Question about Crown CE1000 2-Channel Amplifier

Open Question

Hi there, I need some help deciding if this power amp is right for my speakers. I have a pair of Yamaha S115 Noise: 250 W PGM: 500 W Peak:1000 W Impedance 8 ohms And I was planning on buying a used Crown CE1000 on guitar center. This amp runs 1,100 @ 4 ohms bridge mono (http://www.iceco.com/Crown/CE1000.pdf), so I wanted to bridge both speakers in parallel so I could connect them to the amp and run them @ 550 W per speaker. Is this technically correct or possible? Can I achieve this by simply connecting one speaker to another and then one to the power amp in bridge mode? Thanks in advance to your responses!

SOURCE: CROWN CE1000- slips into fault immediately after connection

if ur output power amp is defective u will have that problem - meaning the moment u connect load across it it will go into circuit protection to limit/stop excessive output current. make sure the speaker terminals are connected to +/- output terminals. in bridge mode use only channel 1 and that too with 4 ohms speaker only otherwise amp will clip. considering all connections are okay if it still clips when speaker is connected, u have a faulty power amp section. this the way ur amp is designed

Hi,I have two 250w speakers at 8ohms ,could someone tell me if I need to get a amp with higher watts than the speakers?k


Speakers are rated either at RMS (root mean square) average power or Peak Power. An RMS of about 125 watt is equivalent to 250 watt peak. To match the radio and speakers they both need to be consistent. Also do not be confused with total radio power out vs per channel.

So if the speakers are 250 watt peak power then a radio with 125 watt per channel or 250 watt peak per channel would be a good match.
If the speakers are RMS 250 watt then the radio would be 250 RMS/channel and usually with a four channel radio a total of 1000W RMS
With that much power the neighbors should hear you coming!

Will the amp blow my speakers?


If you bridge the amp and get 1000 watts RMS and that is split going to two speakers then you will get 500 watts RMS at each speaker. If you have your amplifier on maximum gain it may blow your speakers, not because they are overpowered but because you might run into "clipping" issues running the amp at maximum capacity. Just to be safe I would dial the amp's gain down to 3/4 of the way to full gain. That should give you ample power and keep your amp from clipping and running hot.

Will a Pyle PT530A 350watt receiver work with a pair of 4ohm 200wattRMS per speaker


Yes they will, but alway be careful with audio gear.
There are 30 watt speakers that can handle peaks of 500 watts for a short time. There are also 500 watt speakers I can "kill" with a peak less than 500 watt.
Most amplifier manufactures like to boost about the power an amplifier can deliver and their speakers can handle. But as long as they don't tell how long the speaker can handle the power and at what frequencies the value does not say anything.
Whit high power amplifiers, never switch over while the volume if at maximum.
You know what I mean. I can't hear my CD player. first turn the volume to the max and then press the CD button, and the speakers will explode. Always when you preaa any button on the pre amp juts lower de volume first and you won't destroy your speakers.
My old Kef Concerto's are almost 40 years of age. 30 watt and are running on a 500 watt Yamaha amplifier for years now. And believe me my chidden know how to punish a speaker. Never any problem, nr with the speakers, nor with the amplifiers.

Is it possible to connect two jacks simulteanously to a speaker like S115 or SW118 coming from 2 different channels of a power amplifier like P5000S' please advise thanks


the s115 and p5000s are power matched for a single channel.
IE - the s115 is rated at 500W and the p5000s is 500W PER CHANNEL.
If you're trying to drive a left/right signal into a single speaker, you need to mix the left right signals together at the input side, and put the mix into a single channel of the amp, and then into the speaker from that one channel.

The other option is to have 2 s115's - one on each channel.

What is the best powered mixer to go with my b215xl 1000watt speakers


The PMP 6000 or 4000 depending on how many channels and effects you need is a good match.

READ THE SPECS... the speakers are capable of 250 Watts RMS (not 1000 as that is PEAK) power... like the ridiculous claims of 4 Hp for shop vacuums that run on 120 volts.

The 4000 and 6000 will generate about 250 Watts per side into 8 ohm speakers so is well matched for the B215XL speakers... by matched we mean the speakers are not likely to get blown out.

Connect a 500 Watt per side amp to the speakers and you will be buying replacements in short order.

ALSO realize how much sound you will get from the speakers.. they will cover a 2000 square foot venue fairly well. I suggest you get a sound level meter so you have a metric of levels when you are using the system. If you need more sound, you can add a second set of the speakers in parallel.

Would a Pyramid 15" subwoofer work for my Yamaha synthasiser?


Do yourself a favor do not get anything Pyramid they are cheap for a reason and you will not get good bass response from them even in a optimal enclosure.If you want nice bass for little money go with lanzar opti 1535D sub you can pick one up for around $265 and will blow away Pyramid any day.

    Ok...im getting a speaker that has an 8 nominal load and 600W peak 400Wprogram and 200W RMS...two...what is RMS and what kind of amp do i need so that i dont get screwd over. thank you bunchesand also i...


    RMs is the average power (really basically) > You need to get an amp that is around 150W - 180 WRMS. You need to be really specific about the rms. Dont let guys tell you 1000 W peak etc. Peak is term that can often have several meanings, but true RMS is the norm standard for assesing proper power in pro gear. Whatever you find check out the specs for yourself in writing!!!
    Hope it helps
