Samson MDR10 - Manual (Page 9)

GAIN
The MDR10’s pre-amp stage has a variable GAIN control with a range of 5 to
60dB on the MIC input and –26 to +26dB on the LINE input.
CLIP LED
The MDR10’s MIC/LINE pre-amp also includes a CLIP LED which, when illumi-
nated, indicates that the signal is peaking or overloading. To reduce distortion,
lower the GAIN control to keep this LED from staying on.
HF (HIGH FREQUENCY)
12KHz +/- 15dB shelving type The channel’s frequency response is flat when
the knob is in the "12:00" position. Rotating the knob towards the right will
boost the corresponding frequency band by 15dB, and rotating it towards the
left will cut the frequency by 15dB.
MID (CUT & BOOST)
The MID CUT & BOOST knob is used in conjunction with the MID FREQUENCY knob to create the tonal
shape in the mid-range frequency when using the mono channel’s equalizers. You can adjust the frequency
on the mid-range control with the MID SWEEP knob, and use the MID CUT & BOOST to either boost or cut
that frequency by plus or minus 15dB.
MID FREQUENCY
The MID FREQUENCY is a control enabling you enhanced capabilities in the tonal shaping of the input
channel signal. Thanks to the MID FREQUENCY control, you have a variable mid-range equalizer, allowing
you to pin point the exact frequency you want to boost or cut. The MID SWEEP has a “fixed Q” of two
octaves (the amount, or width, of frequencies around the center point that are effected by the MID CUT &
BOOST control) and can be set in a range from 100Hz to 5Khz.
LF (LOW FREQUENCY)
80Hz +/- 15dB shelving type The channel’s frequency response is flat when the knob is in the "12:00" posi-
tion. Rotating the knob towards the right will boost the corresponding frequency band by 15dB, and rotating
it towards the left will cut the frequency by 15dB.
LOW CUT FILTER
Each of the MDR10’s channels include a LOW CUT (or high pass) filter which rolls off the low frequencies
from 80Hz and below at the rate of 12dB per octave.

Controls and Functions
MONO INPUT CHANNEL SECTION
The following section details each part of the MDR10’s MONO INPUT CHANNELS including the GAIN control, CLIP LED, 3-
BAND EQ, AUX sends, PAN and LEVEL controls. The input channels one through six on the MDR10 feature high quality,
discrete transistor pre-amps providing transparency and extended dynamic range. The inputs feature a standard XLR mic
connector for microphone level signals, and a standard 1/4" phone connector, either balanced (TRS – TIP/ RING/SLEEVE)
or unbalanced (TS – TIP/SLEEVE) for line level signals.

CHANNEL EQUALIZER
The MDR10 input channels feature a 3-band, swept-mid equalizer allowing you to
adjust the high, mid, and low frequencies independently on each channel. The fre-
quency centers, range of boost or cut, and equalizer type for each band are as fol-
lows:
