SP1200 – 5
The
PAGING MIC VOX
variable control adjusts
the ducking threshold for the paging mic. Rotate the
control clockwise to reduce the threshold. Rotate the
control counterclockwise to increase the threshold.
MIC/LINE INPUT
is provided to connect a local
microphone. This is a 3-pin Phoenix-type connector
where pin 1 is ground, pin 2 is signal high (+), and
pin 3 is signal low (–).
AMBIENT MIC
is a 3-pin Phoenix-type connector
used to connect the optional MT-3100 ambient
microphone. This microphone is used to detect the
ambient noise level in the room. The
microprocessor uses this information to adjust the
paging mic level above the ambient noise. The
ambient mic also provides an input for the optional
DSP card when it is installed.
EQ
is a 3-band equalizer with a sweepable
midrange that only affects Inputs 1-4.
LOW
is a
shelving filter that provides 15 dB of boost and cut
below 80Hz.
MID
is a peaking filter that provides
15 dB of boost and cut at the selected frequency
between 250Hz and 8kHz.
HIGH
is a shelving filter
that provides 15 dB of boost and cut above 12kHz.
AMP ADDRESS
is used to assign a unique
address to the amplifier, as well as to enable or
disable features. Switches 1-5 provide 32 separate
addresses, switch 6 determines Master/Slave
status, switch 7 enables Input 4 Priority, and switch
8 enables the optional ambient mic. Any two
amplifiers assigned to the same address can be
controlled by a single remote control when
connected together via the RS485 ports.
RS485
is a 3-pin Phoenix-type connector in the
zone that provides an interface for the SPLinker
Sound Palette Control PC application software for
centralized computer control of up to 32 zones, as well
as communication between SP1200s and SP2400s.
When two SP1200s are linked via their RS485
connectors and assigned the same AMP ADDRESS
(switches 1-5), the front panel controls and remote
controls operate both amplifiers.
REMOTE
is a 3-pin Phoenix-type connector for
the optional wired remote control (SP-41R), which
provides Input Select and Master Volume control.
EXPANSION IN/OUT
consists of two parallel 25-
pin D-Sub connectors for connecting multiple
SP1200s and SP2400s together in a serial fashion.
Any of the four program sources from any SP1200
and SP2400 can be used as the source for any of
the zones in the system by assigning it to the
expansion bus with the internal Bus Assign switches.
This is a balanced bus for the four stereo input
sources. In addition, the paging mic and paging control
signal are also provided on the
EXPANSION
bus.
LOCAL/REMOTE
is a set of eight DIP switches
used to select the input source for each input. Each
program input has two switches, one to select the
left signal source (odd-numbered switches) and one
to select the right signal source (even-numbered
switches). Move the switches up to select the local
program source, and down to select the remote
(external) program source from the
EXPANSION
bus.
PRE OUT
is an unbalanced RCA jack that
provides a line-level signal from the preamplifier
stage of the SP1200. This provides a method for
inserting an external signal processor into the signal
chain prior to the amplifier stage. The U-shaped
jumper wire should remain installed between the
PRE OUT
and
AMP IN
jacks for normal operation.
AMP IN
is an unbalanced RCA jack that accepts
a line-level signal. See
PRE OUT
above.
ZONE A OUTPUT
is a 2-pin Phoenix-type
connector that provides speaker-level signals.
The
SP1200 is shipped with the outputs configured for
70-volt operation in U.S. versions, and 100-volt
operation in European versions.
Internal jumpers are
provided to configure the amplifier for 8 ohm
systems as well. See page 14 for more information.
Connect the supplied AC linecord to the IEC AC
Socket. The AC line fuse is contained in the socket,
behind the cover located at the bottom of the
socket. Use replacement fuses only as indicated on
the rear panel.
