BC112 Pro

The BC112pro combo is driven by power, punch and drive. With it’s 500 Watts you will experience every detail 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 emphasise 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 BC112pro to the outside world. The BC112 is ideal for travelling around the world due to their voltage switch which allows them to be operateded at 230 or 115 volts 50 – 60 Hz.
The BC112pro combo is fitted with our newly designed EICH TE12D-8 12” bass speaker chassis that works in meticulously calibrated enclosures to deliver an impressive bass. For optimum damping of unwanted resonances our housings are made with support bracings and dampened with acoustic foam.
The combo features the new 4” CT1 tweeter with a ceramic-magnet system. In a coupled volume the tweeter convinced on one hand with his deep starting frequency, on the other hand, with its very flat frequency response and offers far beyond 10 kHz at astounding sound pressure for silky highs.
All combos have an additional Speakon® combo connector for operating an additional cabinet. The internal speaker can be selectively switched off. At the “Rehearsal Section” a headset can be connected at “Phone out” and trough the “AUX-In” a music signal can be fed.
The BC112pro can be tilted in to a monitor position by inserting a stainless steel rod, which is located at the bottom of the combo.

Controls

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.
CLIP
The red »CLIP« LED helps you adjust the input sensitivity of the BC112Pro 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 stage 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 l 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 BC112Pro 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 BC112Pro tonal 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 increasingly fatter with lots of low-end punch, ending in a warm, vintage-like tone. When turned to the left (counter 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
MASTER
This is the overall volume control of the BC112Pro and works on internal power amp. It determines the level at the “INTERNAL and External SPEAKER OUTPUTS” and 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.
MUTE
The »MUTE« switch should be depressed when you power up or down your BC112Pro the 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 balanced »DI OUT« no matter which position the switch »POST« and »GND/LIFT« is in (that way your silent tuning or changing instruments won’t be heard in the PA, either). 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 »GAIN« control. In the »POST« position (switch illuminates when the function is engaged) 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.
DI
The BC112Pro supplies a transformer 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 BC112Pro pre amp on its own without driving the Internal 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.
Power
At the risk of stating the obvious, this switch is used to turn the BC112Pro on and off. Before you turn on the amp do make sure that the »MUTE« switch (#10) is depressed. Provided the included power cord is plugged into the »POWER SOCKET« on the back panel (#14) and into an appropriate wall socket, the »POWER SWITCH« (#13) on the front panel will illuminate when the switch is turned on, no matter what positions other switches are in. The amp is OFF when the »POWER SWITCH« is depressed – the »POWER SWITCH« will no longer illuminate.

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 bottom 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.

Outputs

EXTERNAL SPEAKER OUT
BC112Pro sports one Neutrik Speakon® Combo NLJ2 MD-V external speaker output. Just make sure that the minimum load of the external speaker is no less than 8 ohms. Whatever your setup is, always make sure that the speaker cables are as long as necessary but as short as possible, using heavy gauge cable (we recommendat 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). No matter which plug you use the “hot” wire must be connected to pin “1+” and the “cold” wire to pin “1-“. This Speakon® Combo socket is also able to handle a 1/4“ jack. High quality EICH speaker cables can be obtained as an option.
INTERNAL SPEAKER ON/OFF
The internal speaker on/off switch allows a silent rehearsal with headphones. It is also possible to use an external cabinet and thereby turn off the internal speaker. In this case, the connected speaker has an impedance of at least 4 ohms. If the internal speakers of the BC112Pro switches on, the impedance of the connected cabinet must be at least 8 ohms.
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.
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 BC112Pro without a cabinet, so you can just play in any situation!
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 BC112Pro such as an MP3 player, or in order to just use the power amp of the BC112Pro. 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 BC112Pro 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.
POWER RECEPTACLE
Connect the supplied AC power cord to the power receptacle. Make sure the IEC 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 #15)! 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 one 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.

POWER FUSE
The BC112Pro is fused for your and its own protection. If you suspect a blown fuse, disconnect the cord, pull out the »FUSE DRAWER« (located just below the cord receptacle) and replace the fuse with another suitable fuse. There should be a spare fuse in the fuse drawer.. When you’re in a country with a standard of 115 volts set the »VOLTAGE SELECTOR« accordingly. If two fuses blow in a row, something is very wrong. Do not open the unit. Refer service to qualified service personnel.
VOLTAGE SELECTOR
The BC112Pro 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 BC112Pro 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 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.
