Guided Tour - Main Section

4: Stereo Auxiliary Return Level (gray) - These knobs determine the input

level of signal arriving via the MPL 1502’s two stereo Auxiliary returns. Each

return is at unity gain (no boost or attenuation) when set to the “0” (2 o’clock)

position. The input signal is boosted when the knob is turned to the right of “0”

and attenuated when turned to the left of “0.” For information on how to properly

set these, see the sections in this manual entitled “Setting the Correct Gain

Structure” and “Using the Aux Sends and Returns” (pages 14 and 20).

5: Stereo Auxiliary Return Balance (white) - These knobs determine the

relative levels of the left and right input signals connected to the MPL 1502’s two

stereo Auxiliary returns. When the knob is placed at its center (detented)

position, both left and right input signals for that Aux return are at equal strength.

When moved left of center, the left input signal remains at the same strength but

the right input signal is attenuated; when the knob is moved right of center, the

right input signal remains at the same strength but the left input signal is

attenuated. When placed fully counter-clockwise, only the left input signal is

heard (panned hard left); when placed fully clockwise, only the right input signal

is heard (panned hard right). These “radical” positions are useful when you are

using a stereo Aux return as two mono returns—see the “Using the Aux Sends

and Returns” section on page 20 for more information.

When only the left input of an Aux return is connected, its Balance knob

functions as a constant level Pan control, allowing you to continuously place the

incoming signal anywhere in the left-right stereo field.

6: Headphone Level (blue) - This knob sets the level of the signal sent to the

headphone jack (see #7 below). WARNING: To avoid possible damage to con-

nected headphones (or, worse yet, to your ears!), always turn this all the way off

(to the fully counterclockwise “0” position) before plugging in a pair of head-

phones—then raise the level

slowly while listening. The Headphone Level has

no effect on the final Main Mix output level.

7: Headphone jack - Connect any standard stereo headphones to this jack (via

a standard 1/4” TRS plug) for private monitoring of the main stereo output. The

built-in MPL 1502 headphone preamp delivers 150 mw at 30 ohms.

8: Main Mix (green) - This knob determines the final output signal level—you

can think of this as being the “master fader.” Signals from all channels and

Auxiliary returns are routed here just before leaving the MPL 1502 via its left and

right main output jacks. The center detented “0” position of the knob indicates

unity gain (no level attenuation or boost). Moving the knob counterclockwise

from the “0” position (towards “-∞”) causes the signal to be attenuated (at the

very bottom, it is attenuated infinitely—in other words, there is no sound).

Moving it clockwise from the “0” position (towards “+15”) causes the signal to be

boosted by as much as 15 dB. For more information, see the “Setting The

Correct Gain Structure” section on page 14.
