1. XLR INPUT 0dB / -10dB Dip-Switches - These dip-switches control

the 10dB input “pad” on the 80Hz Input. With both dip-switches

in the UP position, the -10dB pad is in circuit. With both switches

in the down 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 8 Feature Overview].

2. 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 8 Feature Overview] and page 9 [System Signal Flow &

Connections] for more information.

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 -10dB input pad, this allows

for a range of -22dB to REF. Please refer to page 5 for more

information [SAT 8 Feature Overview].

4. Bafﬂe Compensation Dip Switches - The SAT 8 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 “UP” 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. For more information see page 5 [SAT 8 Feature Overview]

and page 14 [Measurement Data].

5. Individual Driver Level Controls - The SAT 8 includes +/- 3dB

of individual driver level adjustments, in 1dB increments. The

switches are additive, so in order to increase the level of a driver

by 3dB set both the 2 and 1dB switches to the UP 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 8. For more information please see page 5 [SAT 8

Feature Overview] and page 14 [Measurement Data].

6. Rear Power LED - This power LED indicates the SAT 8 is powered

ON.

7. Ampliﬁer Heatsink - The heatsink provides essential cooling to

the ampliﬁers inside the SAT 8. 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 8.

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, please also conﬁrm the proper fuse

is installed [see number 10].

9. Power Switch - Controls the power to all the three ampliﬁers and

all internal electronics.

10. FUSE - Replace with same rating and type for your local voltage

rating. For 115V applications use a 6 Amp T 250V and for 230

Volt applications use a 5 x 20mm, 3.16 Amp, T 250V fuse (“T” =

Time Delay or SloBlo type fuse).

11. IEC RECEPTACLE - Check voltage selector switch before

connecting power. Connect to 115 Volt AC / 60Hz power source,

rated for 400 WATTS or 230 Volt / 50Hz rated for 400 WATTS.
