the amplifier as a whole.
15 MASTER
This is the overall volume control of the T 1000 and
works on the two internal power amp sections. It deter-
mines the level at the »SPEAKER OUTPUTS« (#24 - #26)
as well as the »LINE OUT« jack (#30).
Note: Each power amp features its individual »VOLUME«
control on the back panel (#25a and #26a). Do make sure
that they are turned up accordingly.

16 MUTE
The »MUTE« switch should be depressed when you po-
wer up or down your T 1000 – the push button switch
illuminates when the function is engaged. In this mode
no audio signal will be processed and heard at any out-
put except the »TUNER« jack (#31). That way you don’t
have to turn down the volume for silent tuning or when
changing instruments, thus you do without the nasty
cling which you usually hear when you unplug the jack.
The »MUTE« switch also interrupts the signal path at the
transformer balanced »DI OUT« (#18), no matter which
position the switch »POST« (#17) is in (that way your si-
lent tuning or changing instruments won’t be heard in
the PA, either).
During breaks the amp should be set to »MUTE« rather
than switched off completely. That way the internal fan
stays on and cools down the power amp circuitry if ne-
cessary. Disengage the »MUTE« function and start to
rumble – now there is signal at all outputs again.
17 POST
With this switch the transformer balanced »DI OUT« (#18)
can be selected to be a »PRE« or »POST« preamp signal. In
the »PRE« position (switch is not depressed) the »DI OUT«
signal is tapped directly after the input stage including the
»-10 dB« function (#2), if activated, as well as the »GAIN«
control (#4). In the »POST« position (switch depressed) the
»DI OUT« signal is taken after it has been processed by
the complete preamp, i.e. including the »GAIN« control
(#4), the tone control section (#8 through #13), and the »EF-
FECTS LOOP« (#14, #29). It is not affected by the »MAS-
TER« control (#15). As a reference the push button switch
will be illuminated when the »DI OUT« is set to »POST«.
18 DI
T 1000 supplies a balanced line output signal for connec-
ting to a house mixing board, recording console or exter-
nal amplifier(s) with balanced inputs. Connect a shielded
3-core microphone cable with XLR plugs to this male XLR
output. The need for an additional active DI box, which
can be pretty expensive, is obsolete. Due to the advanced
circuit design using only the best components available
the high sound quality of the »DI OUT« makes it the amp
of choice in any recording studio (you can use the T 1000’s
pre amp on its own without driving any speakers). The DI
signal can be tapped either before or after the preamp, as
determined by the switch »POST« (#17).
18a GND/LIFT
There is no need to be afraid of nasty ground loops any-
more. In case you will get a ground loop, please switch the
»GROUND LIFT« (#18a) into the »LIFT« position.
19 FS/MUTE/COMPRESSOR
Connect the optional footswitch for the T1000 to this
6.3 mm stereo jack with the cable which comes included
with the footswitch. This will allow you to switch the
functions »MUTE” (#16) and »COMPRESSOR« (#7) re-
motely. For the footswitch to work properly the »MUTE«
switch on the front panel of the amp must be »OFF«. The-
re is a red LED indicating that the »MUTE« function is
active, and likewise a blue LED for the »COMPRESSOR«
function on the footswitch. Even with the footswitch
connected the »MUTE« function can still be engaged
with the »MUTE« switch on the front panel of the amp
(#16).
20 POWER
Activating the »POWER SWITCH« will light up the switch
and make the EICH logo on the front panel (#21) illumi-
nate.
Before you turn on the amp do make sure that the
»MUTE« switch (#16) is depressed and the voltage
is correct (see #23)!
21 EICH Logo
The EICH logo in the centre of the front panel will illumina-
te blue when the “POWER” switch (#19) is turned on and
the included power strip is plugged in.

22 POWER RECEPTACLE
Connect the supplied AC power cord to the power recep-
tacle. Make sure the Euro plug is firmly inserted in the
socket. The other end of the cable should be connected
to any standard grounded AC outlet or into a power strip
of proper voltage. Before you plug in do make sure that
the voltage is correct (see #23)!
