CAUTION: To reduce the risk of electric shock, do not remove the cover
(or back). Refer to qualified personnel.
WARNING: To reduce the risk of fire or electric shock, do not expose
this appliance to rain or moisture.
The lightning flash with arrowhead, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electrical shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating maintenance (servicing) instructions in the literature accompanying the appliance.
IMPORTANT SAFETY NOTE
Before connecting a new component such as the ICBM to your audio or home theater system it is always good practice to make certain that all components are turned off, and preferably unplugged from their AC power source. Many modern electronics products feature automatic turn-on circuits that may be activated during an installation, causing the potential for damage to electronic components and/or speakers. [. . . ] Even if you use delay for Dolby Digital or DTS, you won't get it for DVD-Audio or SACD. Thus, deactivating delay will probably have a very small effect on the sound quality of your system. The second option is appropriate if your surround speakers are eight or more feet closer to the primary listening position than the front speakers. In that case you should use the delay settings provided in the receiver or processor. Delaying signals before they reach the bass management circuitry could cause some cancellation effects in the bass, but bass response in a room is typically very uneven, anyway, so it's unlikely you'll notice this effect. Turn to page 13 for the operating instructions.
Using the ICBM in a stereo system with a subwoofer
To use the ICBM in a stereo system, your system must have either a separate preamp and amplifier, or a preamp output/power amp input on your integrated amp or receiver. We recommend using high-quality, brand-name, shielded audio interconnect cable.

For systems with separate preamplifiers and power amplifiers:
Step 1a Connect your preamp to ICBM.
Connect the left and right channel outputs on your preamp to the left and right inputs on the ICBM.

Step 2a Connect the ICBM to your amplifier.
Connect the ICBM's left and right outputs to the left and right inputs of your amplifier.
For receivers with preamp outputs and main inputs:
Step 1b Connect your receiver to ICBM.
First, remove the jumpers that connect these jacks and save them for future use should you use the receiver at a later date without the ICBM. Then, connect thhe left and right preamp outputs to the left and right inputs on the ICBM.
Step 2b Connect the ICBM to your receiver.
Connect the left and right outputs of the ICBM to the "main in" jacks on the receiver.
For both options:
Step 3 Connect your subwoofer(s).
If you're using a single subwoofer, connect either of the ICBM's subwoofer outputs to the subwoofer's line-level input. Use the subwoofer's "bypass" input or control setting if it has one; if not, use the highest crossover frequency setting your sub provides. If you're using two subwoofers, connect the left subwoofer to the ICBM's left subwoofer output, and the right subwoofer to the ICBM's right subwoofer output.
Step 4 Plug in the ICBM's AC adapter.
Connect the small plug at the end of the cord from the ICBM's external transformer/power supply into the matching jack on the ICBM's rear panel. (Due to the low current draw of the ICBM you may safely connect it to the rear panel outlets on a processor or receiver so that it turns on automatically with your system. Now we'll explain how to set the ICBM's controls.
The Basic Principles of Bass Management
If you were to run your entire system "full range" (i. e. every speaker set to "large, " so they all get everything from 20Hz to 20kHz), the smallest speakers in your system would receive deep bass signals. As a result, you wouldn't hear much of the bass, because small woofers and cabinets can't reproduce it. Any deep bass you did hear from a small speaker would likely sound distorted. Bass management is the circuitry you use to direct low frequencies to the speakers best able to handle them. For example, a bass management system can extract low frequencies out of small surround speakers (that aren't designed for deep bass), and either re-direct the bass to a large pair of tower speakers in the front--or send it to a subwoofer.

Owner's Manual Principles of Bass Management
Bass management circuitry is sometimes called a "crossover, " and the point at which it divides the bass from the other frequencies is called the "crossover point. " You'll find bass management circuitry built into all Dolby Digital receivers and pre-amp/processors, and into all DVD players which contain onboard internal 5. 1-channel Dolby Digital decoders. Bass management circuitry not only gathers in the low frequencies from all channels and redirects them to where they can be easily reproduced, It also handles the . 1 channel. The . 1 channel (in a 5. 1-channel soundtrack ) is actually a special, additional bass track on Dolby Digital, DTS, DVD-Audio, and multichannel SACD discs. In many cases, extra deep bass is recorded onto this . 1 track, which is normally routed to a subwoofer. But in systems that do not have a subwoofer, you will not hear the . 1 bass unless you use bass management circuitry to re-route the bass into the other speakers in the system.
So why do you need an ICBM?
Most of today's DVD-Audio players, and some of today's multi-channel SACD players, do not have bass management when you're playing DVD-Audio or SACD discs. [. . . ] If your system sounds good with most discs, but certain discs sound too bassy, try lowering the LFE level for those discs. This control does not affect the bass content of the other channels, so it will not affect the fundamental balance and tonal quality of your system.
Setting the Subwoofer Level control
This control lets you fine-tune the balance of your subwoofer with your other speakers. You can boost the subwoofer by up to 9 dB, or completely turn it down. You may find that with certain program material, kicking the subwoofer up a couple of decibels (or pulling it down a few dB) gives a more satisfying effect. [. . . ]
