INPUTS Active Input Low sensitivity input for instrument with active circuitry and high output Passive Input High sensitivity input for instrument with normal output i e Passive PRE AMP MODE SELECTOR Allows access to the different pre amp modes Pre amp mode selection is achieved by depressing the relevant switch With no switches depressed the unit defaults to FET To access both FET and Tube pre amp sections depress both switches simultaneously TUBE PRE GAIN Sets the level of drive in the Tube pre amp circuit Should be used in conjunction with POST gain control to achieve the desired sound To achieve a clean sound set the PRE gain level low whilst setting the POST gain relatively high To achieve a saturated pre amp sound set the PRE gain high and the POST gain relatively low POST GAIN Sets the level of post gain See above for application PRE SHAPE Two factory set PRE SHAPES are available The MID PRE SHAPE produces an overall dip in the mid frequency responce of the amp whilst at the same time boosting the low end of the amplifier The HI PRE SHAPE boosts the upper end frequency response of the amplifier Both these PRE SHAPES can be selected simultaneously to provide a third factory pre set These pre shapes can be further modified by the units BASS MID and GRAPHIC EQ sections PRE SHAPES are footswitchable on all models except DB150C and DB150H BASS Controls the overall bass response of the amplifier GRAPHIC Nine band GRAP2. Lets look at the following example to gain an insight into how the crossover can be set up Lets assume that you have a DB400C and you wish to employ a 1x15 cabinet with a seperate power amplifier to handle the bottom end To do this you would first need to set the crossover frequency to LO Using a straight Jack connector connect the HI output to the POWER AMP IN socket 34 This routes the HI frequency signal to the internal power amplifier which is subsequently handled by the onboard speakers Using a second jack connect the LO OUT socket to the input socket of the external power amplifier connected to the 1x15 enclosurer The DB400C will handle all the MID HI frequencies whilst the 1x15 will handle all the LO end To split the signal to allow a seperate 2 x 10 enclosure to handle the HI frequencies whist allowing the onboard speaker to carry the remaining signal patch the crossover as follows SPLIT selector to HI LO OUT connected to POWER AMP IN HI OUT to input of external power amplifier connected to 2 x 10 extension cab With nothing connected to the crossover patch bay the unit defaults to full range regardless of where the SPLIT function is set DB BASS MANUAL Laney REAR PANEL FEATURES vao THIS EQUIPMENT MUST BE EARTHED o IMUIM POWER SPEAKER OUTPUT 8P 86 MAXI CONSUMPTION 300 WATTS 50 60 Hz 4 SUPPLY VOLTAGE 230V TIA amp FUSE RATING 115V T2A PREAMP OUT e