Just in case you lose the cord provided, the jack accepts
a standard 3-prong IEC cord like those found on most
professional gear and computers – you can get it at any
electronics, music or computer store.
Never (!) remove or otherwise attempt to defeat
the ground pin of the power cord in order to get rid
of a hum induced by a ground loop.
22a POWER FUSE
The T 1000 is fused for your and its own protection. If
you suspect a blown fuse, disconnect the cord, pull out
the »FUSE DRAWER« (#22a, located just below the cord
receptacle) and replace the fuse with another suitable
fuse. There should be a spare fuse in the fuse drawer.
For 230 V and 115 V units the fuse for the T 1000 must
be a 6,3 A (amps) SLO BLO 5 x 20 mm. When you’re in
a country with a standard of 115 volts set the »VOLTAGE
SELECTOR« (#23) accordingly.
If two fuses blow in a row, something is very wrong. Do
not open the unit. Refer service to qualified service per-
sonnel.
23 VOLTAGE SELECTOR
The T 1000 features a “VOLTAGE SELECTOR” allowing
you to use your amplifier anywhere in the world just by
the flick of a switch. The unit is set to 230 V when we
ship to a country in Europe.
Should you wish to use your T 1000 in the USA set the
“VOLTAGE SELECTOR” to “115 V”.
ATTENTION: Don’t forget to set it back to »230 V«
when you return home! EICH Amplification can-
not be made responsible for damages to the unit
caused by improper voltage selection. Therefore
it is a good idea to always check the »VOLTAGE
SELECTOR« before powering up the unit.
24 SPEAKER BRIDGED MODE
T 1000 sports three original Neutrik Speakon® NLJ2MD-
V speaker outputs. The wiring of the pins is as follows:
1+ = hot, 1- = ground. The one on the right (looked from
behind) is reserved for mono bridged operation. When
operating the amp in »BRIDGE MODE« care should be
taken that the minimum load is no less than 4 ohms.
24a BRIDGED MODE
Press the switch »BRIDGE MODE ON/OFF« just above
this Speakon® output until it rests in the »ON« positi-
on. In this mode neither the two »VOLUME« controls for
»CHANNEL A« (#26a) and »CHANNEL B« (#25a) nor the
»SUB-BOOST« filter (#25b) are active. The overall output
level is controlled by the »MASTER« volume control (#15)
on the front panel only. Make sure that the speaker out-
puts of »CHANNEL A« (#26) and »CHANNEL B« (#25) are
not being used.
In »BRIDGE MODE« the two internal power amps are
combined to produce 1000 watts of continuous output
power at a minimum load of 4 ohms. Be absolutely cer-
tain that the speaker cabinet(s) connected is (are) able
to handle the extremely high output power of the amp.
All EICH cabinets featuring at least 4 speakers will do
the job easily (e.g. 410L-4, 610L-4, 810L-4, 612XL-4 etc.).
When you use a speaker cabinet with a lower power
handling capacity do make sure that you operate the amp
at moderate levels only, i.e. don’t turn up the »MASTER«
control (#15) too far.
Whatever your setup is, always make sure that the spea-
ker cables are as long as necessary but as short as pos-
sible, using heavy gauge cable (we recommend at least
2 x 2.5 mm2). Do stick to speaker cables with Speakon®
connectors only, either NL2FX (two pin connector) or
NL4FX (four pin connector). The wiring of the pins is as
follows: 1+ = hot, 1- = ground. High quality EICH speaker
cables can be obtained as an option.
25 CHANNEL B
T 1000 is equipped with two power amps, »CHANNEL A«
(#26) and »CHANNEL B« (#25), which can be used simul-
taneously, each of them delivering 500 watts continuous
output power at a minimum load of 2 ohms. Each power

>> BACK PANEL
amp features one Neutrik Speakon®connector. If you
want to connect more than one speaker cabinet to the
SPEAKON®outputs you have to daisy chain one cabinet
with the next.
Just make sure that the minimum load of each power
amp is no less than 2 ohms.
