Switch Modes for SH96HO, SH46 and SM80M

The SH96HO, SH46 and SM80M can be run two ways; Bi-amp or passive. In the passive mode, the connection is to pins +1

and -1. In Bi-amp mode connect the low frequency amp channel to pins 1+ and 1- of the NL4, and the high/mid channel to pins

2+ and 2-. In addition, the four 15 inch woofers on the SH96HO can be switched to present a 2 or 8 ohm load.

3.3.1 On the "Passive" setting there is an internal passive crossover. Using a SH96HO in passive mode should be viewed as a

compromise. It is sort of like paying extra for the high horsepower engine and setting a 55 MPH governor on it! In the passive

/ 8 ohm mode the low end will be a significantly lower level. This may be acceptable if the SH96HO is part of a larger cluster

where there are a number of woofers coupling together. It is also useful if there are unavoidable very long speaker runs and/ or

the amplifier is not capable of delivering the desired power into 2 ohms. For more low end in the passive mode, use the 2 ohm

setting.

3.3.2 You can also select the BIAMP setting. The BIAMP setting will allow the SH96HO to realize its full potential as a true

high output device! In the BIAMP setting, there is no crossover applied to the four 15 inch drivers! You are strongly

advised to use a crossover set to high pass of 40 Hz at 24 dB Butterworth and 600 Hz at 12 dB Butterworth. The high/mid

section is high passed at 400 Hz at 24 dB Butterworth. In the BIAMP setting you can also select between a two ohm load and

an eight ohm load for the woofers. CAUTION! If you select the 2 ohm setting, make sure that the amplifier you have chosen

can accommodate 2 ohm loads! Remember that when running a 2 ohm load the resistance of the speaker cable becomes

significant. Use the largest gauge and shortest run possible.

3.4

Impedance

On the SH96HO, in the active mode, the impedance of the low frequency section will be selected by the toggle switch, either 2

ohms or 8 ohms. The mid / high section will be 4 ohms. Since by convention the impedance of a loudspeaker is taken from the

lowest point, in the passive setting with the woofers switched to 8 ohms, the SH96HO presents a nominal 4 Ohm load. With the

woofers switched to 2 Ohms, in the passive mode the SH96HO presents a nominal 2 Ohm load.

Rigging

If you have to ask how, you probably shouldn't be doing it!

Safety Precautions

Before attempting to rig or suspend your Danley speakers, read and understand the following safety information.
