5. A Tour of SAT 5 MK II
Amplifier & Electronics
1. XLR INPUT 0dB - This XLR input should be connected to a bass-
managed output, such as the bass-managed outputs on the SUB
8 / Universal, SUB 12, SUB 15, or BMC (see item 4 on this page
for additional important information). This input is electronically
balanced. Do not connect more than one source to this input. With
the gain control on the SAT 5 MK II set to the reference mark, and
the input attenuator set to the +24dBu setting, a 200mV (-11.7dBu)
pink noise signal, with a bandwidth of 500 to 2kHz, will yield 90dB
SPL at 1 meter. Refer to page 9 [System Signal Flow & Connections]
for more information.
2. 12dB Input Attenuator Switch - This switch controls the 12dB
input "pad" on the XLR Input. With this switch in the +24dBu
position, the -12dB pad is in circuit. With this switch in the
+12dBu position, it is out of circuit. The 12dB input attenuator, in
combination with the gain control (Item 3 on this page), allows the
user to adjust the gain from REF (200mv of 500 to 2kHz pink noise
= 90dB SPL @ 1M) to -24dB.
3. GAIN - This trim pot is a continuously variable gain control, with a
range of -12 to REF (200mV of 500 to 2kHz pink noise = 90dB SPL
@ 1M). In combination with the -12dB input pad, it allows for a
range of -24dB to REF.
4. High Pass Switch: The SAT 5 MK II includes a user selectable
high pass filter network. This filter network can be switched "IN"
or "OUT" of circuit. When the SAT 5 MK II is used in a 2.1 system
configuration, with the SUB 8 / Universal, this switch must be in the
"IN" circuit position. If the SAT 5 MK II is used with the SUB 12,
SUB 15 or BMC, this switch must be in the "OUT" position. This
is because the SUB 8 / Universal, which is part of the ProDesk™
system, does not include the requisite high pass filter networks,
which are included in the bass-managed outputs on the BMC, SUB
12 and SUB 15. Lastly, when using the SAT 5 MK II with the SUB 8
Universal, also confirm that the VARIABLE / BLUE SKY SAT 5 switch
on the back of the SUB 8 Universal is set to the "BLUE SKY SAT 5"
position.
5. Power LED - This power LED indicates the SAT 5 MK II is powered
ON.
6. Amplifier Heatsink - The heatsink provides essential cooling to
the amplifiers inside the 6.5 MK II. Please ensure that proper air
circulation is available for cooling.
7. IEC RECEPTACLE / FUSE HOLDER - Check voltage selector switch
before connecting power to the IEC connector. Connect to 115
Volt AC / 60Hz power source, rated for 85 WATTS or 230 Volt /
50Hz rated for 85 WATTS. Replace fuse with same rating and type
for your local voltage rating. For 115V applications use a 2 Amp T
250V and for 230 Volt applications use a 1 Amp T 250V fuse ("T" =
Time Delay or SloBlo type fuse).
8. Voltage Selector Switch - This switch can be set to either 115
Volts or 230 volts. Prior to powering this unit, please confirm that
the Voltage selector switch has been set to the correct voltage
setting. If you are unsure of the type of power that is supplied to
your studio, consult your product dealer or local power company.
If your changing the Voltage, also confirm the proper fuse is
installed [see number 8].
9. Power Switch - Controls the power the internal amplifiers and all
internal electronics.
