General Description

The PAM-100 Production Audio Monitor combines two
listen-only keypanels in a single, rack-mountable unit. It is
ideal for two persons operating side-by-side in a studio or
mobile production environment. Each person can monitor
8 intercom ports and 1 auxiliary audio source. Separate
volume controls for each audio source provide complete
control over the audio mix. Each keypanel can be used as a
stand-alone monitor, using either headphones or the inter­nal speaker. Or, the output from one or both keypanels can
be transferred to a common audio mix output for connec­tion to the line input of an adjacent keypanel or similar de­vice.

Power Connection

Connect power to the universal power input module. This
module accepts 100VAC-240VAC, 50/60 Hz input. (Note:
the fuse holder is built into the module and can be ejected
by removing the power cord and then prying the holder
out. Replace fuse only with same type and rating.)

Power Up

Set the MASTER and AUX controls to minimum, and turn
on the power switch. Asterisks may briefly appear in the
alphanumeric displays. After a few moments, the displays
should show listen key assignments (or dashes where there
are no assignments). If either keypanel continues to dis­play asterisks, it cannot establish communications with the
intercom system. In this case, check the intercom cable
and connections.

The SPKR XFR switches are off at power-up, so the mix
output will also be off.

Setup Menu

Before using each keypanel, you must set the keypanel ad­dress. There are also several optional settings which
should be configured for each keypanel. Set the keypanel
address and options for each keypanel as follows:

1. On the back panel, press and release the ADDRESS
ASSIGN switch. This will activate the setup menu.
The first item in the menu, DIM ADJ, will appear in
the two left-most displays on the front of that
keypanel. Rotate the MASTER volume control to
scroll through the list of menu items (Table 1

2. To select a menu item, click the MASTER volume
control. (Press and quickly release the control.)

3. Rotate the MASTER volume control to choose from
the list of available settings for the selected menu
item.

Operation

4. Click the MASTER volume control again to select the
desired setting and return to the list of menu items.

5. Select other menu items and change settings if de­sired.

6. When all menu items are set as desired, double-click
the MASTER volume control to exit the menu system
and save the new settings. While the new settings are
being saved, the displays will briefly show asterisks.
Then normal operation will be restored. The new set­tings will be retained after power is turned off.

You can latch many keys on if desired. Tap any latched
key to turn it off. Note that you can still operate other keys
in ONE mode along with the latched keys.

MANY Mode: MANY mode gives preference to many
keys being on at once, but also lets you quickly isolate to
one listen if desired. Tap any key to latch it in the on posi­tion. The green LED will be lit while the key is on. You
can tap several keys to latch them on. To quickly isolate to
one key, press and hold that key for a moment. Both the
red and green LEDs will turn on, and all other keys will
turn off. Tap the isolated key to turn it off. When you do
this, the keys that were previously latched on will be re­stored to their on state.
