Chapter 4
– Setting Up the Power and Audio Connections
This section describes how to connect external mic- and line-level devices, and enter the proper settings to make
these connections work.
NOTE:
If you aren‟t sure how to get to the menu pages mentioned in the remainder of this user manual, refer
back to the reference in chapter 2. There, you will find the sequence key/button presses to get to it in the
section
How to get here:
.
The Fusion has factory default settings that allow the operator to power it up and immediately start recording.
When you do, it takes ~ 14 seconds to initialize and start recording. One of the defaults causes the
Home page
{
p.31
} to appear once the Fusion has finished its startup sequence. This can be changed with the
User Interface
Settings page
{
p.78
}.
Power
The Fusion can be connected to an A/C power supply. An internal or external battery can be used where A/C
power is not available.
Internal Batteries
The Fusion uses a single NP-1 style battery. All chemistries are supported, including the newer Lithium-Ions. See
the
Left Side Description
{
p.26
} for the Battery Compartment‟s location and power source warnings.
IMPORTANT:
The Fusion does not charge an installed NP-1 battery while running from external power.
External Power
The Fusion can use external power, connected to the XLR-4M, as long as it supplies the proper voltage (9.5 to 18
VDC). See the
Left Side Description
{
p.26
} for the External Power connector‟s location and power source
warnings.
Whenever the power input connector has an adequate power source connected, it is the source of power for the
Fusion.
NOTE:
If you need to run on battery power for an extended period of time, and need to record during this time,
connect an external battery to Fusion when the internal battery is low. When an external power source is
used, the Fusion automatically switches to this power source. This enables you to continue recording while
you swap out the internal battery.
Battery Display
The
Home page
{
p.31
} displays the source of power and voltage.
When the voltage of any internal or external power source drops below the user defined level, the battery
indicator changes to
red
. When the power source voltage drops below 9.5 volts, the unit shuts down.
IMPORTANT:
When the unit shuts itself „OFF‟ due to power loss or insufficient power, the audio tracks are
left in the “open” state. When it is turned back „ON‟, it automatically scans for those files and closes them.
This process can take several minutes to complete. Nothing can be done until this process has completed.
Battery Chemistry
When using newer chemistry batteries, such as Lithium-Ion, you must be aware of their unique power curve. Up
until the point where these batteries are exhausted, they show a full-charge. When using this type of battery, it is
best to test how long it normally takes for the battery to discharge fully, and use this time as your guide along with
the battery meter.
Setting the Battery Threshold
The
Battery Menu page
{
p.124
} is accessed by pressing the battery indicator on the
Home page
{
p.31
}.
The graph shown in the page displays its voltage and duration of use. The curve is unique for each battery type
(Li-Ion, NiMH). To change the threshold when the battery indicator, on the
Home page
{
p.31
}, changes to red,
perform the following:
1.
Press the
Low Battery Voltage
button
.
2.
Using the numeric keys, enter the new threshold voltage.
3.
Either press the
Low Battery Voltage
button
again, or press the
ENTER
key
on the keypad.
