Using External Power
The 664 uses only one power source at a time, with external DC power taking
precedence over internal AA battery power.
To connect an external power source:
X
Plug a DC power source (not included) into the 10-18 VDC input on the
right panel.
i
Pin-4 of the locking, Hirose connector is positive (+) and pin-1 is negative (-). The
external DC supply is fully isolated (floating) from the rest of the mixer for easy
and safe interconnection with other external audio gear.
Using Battery Power
The 664 uses five AA batteries as a backup to external power. Alkaline AA bat
-
teries may be used with the 664; however, NiMH or 1.5V Lithium batteries are
the preferred type because they provide for longer run times compared to Alka
-
line batteries.
To insert batteries:
1. Unscrew the battery cap (counter-clockwise).
2. Insert five AA batteries (not included) into the battery tube. Orient the
batteries with the positive (+) end facing in and the negative (-) end facing
out.
i
With external power connected, depleted AA batteries may be removed from the
664 and replaced with new ones without affecting operations.
Voltage Ranges and Thresholds
The DC voltage indicator provides power status information based on the Ex
-
ternal DC Reference parameter, which defines the voltage range and warning
threshold for external DC power sources. Setting the External DC Reference to a
value appropriate for the type of external power being used maximizes runtime
with that source.
For instance, the indicator appears solid green when the active power source is
full or operating within the defined high voltage range. As the voltage depletes,
the indicator’s green color drops, then changes to red when the warning voltage
threshold is reached, based on the external power source’s range and threshold,
as shown in the following table:
