Note: For those amplifiers with IOC (Input-Output Comparator) the channel two IOC indicator will illuminate when the unit is operated in Parallel-Mono. Note: CE Contractor Series (CH/CL Series) CP660, D Series and K Series amplifiers cannot operate in a Parallel-Mono mode.

Connect the speaker leads across the two red binding posts, using channel one binding post as the + (hot) connection or on CE's with Speakons across pins 1+ and 2+ on the channel one output.

The input impedance of Crown amplifiers is high enough that paralleling multiple inputs together is not a problem. Using a standard "Y" cable works wonderfully. Without using a "Y" cable, the procedure is different depending upon the Crown amplifier used. Com-Tech amplifiers have barrier block inputs that make it easy to tie two or more channels together. With Macro-Tech amplifiers the 1/4" inputs are in parallel with the inputs of the PIP-FX.

No, you can not bridge a mono amp because there is nothing to "bridge" to — whatever impedance load you present to amplifier is the actual load that it sees. This differs from a multichannel amp in that when you bridge two channels together, you halve the load presented to them (for example, 2 4-ohm woofers wired in parallel and bridged to a stereo amplifier is "seen" as a 1-ohm load to that amp).

Generally, the deciding factor to this dilemma is the total speaker load impedance you wish to drive. With Micro-Tech and Macro-Tech amplifiers you would want to use Bridge Mono to get the most power available when driving 8 or 4-ohm loads (one or two 8 ohm speakers). With a Power-Tech or Com-Tech amplifier you need to stay at 8 ohms or greater. Parallel Mono can be used when driving lower impedance loads. A one-ohm load can be driven Parallel Mono with a Micro-Tech or Macro-Tech.

Because mono amps tend to be Class D amplifiers, they are a good choice for powering subwoofers — Class D amplifiers have a high power-to-heat ratio and excellent efficiency, which are exactly what you want when dealing with power-hungry low frequency signals. Most mono amplifiers are designed to run at 2 ohms; some are even 1-ohm stable. Multichannel amplifiers, on the other hand, are typically designed to work with a 4-ohm load.

When sending a Crown product to the factory for service, be sure to fill out the service information form found in the back of your manual and enclose it with your shipment, either inside the box or in a packing slip envelope securely attached to the outside of the shipping carton. Do not send the service information form separately. If you don't have your manual, you can also download a copy of the form here (pdf file, requires Adobe Acrobat to read).

Output power specifications are provided in the specifications area for each Crown amplifier model. If you can't find your model of Crown amplifier try the Legacy amps page.

This depends on the amplifier you have. Generally, you will first turn the power off, set the bridge mono switch to the bridge position and attach your speaker wires onto the two red binding posts of each channel. It is then necessary to apply your input signal to channel one on your amplifier and adjust the gain as needed. For some amplifiers, the gain of channel 2 must be turned all the way down while others are required to be all the way up.

The benefits of hooking up two subs to a mono amplifier are the same as hooking up any other number of subs to a mono amp: you can push the subs with more power at lower impedances. Because lower frequencies are less directional (i.e. it's more difficult for your ears to determine where low frequencies come from than highs), bass is often transmitted in mono. Mono here refers to a single channel (as opposed to stereo, or two channels), not one speaker.

A well-made stereo amplifier that is stable to 2 ohms should be able to handle up to four 4-ohm woofers (two subwoofers wired in parallel to each channel). If you want to bridge a 2-channel amp to one channel, it's best to only connect one 4-ohm woofer. The minimum impedance for the bridged (mono) output of a 2-channel amp is usually 4 ohms. Mono subwoofer amps, like the Kenwood KAC-819, are stable down to 2 ohms, allowing you to hook up two 4-ohm subs in parallel.

Yes. All dual channel Crown amplifiers can be treated as if they are two separate "mono" amplifiers (One channel completely independent of the other) For example: A Macro-Tech 1202 can function with a single eight-ohm speaker on channel one and four eight-ohm speakers (a two-ohm load) on channel two. A Com-Tech 410 can function with one or two eight-ohm speakers on one channel and the other channel switched to 70-volt operation.

