PRODUCT DESCRIPTION – The M-LINE-200™ series has been designed with our unique DUAL OUTPUT

DESIGN, single channel, 200 watt bass guitar amplifi er. It is equipped with ¼” unbalanced instrument input, active/
passive switch with LED indicator, variable input gain, 3 switched signal pre-shape fi lters with LED indicators, 3 band
active equalization with parametric midrange, master volume control, ¼” tuner output, effects loop, balanced direct
out with ground lift switch, and a dual mode 200 watt power amplifi er with three 1/4” speaker jacks.

FRONT PANEL

INPUT – The ML-200 is equipped with a standard ¼” unbalanced input. Input sensitivity can be switched from

approximately 300 mV(Passive) to 1.25 volt(Active). The input impedance is 500k ohms. If your bass guitar has “hot”
pickups or uses an internal battery for the preamp then select the active gain setting. The precision input scaling
preamp contains a 36 Hz, 12 dB/octave high pass fi lter and an “RFI” fi lter (radio frequency interference) to eliminate
unwanted noise.

TUNER OUPUT – The ML-200 is equipped with a parallel and fully isolated tuner output. This jack is located after

the front end scaling preamplifi er, is pre-signal shape and pre-eq and may also be used to drive a separate direct
box or high impedance-recording device.

SIGNAL SHAPE – The ML-200 is equipped with 3 signal shape circuits that are factory programmed. The LOW

BOOST adds low frequency peaking gain in the 38-67 HZ band. This fi lter is especially effective when used with a 5
string bass. The MID SCOOP switch generates midrange cut, the SIGNAL ATTACK adds a peaking high frequency
boost in the 2.25-8kHz band. LED indicators are provided to visually show when each fi lter is engaged.

EFFECTS LOOP – The ML-200 is equipped with an effects loop, allowing commonly used “series” type effects

(such as compression/limiting units) or parallel effects (such as chorus or fl ange units that contain an on-board “mix”
control). The location of the effects loop is post signal shape and pre-equalization. The signal is routed through the
loop automatically if an effects unit is not plugged in. An additional feature of the effects loop is that the effects send
jack can be used as a post-signal shape, pre-EQ line output. Plugging into the effects return jack will break the signal
path and provides for a pre-EQ line input.

ACTIVE EQUALIZATION – The ML-200 contains an active 3 band equalizer with sweepable parametric

midrange control. This equalizer, similar to those found on professional sound consoles, is a very useful tool. The
low frequency EQ section is an 80 Hz, shelving curve with 15dB of cut or boost. The high frequency EQ section is
a 3.5 kHz, shelving curve with 15dB of cut or boost The parametric sweepable-mid section features 12 dB of cut or
boost with a bandwidth approximately 1 octave wide. The center frequency of this fi lter is continuously user
adjustable from 150 Hz to 2 kHz with a single control. This fi lter is typically (but not always) used to reduce or
remove offending frequencies in the instrument’s pick-up response, or boosting response to achieve a particular
voicing. Spend some time experimenting so that the process becomes creative as well as corrective.

MASTER VOLUME – The master volume control adjusts the overall volume of the amplifi er and the effects

return. Typically, best results are obtained when this control is operated between the 9:00 and 3:00 positions.

REAR PANEL

DIRECT OUTPUTS – The ML 200 is equipped with a high quality balanced direct output with ground lift switch

for pin 1. The output level is –10dB nominal line level, pin 2 hot, and the output impedance is 600 ohm. The direct
output is fully protected from mixers providing phantom power up to 48 volts.
