5. Install the appropriate fuse value from Table 2.
NOTE:
Use of fuses other than those listed in Table 2 will
VOID THE WARRANTY.
6. If you connected the power transformer's primary leads
for 200-, 220-, or 240-volt operation, perform steps 7, 8,
and 9 below to prevent future confusion and possible
damage to the amplifier. Otherwise, proceed with step
10 below.
7. Affix the supplied 220/240 VAC label above the power
cord and cover the 120 VAC silkscreened designation.
8. Affix the 2-amp fuse/1707C, (4-amp/
original 3.5 amp/1707C, (7-amp/1715C) silkscreened
designation.
9. Replace the standard AC line fuse with the 2-amp fuse/
1707C, (4-amp/1715C) supplied. You should find the
labels and the fuse enclosed in the plastic bag with this
manual. Refer to Table 2 for an AC fuse selection chart.
10.If you are not installing additional modules in the
mainframe right now, reinstall and secure the top cover
with the nine screws previously removed in step 2 above.
NOTE:
You can buy and install additional modules into the
mixer/power amplifier, which has six ports that you
can configure as input or output modules.
INSTALLING MODULES IN THE MAINFRAME
1. Remove and save the two screws that secure the access
panel to the top cover. Refer to figure 1 for details.
2. Plug the input or output module into one of the six channel
positions with the controls facing the rear as shown in Figure
Figure 2. Module Installation
2. Secure the module with the two screws provided.
3. Remove the blank cover panel as shown in Figure 3. Install
the selected connector assembly with the screws provided.

SHELF OR RACK MOUNTING
You may shelf mount or rack mount the mainframe. For shelf or
countertop applications, four rubber feet on the bottom of the
chassis will protect resting surfaces and provide elevation for
air flow underneath the unit. For rack or cabinet applications,
remove the four rubber feet from the bottom of the chassis. Then
install the unit in the rack with the screws and shoulder washers
provided. The unit must have 1.75" of blank space both above
and below it.
Ventiliation
The mixer/power amplifier generates minimal heat during normal
use. Although the amount of generated heat is low, make sure
the mainframe is property ventilated to prevent an excessive
temperature rise. Because the output power devices (transistors)
are sensitive to heat, you should not place the amplifier between
other heat generating equipment or in areas where the ambient
temperature exceeds 50°C (122°F).
If you mount the mainframe in an equipment rack or cabinet
with other heat producing equipment, provide adequate space
between the units. Otherwise, the equipment may become too
warm.
If a rack or cabinet contains several amplifiers, you may need
to check the ambient air temperature. To determine the ambient
air temperature, operate the system until the temperature
stabilizes. Measure the ambient air with a bulb-type thermometer
held at the bottom of the uppermost amplifier.
