T-900

The ultra-compact T-series amps stand out by their power, punch and drive. You will experience every nuance of your playing in a totally new and distinct way – completely unaltered but with lots of punch, just the way you like it. The well-balanced four-band tone control suits all musical styles with a perfect sound. The “TASTE” control allows you to emphasize the tonal characteristics of your instrument – everything between a wiry mid-boost, a bold slap and an ultra-fat Reggae or Motown sound.

Jacks for FX loop, Tuner Out, Line Out, Line In and a transformer balanced pre/post switchable DI Out with ground lift lets you connect the T-series to the outside world. T-series amps are ideal for travelling around the world thanks to their voltage switch that allows operation at 230 or 115 volts 50 – 60 Hz. Two ultra-quiet, digitally controlled fans and the tuned airflow channel in the T900 keeps the amp cool even at full power.

A great new feature for late night rehearsal is the aux-in jack, where you can connect devices such as your mobile phone, a tablet or other to jam along to your favorite tunes listening with your headphones. You don‘t even have to connect a cabinet. It‘s never been easier.
Thanks to the unique “magnet fix pins“ your T-900 is always safely connected to the amp fixing bar of your EICH cabinet. (The magnet fix pins are not available in the US)

T-series – BIG SOUND CAN BE THAT SMALL. Made in Germany.

Controls

Input: The input for your bass
CLIP: The red »CLIP« LED helps you adjust the input sensitivity of the T preamp so that the signal from your instrument best matches the preamp’s internal operating level. Turn up the »GAIN« control 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 sta- ge of the preamp is clipping somewhere and that you should either turn down the »GAIN« control. Keep in mind that excessive use of the »LO« control will raise the internal level and thus make the »CLIP« LED come on much earlier.
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 T watch the »CLIP« LED (#2). Set the »GAIN« such that the »CLIP« LED (#2) just doesn’t come up. Do not leave the volume control on your instrument 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.
TASTE: This unique feature adds to the superiority of the T’s to- nal qualities. Leave the control in the centre position if you seek a more “natural” sound. When turned to the right (clockwise) towards »RICH« the sound gets incre- asingly 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.
LINE/EFFECT MIX: Signals connected to the »LINE IN / EFFECTS LOOP RETURN« jack and the »AUX IN« 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 player, 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 prominent 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, modified, whatever) and returned to the amplifier as a whole.
MASTER: This is the overall volume control of the T and works on internal power amp. It determines the level at the »SPEAKER OUTPUTS« as well as the »LINE OUT« jack on the back panel. Furthermore you can control the level of the audio source connected to the »AUX IN« jack to blend it with your bass signal. as well as the »LINE OUT« jack.
MUTE: The »MUTE« switch should be depressed when you power up or down your T-900 – the push button switch illuminates when the function is engaged. In this mode no audio signal will be processed and heard at any output except the »TUNER« jack. 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« no matter which position the switch »POST« is in (that way your silent 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 necessary. Disengage the »MUTE« function and start to rumble – now there is signal at all outputs again.
POST: With this switch the transformer balanced »DI OUT« 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, the tone control section, and the »EFFECTS LOOP«. It is not affected by the »MASTER« control. As a reference the push button switch will be illuminated when the »DI OUT« is set to »POST«.
DI: T 1000 supplies a balanced line output signal for connecting to a house mixing board, recording console or external 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«.
GND/LIFT: There is no need to be afraid of nasty ground loops anymore. In case you will get a ground loop, please switch the »GROUND LIFT« into the »LIFT« position.

Eq

LO: This is the primary low frequency control. It allows for cutting or boosting the frequency range around 30 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. end and massive yet distinguished punch in a bass guitar. Start from the 12 o’clock position and dial in the sound you like.
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. This frequency range, when turned up, determines the body of the bass guitar signal and lets the bass kick out in a mix. Turn it counter clockwise to reduce unwanted room resonance.
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 »LO MID« control. 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 »HI MID« control gives you a great fretless sound. On the other hand, when you cut the »HI MID« range you end up with a funky slap sound of extremely high quality.
HI: The »HI« control is centred at 8 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.
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.

Outputs

POWER RECEPTACLE: Connect the supplied AC power cord to the power receptacle. 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.
PHONE OUT: This 3.5 mm stereo jack lets you connect your headphones. With the »MASTER« volume you can control both the level of your instrument and the level of the audio source connected to the »AUX IN« jack. It is possible to use your T 1000 without a cabinet, so you can just play in any situation!
AUX IN: This 3.5mm stereo »AUX IN« jack. provides the possibility to connect your mp3 player, your iphone or other external audio sources. You can control its‘ level with the »MASTER« volume to blend it with your bass signal. Please use the included 3.5mm stereo cable to connect the audio source of your choice
EFFECTS LOOP: RETURN/LINE IN, SEND These two 1/4” jacks are the serial patch points for external signal processing effects.
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 can also be used to connect various external audio sources to the T 1000 such as an MP3 player, or in order to just use the power amp of the T 1000. The »MASTER« control determines the final output level. As the »RETURN / LINE IN« jack is placed after the tone controls.
SEND: Connect the »SEND« jack to the input of the (first) external device.
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. Note that the output is muted when the »MUTE« function is engaged.
TUNER: This jack is provided for connection to an electronic tuner and is always “live” even when the T 1000 is in »MUTE« mode. This allows for silent tuning as well as providing a monitor feed which stays hot even when the house mix is muted.

MAGNET FIX PINS: On the bottom of the amp the »MAGNET FIX PINS« holds all our T-Series Amps on all our EICH Amplification 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 no problem.
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 cannot 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.
