This mixing panel is a topline-mixing panel, capable of outstanding performance in combination with high-grade systems. pe2.2.0, SAFETY INSTRUCTIONS, 1) Donot expose the set to rain or water. Do not spill liquid or insert (metal) objects inside the set. Rain, water or liquid such as cosmetics as well as metal, may cause electric shocks, ‘which can result in fire or shock hazard. If anything gets inside, unplug the power cord. 2) Frayed cords and broken plugs may cause a fire or shock hazard. Do not damage the power ‘cord. When removing the power cord from wall outlet, be sure to unplug by holding the plug attachment and not pulling the cord, 3) _Donnot open the set, there are no serviceable parts inside. ‘Only qualified service technicians can service inside your set. 4) Operate the set only from a power source which is indicated on the rating label at the back of the set. 5) Donot use chemical products to clean the set. Do not use contact spray or other products in the faders. The contact spray can damage the faders. 2.3.0. INSTALLATION OF THE MIXING PANEL 1) The set can be used in every posit n. 2) Don't place the set into direct sunlight, or in a warm moist or dusty place. 3) Toavoid disturbances, do not place the set in the neighbourhood of disturbing apparatuses. FL, wire TR 1) Power switch Controls the supply of AC power to the set. One push tums the mixing panel on, a second push turns it off. It remains in a stand-by mode. 2) Power "ON" on indicators ‘These indicators light up when the power is on. 3) VU meters ‘The two VU meters indicate the PFL signal. 4) Phones output ‘Output for high level headphones monitoring. With the PFL switches (7) the connected audio ‘sources (in split mode) can be displayed without manipulating the output signal (Headphones 200-8000). 5) Phones control This bution is used to adjust the volume of the headphones. 6) Phones-select potentiometer With this potentiometer, the signal for the headphones output can be selected. When turned ‘completely to the left, the signal selected with the channel PFL-switches (7) appears on the headphones. When turned completely to the right, the mix-signal appears on the headphones. In between it results in a mix of the PFL-signal and the mix-signel 7) PFL switches With these switches you can select the different input sources that you will listen to with the headphones. p38) Input selector This switch is used to select the input signal. 9) Level adjuster ‘These controls are used to adjust input levels of the different inputs. 10) Equalizer controls This is used to regulate the degree of treble, middle and bass in the sound. 11) Channel faders Volume control for every input. 12) Crossfader With this fader you can easily fade over between channels 2 and 3 for BX-9 and channels 1-2 and 3-4 for BX-14. When the knob stands completely to the lef, the signal of channel 2 on BX-9 and channels 1 and 2 on BX-14 will appear on the output. When the knob stands completely to the right, the signals of channel 3 for the BX-9 and channels 3 and 4 for BX-14 vill appear on the output. 13) Balance The balance between the amount of sound on the left and on the right is adjusted by using this knob, When itis set to the center position, the gain is the same for the left and the right channel. 14) Master output faders Volume controls final output of mixer towards stave- or integrated amplifers. 2.5.0. CONNECTIONS A) PHONO input Phono input with a sensitivity of 2.3mV and build in RIAA correction, B) Ground If the recordplayer has a ground wire, connect it to the ground terminal C) —_LINE/LINE B input Input with a sensitivity of 220mV. To connect different apparatuses such as a CD-player, tuner, tape recorder, mini disc, cassette recorder or (HIF!) video recorder. D) Microphone input Balanced microphone input with a sensitivity of 3.8mV. Combined connector XLR + JACK. ‘The JACK connector can also be used for unbalanced microphones. E) Effects IN/OUT Input and output to connect effect apparatus to the microphone channel. If there is no plug in the JACK, the microphone channel works normally, if there is a plug inserted in the JACK, the internal link is interrupted. The sensitivity of this INOUT connection is 220mV. F) Recording outputs Outputs to connect cassette recorder, MD-recorder or (HIF!) video recorder to make recordings. G) AUX output Output for different apparatuses as integrated amplifiers, mixers or recorders. The output level is 776mV. paH) +d Master output 1 Assymetrical ‘Assymetrical output to connect a power-amplifier. The output level can be manipulated with the master fader 1 (14) from 0 fo maximum (1.88V). Master output 2 Assymetrical ‘Assymetrical output to connect a power-amplfier. The output level can be manipulated with the master fader 2 (14) from 0 to maximum (1.55V). Master output 1 Symmetrical Optional symmetrical output to connect a power-amplifier. The output level can be manipulated with the master fader 1 (14) from 0 to maximum (3.3V). Please use signal cables shorter than 1 meter for the inputs and the outputs. ING INSTRUCTIONS 1) 2) 3) 4) 5) 6) n 8) 9) ‘switch all the connected music-sources on (like CD-players, recordplayers, etc.). Then switch the power button (1) to turn the power supply on. The power indicators (2) will ight up and a few seconds later the mixing panel will be in operation, ready state. In this stage you can tum on the power amplifiers. ‘Connect the headphones to phones output (4). ‘Choose with input switch (8) the right source. ‘Switch the PFL button (7) in position ON to listen to the desired source, Tum the phones select button (6) completely to the left and turn the phones volume potentiometer (5) up to the desired position, to get the stereo signal on the headphones and the VU-meters. The PFL circuit works as a sum-system, there Is a possibilty to listen to more sources at the same time. All these operations have no influence on the outputsignal! Adjust with the level control {) the input signal so, that the red indicators of the level meters (3) ight up now and then. Adjust if necessary the quality of the sound with the equalizer (10). LOOK OUT; - The equalizer at each input is used to adjust the different sound between the sources. To correct the acoustic of the room it is probably best to use an external equalizer. Slide up the fader (11) of the choosen source. Adjust with the master (14) the volume. Ifyou like, you can mix the PFL signal, selected with the channel PFL switches (7) with the mix signal, by turing the Phones select button (6). To change the source, repeat point 3) to 6). If you like to record the mixed signal, you can simply do this by connecting a recorder to the record-connectors (F).. 27.0, SUBSONIC FILTER The two master outputs have a subsonic filter to protect the bass loudspeakers from DC and subsonic signals. This filter can not be switched off. The filter gives a reduction of 25qB at 10Hz. pS