»CHANNEL A« (#26) works exactly the same way as
»CHANNEL B« (#25). Thus, in total, you could connect
two cabinets with an impedance of 2 ohms each or four
cabinets with an impedance of 4 ohms each to the T
1000 simultaneously.
Both power amp channels have got their own »VOLUME«
control (#25a,26a). They allow you to set individual out-
put levels for the cabinets connected thus leaving you
with a couple of interesting options. Do make sure that
the »BRIDGE ON / OFF« switch (#24a) is in the »OFF« po-
sition – otherwise these »VOLUME« controls (#25a,26a)
are not active.
25b SUB ON / OFF
“CHANNEL B” (#25) features a unique “SUB BOOST”
filter (#25b) doing two different things simultaneously:
When this switch is depressed a low pass filter cuts all
frequencies above 200 Hz. At the same time there is a
level boost of 12 dB. This switch makes your T 1000 the
ideal amp for the use with a EICH BASS BOARD together
with a “normal” cabinet. Connect the BASS BOARD to
“CHANNEL B” (#25) with the “SUB BOOST” function
(#25b) depressed and a “normal” speaker cabinet to
“CHANNEL A” (#26) while balancing the output levels
accordingly.
26 CHANNEL A
»CHANNEL A« (#26) works exactly the same way as
»CHANNEL B« (#25) with the exception of not offering
the »SUB« filter (#25b). Thus you can connect one or two
speakers (by daisy chaining them) with a total impe-
dance of 2 ohms. The output power rating is 500 watts.
»CHANNEL A« (#26) and »CHANNEL B« (#25) can be ope-
rated simultaneously.
»CHANNEL A« (#26), just like »CHANNEL B« (#26), fea-
tures its own »VOLUME« control (#25a,26a). It allows
you to adjust individual output levels for both channels
and thus the cabinets connected. Do make sure that the
»BRIDGE MODE ON / OFF« switch (#24a) is in the »OFF«
position – otherwise this »VOLUME« control is not ac-
tive.
27 PHONE OUT
This 3.5 mm stereo jack lets you connect your headphones.
With the »MASTER« volume (#15) you can control both the
level of your instrument and the level of the audio source
connected to the »AUX IN« jack (#28). It is possible to use
your T 1000 without a cabinet, so you can just play in any
situation!
28 AUX IN
This 3.5mm stereo »AUX IN« jack (#28). provides the pos-
sibility to connect your mp3 player, your iphone or other
external audio sources. You can control its‘ level with the
»MASTER« volume (#15) to blend it with your bass signal.
Please use the included 3.5mm stereo cable to connect the
audio source of your choice.
29 EFFECTS LOOP
RETURN/LINE IN, SEND
These two 1/4” jacks are the serial patch points for ex-
ternal signal processing effects.
29b RETURN/LINE IN
Connect the output of the (last) external device to the
»RETURN« jack.
Always use high quality shielded instrument cables for
connecting to and from external devices. Keep the cables
as short as possible.
If you notice crackling distortion when using external
effects, either the batteries of the stomp box have run
out, or the send level of the amplifier is too high for the
processor’s input stage. In this case you better connect
the device between bass guitar and amplifier.
The »RETURN / LINE IN« jack (#29b) can also be used

Connect the »SEND« jack to the input of the (first) exter-
nal device.
30 LINE OUT
This jack provides a line level signal for connection to
a separate power amp, PA mixing console or recording
equipment. The volume of the signal is controlled by the
»MASTER« control (#15). Note that the output is muted
when the »MUTE« function (#16) is engaged.
31 TUNER
This jack is provided for connection to an electronic tuner
and is always “live” even when the T 1000 is in »MUTE«
mode (#16). This allows for silent tuning as well as pro-
viding a monitor feed which stays hot even when the
house mix is muted.
32 MAGNET FIX PINS
On the bottom of the amp the »MAGNET FIX PINS«
holds all our T-Series Amps on all our EICH Amplifica-
tion cabinets. The ultra-strong magnets holds the amp
safe because all Cabinets are equipped with the »AMP
FIXING« system. Even inclination angle above 45 ° are