Yes. The CP 64 has a Zone 1 Mono Switch located internally, directly in front of the Priority Assign switch.

Over twenty years of citizen advocacy underlie Mono Lake’s current protection. Before the Water Board decision protecting the lake could be achieved, important legal concepts were debated and decided upon. One of these debates related to restrictions that prohibit dam owners from drying up downstream fisheries. Written into the state’s Fish and Game codes, these provisions were not enforced until lawsuits were brought in the 1980s.

Any number of units can operate in parallel, be it in single phase, three phase or split phase configuration. However, battery capacity and DC cable cross section makes stacks of more than 6 units per phase unpractical. For more information, see 'Achieving the impossible' and our also Victron's publication â??Energy Unlimitedâ?? Run a Multi Plus in parallel with the Honda. A Multi 12/1600/70 will add sufficient power to the Honda.

The "Parallel" setting duplicates the effect of cross-patching the two inputs, using an internal switch to save the hassle of an extra cable. The two input jacks are connected together, so that a signal on either jack now appears in BOTH channels (therefore only a single signal should be connected). Each channel's Gain control regulates its volume as usual, and separate speakers are connected to each channel as usual.

Simply hardwire connect the Memory Recall Port (MRP) terminals numbered 5, 6 and 8 to the COM terminal. This will enable the unit to accept binary memory recall input and yield 24 memories.

Since we have come out with the Class D line of amplifiers, we have had an abundance of technical calls inquiring about how to bridge them. It isn't possible to bridge any mono-block Class D amplifiers. All of these models are Mono amplifiers, meaning they only have one channel. Then why does a single channel amp have two terminals (L and R)? We put both terminals there for your convenience. If you have two speakers, it is hard to attach two speaker leads under one terminal screw.

Our amplifiers with a Single volume control provide more convenience in operation over the Dual Mono control models. Originally all our amplifiers were Dual Mono volume control versions, due largely to our desire for excellence. The use of two volume controls (a 'Dual Mono system), is a method of minimizing both the number of contact points within the volume controls and the resultant distortion of the sound.

You do not want to have the gain on your amplifier set too high or there will be too much bass when you have it turned down. You also don't want to have the gain set too low or you may not be satisfied with the bass because there's not enough. Before you begin, turn the gain all the way down. Turn the volume on your deck up, close to full volume without the speakers distorting, and have the EQ settings at normal.

Auto-Negotiation passes the signals presently on the receiver to the 100BASE-TX and 100BASE-T4 Link Monitor functions. If Auto-Negotiation finds that exactly one Link Monitor function shows that the link is good, then it can connect that technology to the media. Note, however, that this function is only carried out for 10BASE-T, 100BASE-TX, and 100BASE-T4. Future multi-mode devices will use Auto-Negotiation as the basis of automatic mode switching.

In one sense, yes. Most X-10 compatible units described as being a "coupling amplifier" are, in reality, true "repeaters". Although somewhat confusing, ACT also manufactures true amplifiers (the CA000 and CA200) but they are almost never used in residential systems.

Two reasons: 1) All the music and sound effects are from the esteemed Valentino Library, and go back decades. They are, of course, in mono. And B) this is supposed to be an el-cheapo film from over 40 years ago; stereo back then was a four-track-magnetic affair, mostly reserved for three-hour-plus road shows with intermissions and all-star casts.

The Mono Project is an open development initiative sponsored by Novell to develop an open source, UNIX version of the Microsoft .NET development platform. Its objective is to enable UNIX developers to build and deploy cross-platform .NET Applications. The project implements various technologies developed by Microsoft that have now been submitted to the ECMA for standardization. The Mono Project has also sparked a lot of interest in developing C#-based components, libraries and frameworks.

First insure that the amplifier is switched off then set both cabs to Mono (Fig. 11.1) and connect a speaker cable to either of the TSL's Parallel loudspeaker outputs (Fig. 11.2). Connect the other end of the speaker cable to the first Cabinet's 16 Ohm input socket (Fig. 11.3). Plug a second speaker cable into the remaining parallel loudspeaker output on the head unit (Fig. 11.4) and insert the other end into the 16 Ohm input socket on the second cabinet (Fig. 11.5).
