4. On the Model 74, connect the audio

level meter to the left channel of moni-

tor output A.

5. Conﬁ rm that the audio source’s left

channel is generating a steady signal

at precisely its reference level.

6. Observing the level meter, adjust

Surround A, trim pot L, to give a pre-

cise +4 dBu level at the left channel

output of monitor output A.

7. Disconnect the level meter from the

left channel of the monitor output.

8. Repeat steps 4-7 for the right, center,

LFE, left surround, and right surround

channels of Surround A.

9. Repeat steps 3-8 for Surround B,

Stereo A, and Stereo B. Obviously, the

stereo inputs have only left and right

channels, requiring only that two trim

pots be adjusted for each.

10. After the calibration procedure has

been completed, rotate the level con-

trol on the Model 75 to the fully coun-

terclockwise (minimum) position.

11. After ensuring that the Model 75’s level

control is set to minimum, return AC

mains power to the power amps or

ampliﬁ ed speakers.

The Model 75 conﬁ guration diagrams,

located at the end of this section, give

details on how each parameter is set. An

overview of each conﬁ gurable parameter

is provided in the following paragraphs.

Entering and Exiting the Conﬁ guration

Mode

A small button is located on the back of

the Model 75 Control Console, adjacent

to the 9-pin D-sub connector. Pressing

and holding this button for two seconds

places the Model 75 into the conﬁ guration

mode. In the conﬁ guration mode the Model

75’s array of buttons and LEDs no longer

perform their normal functions, but instead

allow you to observe and change many of

the operating parameters. The mute/solo

mode LEDs light alternately to indicate that

the conﬁ guration mode is active.

To leave the conﬁ guration mode and

return the Model 75 to normal operation,

once again press and hold the conﬁ gure

button for two seconds. Note that conﬁ gu-

ration changes are stored only after the

conﬁ guration mode has been exited.
