SONOSAX SX-PR - Manual (Page 3)

MASTERS Rotary faders to control left and right output
INDICATORS The two rows of LED indicate the master output level (switch DIRECT) or the input level of the tape
return (switch TAPE).
0 dB on the level meter correspond to +6dBu on the output.
It is possible to select Peak or VU ballistics by internal jumpers (factory setting = Peak). Should you
wish the level meter to follow the headphone switch (MONO/STEREO; L/R) can you have this by
another jumper setting (factory setting = always output level). For more information see chapter
" Settings ", page 9).
Activating the switch Bat-Test indicates the average voltage per battery cell on the left channel LED
row.
ON (LED) Indicates Ready to operate.
BATT LO (LED) Lights up when average voltage sinks below 1 Volt.
LIMIT (LEDs) Indicates limiter activities for each channel (or parallel if linked).
Slate Microphone Small Electret microphone, located between ON and BATT LO indicators.
Top pannel
MONITOR In this area you find all the necessary switches and buttons for the headphone monitoring.
(MONO)
STEREO
MONO
Toggel switch with three positions:
Middle position provides the stereo signal
MONO provides mono
(MONO) provides mono signal as long as the switch is maintained in this
position.
L/STEREO/R Toggel switch with three positions:
Depending on switch position the stereo signal or left or right channel signal is
provided on both headphone output channels.
TAPE/DIRECT Toggel switch with two positions:
Select master output or Tape return. An internal setting makes it possible to
have the level meter following the switch. (See chapter " Settings on page
XX ").
LEVEL Rotary switch with 6 steps for listening level
(OSC)/OFF/OSC Toggle switch with 3 positions:
Switches the built-in oscillator (1kHz) ON or OFF and sends it to the master output. (OSC) Oscillator is
activated as long as the switch is maintained in this position. The output level is +6dBu (Meter = 0dB),
when master pot on 0dB.
(MIC)/OFF/MIC Toggle switch with three positions:
The built-in slate microphone is activated as long as the switch is held in position.
LIMITER
ON/OFF/LINKED
Toggle switch with three positions:
Switches the built-in limiters in the left and right master output ON or OFF. The use of these high
quality limiters helps you to avoid the overload of the output or your recorder input. Where stereo
balanced limiting is needed use the position " LINKED ".
POWER
EXT/OFF/BATT
Toggle switch with three positions:
Switches the unit ON or OFF. In position BATT the power is drawn from the three C-Cells (dry cells or
NiCd) in the battery compartment.Position EXT is set when using external power source.
(BATT TEST)
ECO
BARGRAPH
Toggle switch with three positions:
In position BATT TEST the upper level meter indicates the average voltage of the cells. Position
ECOnomy saves battery by lighting two LEDs only on each row of the meter instead of the complete
bar as in position BARGRAPH.
Battery housing Only 3 C-Cells are enough to power the SX-PR4.
Make sure the cells are positioned as indicated on the unit. Note that the autonomy of NiCd is
substantially shorter than of dry cells.
It is possible to recharge NiCd cells in the SX-PR when using the external mains supply. To do this
you have to correctly set the internal switch to " ON " (older units have to add a charging jumper).
Recharging is possible while using the unit or when turned off.
Attention: Do not charge dry cells ! This may be dangerous and distroy the SX-PR. Always take
them out if your unit's internal switch is set for recharging when using the external AC/DC
adapter.
