JBL Control SB-2 Manuals

System Specifications: Frequency Range (-10 dB): 38 Hz-160 Hz Continuous Program Power Capacity1: 340 Watts (both inputs driven) 170 Watts (each input) x 2 Sensitivity2: 100 dB (1 W, 1 m) at corner junction (π/2 loading) 97 dB, at two boundary junction (π loading) Nominal Impedance: 8 ohms per input; 4 ohms total with both inputs paralleled. Network Filter to Subwoofer: 12 dB/oct low-pass (per input), 160 Hz Acoustic Filtering: 6 dB/oct low-pass filtering via slot-load design, 80Hz Network Filter to Satellite Outputs: 6 dB/oct high-pass (per output) Satellite Impedance: 4Ωload per Satellite Output recommended Optimum System Configuration: Four JBL Control 23 satellite speakers (two on each SB-2 satellite output) provide optimum sensitivity balance and impedance loading, resulting in full-range 38 Hz - 22 kHz system performance. Broadband impedance is 4Ωper input x 2 channels. Driver: 250 mm (10 in) long-throw with dual voice coils Enclosure Material: Particle Board Terminations: Spring terminals, accepts banana plugs. Left In, Right In, Left Satellite Out, and Right Satellite Out Installation Accessories: MTC-SB2W for installing SB-2 onto a wall or into a corner MTC-SB2C for suspending SB-2 from ceiling Dimensions (H x W x D): 394 x 585 x 343mm (15.5 x 23.0 x 13.5 in) Net Weight: 19.1 kg (42 lbs) Shipping Weight: 22.7 kg (50 lbs) 1 Continuous program is a conservative expression of the system’s ability to handle normal speech and music program material and is defined as 3 dB greater than the continuous pink noise rating (AES pink noise from 30Hz-300Hz with a 6 dB crest factor, for 100 hours continuously). 2 Sensitivity rated in the subwoofer band, from 60Hz to 90Hz, both inputs driven 1/2W each (1W total). Sensitivity with 1W to each input is 3 dB higher. JBL continually engages in research to produce improvement. New materials, production methods, and design refinements are introduced into existing products without notice as a routine expression of this philosophy. For this reason, any current JBL product may differ in some respect from its published description, but will always equal or exceed the original design specifications unless otherwise stated. Control ® SB-2 Stereo Input Dual Coil Subwoofer Key Features:
Component: 250 mm (10 in) dual voice coil transducer
Stereo inputs with high-pass outputs for satellite speakers
Slot-load vented bandpass design
Complements full-range Control Contractor Series systems
High Sensitivity: 100 dB, 1 W, 1 m The Control SB-2 provides low frequency reinforcement in subwoofer/satellite systems. The Control SB-2 is ideal for foreground music and music/paging systems in restaurants, retail establishments, theme bars, music cafes, health clubs, and other indoor applications. The unique slot-load vented design provides acoustic low-pass filtering. Compared to traditional bandpass subwoofers, the SB-2 offers superior musical clarity and bass impact. The satellite outputs are high- pass filtered, reducing overall sys- tem distortion by eliminating the need for the satellite speakers to reproduce frequencies in the low bass range. The satellites operate more efficiently, maintaining excel- lent midrange clarity and realism in music and paging. The high-pass filtering also allows a greater num- ber of satellite speakers to be paral- leled in the system by increasing the impedance the amplifier sees in the subwoofer range. The stereo inputs are 8 ohms each. The combination of the satellite high-pass filtering, the acoustic slot- load filtering and a built-in 2nd order low-pass crossover network results in smoother overall system frequency response and virtually eliminates the “muddiness” typical of other subwoofer/satellite systems by reducing frequency overlap in the low midrange.

When applied properly, small subwoofer-satellite systems – often referred to as “sub-sat” systems – can provide high fidelity sound for a wide variety of applications, such as restaurants, retail stores, hotels, music cafes, leisure venues, sports bars & lounges, fitness centers, themed applications, and many more. This guide provides recommended subwoofer-satellite configurations that work well together. In addition, the Connection Information and System Design sections provide important information for applying these subwoofer-satellite systems properly.
