1. 40Hz (Extended Range) XLR INPUT 0dB / -10dB Dip-Switches
- These dip-switches control the 10dB input “pad” on the 40Hz
Input. With both dip-switches in the LEFT position, the -10dB pad
is in circuit. With both switches in the RIGHT position, it is out of
circuit. Max input in the 0dB position is +14 dBu, in the -10dB
position it is +24 dBu. Refer to page 5 for more information [SAT
6.5 EXR Feature Overview].
2. 40Hz (Extended Range) XLR INPUT - This XLR input should be
connected to a full-range source. This input is electronically
balanced. Do not connect more than one source to this input.
Refer to page 5 [SAT 6.5 EXR Feature Overview] and page 9
[System Signal Flow & Connections] for more information.
3. 80Hz XLR INPUT 0dB / -10dB Dip-Switches - These dip-switches
control the 10dB input “pad” on the 80Hz Input. With both dip-
switches in the LEFT position, the -10dB pad is in circuit. With
both switches in the RIGHT position, it is out of circuit. Max input
in the 0dB position is +14 dBu, in the -10dB position it is +24
dBu. Refer to page 5 for more information [SAT 6.5 EXR Feature
Overview].
4. 80Hz XLR INPUT - This XLR input should be connected to a bass-
managed output with a 12 per octave 80Hz high-pass filter, such
as the bass-managed outputs on the SUB 15 Universal, SUB 212,
SUB 12, or BMC. This input is electronically balanced. Do not
connect more than one source to this input. Refer to page 5
[SAT 6.5 EXR Feature Overview] and page 9 [System Signal Flow
& Connections] for more information.
5. 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 -10dB input pad, this allows
for a range of -22dB to REF. Please refer to page 5 for more
information [SAT 6.5 EXR Feature Overview].
6. Baffle Compensation Dip Switches - The SAT 6.5 EXR includes four
primary baffle compensation settings, each of which reduces the
MF to LF “bump” that typically results from mounting a speaker
in a baffle wall. To select a specific setting, put the individual dip
switch into the “LEFT” position. For additional flexibility, baffle
compensation switches can be used in combination.
The amount of compensation needed is dependent on room
acoustics, along with the size and type of baffle wall. The only
way to accurately determine the amount of compensation needed
is to use a high resolution acoustic analyzer, such as MLSSA,
TEF, etc.
7. Tweeter Level Controls - The SAT 6.5 EXR includes +/- 3dB of
tweeter level adjustments, in 1dB increments. The switches are
additive, so in order to increase the level of the tweeter by 3dB
set both the 2 and 1dB switches to the LEFT position. We highly
recommend that you only change these settings, from the “flat”
position, as a last resort and only after doing proper acoustics
treatment of the room and ensuring proper placement of the SAT
6.5 EXR. For more information please see page 5 [SAT 6.5 EXR
Feature Overview] and page 14 [Measurement Data].
8. Rear Power LED - This power LED indicates the SAT 6.5 EXR is
powered ON.
9. 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, please also confirm the proper fuse
is installed [see number 10].
10. Power Switch - Controls the power to the two amplifiers and all
internal electronics.
11. FUSE - Replace with same rating and type for your local voltage
rating. For 115V applications use a 2.5 Amp T 250V and for 230
Volt applications use a 5 x 20mm, 1.25 Amp, T 250V fuse (“T” =
Time Delay or SloBlo type fuse).
12. IEC RECEPTACLE - Check voltage selector switch before
connecting power. Connect to 115 Volt AC / 60Hz power source,
rated for 375 WATTS or 230 Volt / 50Hz rated for 375 WATTS.
13. Amplifier Heatsink - The heatsink provides essential cooling to
the amplifiers inside the SAT 6.5 EXR. This heatsink is oversized
and designed to be effective in both vertical and horizontal
orientation, as long as proper air circulation is provided. Please
ensure that proper air circulation is available for cooling. This is
especially important when baffle mounting the SAT 6.5 EXR.
