The system shows a full-range source (the console) is wired to a SUB 212 subwoofer and from there the subwoofer outputs are connected to the inputs on the SAT 8. Multiple Subs: The diagram above also shows the optional use of multiple subwoofers. Multiple subwoofers can be used to increase SPL and improve the LF response of the system, by placing the subwoofers so as to smooth out the LF response at the mix / monitoring position. Please note that we recommend that you run the subs in MONO, by using the subwoofer out on the main sub and then feeding the next sub in the chain. We do not recommend running stereo subwoofers, because the LF response in the room will not be as consistent using this method. This is because electrical summation of the LF signals (as is done with bass-management using a mono subwoofer / LF signal), is a very predictable and repeatable way to get consistent LF response. LF phase issues between channels are resolved in the most absolute and accurate way - electrically. Cable and connector wiring: Use high-quality, shielded cables to connect your console, workstation or other sources to your SAT 8 / SUB 212 system. Foil-shielded cables, such as Belden 8451, 8761, or 9501 should do quite well. Other high quality cables are available and those that incorporate better shielding will yield an overall higher noise rejection, lowering your systems susceptibility to external interference. Another important tip to keep in mind when wiring your system is to route all line level cables away from the AC and other power sources, this will reduce the probability of having AC hum emanating from your monitoring system.

With the gain control on the SAT 8 set to the reference mark, a 200mV (-11. 7dBu) pink noise signal, with a bandwidth of 500 to 2kHz, will yield 90dB SPL at 1 meter. With the gain on the SUB 12 set to the reference mark, or -9dB on the SUB 15, 100mV (-13. 7dBu) pink noise signal, with a bandwidth of 40Hz to 80Hz, on one of the inputs, will yield 90dB of output at 1 meter. Because most control rooms have some gain at low frequencies a good starting point for the subwoofer level is -3dB from the reference position. If you are using multiple subs, the gain may need to be even lower than this (depends on the acoustics of the studio and the placement of the subs). For more information with regard to the controls, please see the manual that came with the SUB 12 or SUB 15, and page 6 & 7 of this manual [A Tour of the SAT 8 Amplifier & Electronics]. The SAT 8, SUB 212, SUB 12 and SUB 15 are compatible with balanced XLR connectors / cables. The total number of XLR cables needed will depend on the system configuration. However for a basic 2. 1 system, with one sub, you need a minimum of four XLR Cables. For more information on connecting your system, please see page 9 [System Signal Flow & Connections].

Since a 58 inch stand is not tall enough for accurate low-frequency measurements, a 1 meter ground plane measurement was also made and spliced in at 125 Hz on all measurements, to generate full frequency response.
