Naim IXO Crossover, good fully working condition, original box, Snaic Cable and Manual Here we have a relatively rare piece of electronic equipment from British company Naim Audio. It is the IXO Crossover and our unit dates from 1998 and comes in good condition, just one slight mark on the fascia – please see photographs. It is supplied in original factory packaging, with manual, and SNAIC cable. Naim Say…. The launch of our new active crossover, the IXO, has prompted a number of questions from people unfamiliar with the way in which active systems work, so we thought a few words about their benefits would be useful and interesting. The loudspeakers in most hi-fi systems have either two or three separate drive units to cover the full range of frequencies from bass through the mid-range to treble. In a passive set-up the signal coming from the power amplifier contains all of this information, so a circuit is needed to separate out the different frequency bands and distribute them to the appropriate drivers. The simplest and cheapest way to do this is with a passive filter network – the crossover. This is a circuit board fitted with electronic components, mounted either inside or outside the loudspeaker cabinet. The main disadvantages of this method are that dividing up high levels of current in this way introduces distortion, the enemy of all high quality audio systems, wastes amplifier power, and thus reduces control over the loudspeaker. An active system is quite different. The crossover now contains “active” devices such as transistors and op-amps (therefore it requires a power supply) and is connected between the preamp and the power amplifier, with separate power amplifiers for each frequency band. The IXO crossover has a built in power supply and is designed for use primarily with the Intro and Credo loudspeakers. The IXO features various technologies to reduce microphonic effects, in particular a compliant mounting for the main circuit boards and the DIN sockets on the rear. On the rear of the IXO Active Crossover there are controls to adjust the High Frequency and Low Frequency outputs. These are normally preset when the unit leaves our factory but may be fine-tuned to suit the listener’s preferences. Active filters have lower distortion than passive ones, due to the elimination of cored inductors and the use of higher quality lower value capacitors. Inter-modulation distortion in the power amplifiers is reduced due to operation over a narrower bandwidth (i.e., just treble). Effectively the power amplifiers are connected directly to each driver, thus driving them from a lower impedance source, which tends to suppress the fundamental resonance via electromagnetic damping and reduces distortion. Variations in driver sensitivity or room characteristics can be easily controlled via gain control potentiometers. If all this sounds a bit technical, don’t worry. Our active systems are relatively easy to set-up and use and the real benefit, better sound quality is evident from the moment you play music on them.

If you are outside the UK you will need a shipping quote BEFORE buying. Delivery time:48 hours Payment We accept the following payment methods: Paypal Credit/Debit Card BACS Please contact us if you have any questions. Service Established in 2003, 2ndhandhifi is the UKs largest stockist of used quality audio equipment. All items are checked before despatch and guaranteed for 30 days for ebay buyers to give you peace of mind that the item will arrive safely and work exactly as per ebay descriiptions. This means that all items described as used will be in good working order but may show minimal cosmetic marks resulting from everyday use. Any more significant cosmetic issues will be highlighted in the listing if present. We accept most payment methods but card payment to our shop is preferred. We use a reputable overnight courier service - items will be despatched next working day for delivery the next working day after that, but you are welcome to collect from our sister shop in Stockton on Tees if you prefer. Check our feedback if you have any doubts about the validity of this auction or us! We are a business so (although most times we do) we cannot always answer emails over the weekend so please try to ask Monday to Friday. Important 1. If there is no buy it now price stated, please dont ask - it is intended to be an auction which will run until its end time. 2. If you are outside the UK mainland please ask us for a shipping quote BEFORE placing a bid or clicking “Buy it Now”. If you dont ask, it means you will accept our quote. We do not cut corners on shipping, we only use reliable shipping companies, and we dont profit from the shipping prices we quote. 3. For any item where there is no original packaging the shipping costs include the cost to package the item to ensure safe delivery. Larger items may be shipped on a pallet - but this usually will be stated in the listing. 4. If you win the auction or buy the item, we expect you to pay and we will issue a non payment against you if you dont. Such auctions/listings cost us time (and therefore money). Requests to cancel will be rejected.
