De Quad 33 selecteert en bestuurt de radio-tuners, de grammofoon-opnemer en de bandrecorder die erop zijn aangesloten en voedt de luidsprekers via de vermogensversterker, zodat stereo, mono op een of beide kanalen, van alle ingangen, plus monitoring- en trackkeuzefuncties voor tape beschikbaar zijn .

Quad-units kunnen zowel vrijstaand als gemonteerd in een kast met veel ruimte voor individuele voorkeur in lay-out worden gebruikt.

Het standaard Quad-systeem van montage wordt gebruikt, waarbij alleen een rechthoekige uitsparing nodig is waarvoor een sjabloon is voorzien.

De bedieningselementen zijn uitgebreid maar eenvoudig en zijn logisch gegroepeerd om selectie en controle van het programma te vergemakkelijken.

Het filter is essentieel met moderne kwaliteitsluidsprekers en op elk moment nuttig.

Het verwijdert oppervlaktegeluid, het traceren van vervorming en vergelijkbare tekortkomingen in het bovenste frequentiebereik van de opname of uitzending, en het systeem met twee controlesystemen behaalt dit tot een zeer hoge graad zonder onnodig in het harmonische bereik binnen te dringen, dus essentieel voor een realistische weergave.

Specificaties: 33
Frequentiebereik: 30Hz tot 20kHz
Total harmonische vervorming: 0,02%
Ingangsgevoeligheid: 2mV (MM), 100mV (keramisch), 100mV (lijn)
Signaal / ruisverhouding: 70dB (MM), 85dB (lijn)
Uitgang: 100mV (lijn), 0.5V (Pre uit)
Afmetingen: 260 x 92 x 165 mm
Gewicht: 3kg

De Quad 303 is een tweekanaals eindversterker die voornamelijk is ontworpen voor hoogwaardige huishoudelijke installaties. De vier grote condensators zijn vervangen door vier 4700 ohm's. waardoor er meer e buffert kan worden.

Het is ideaal voor het besturen van luidsprekers in het bereik van 4 - 16 ohm en levert een output van maximaal 45 watt per kanaal, afhankelijk van de belastingsimpedantie.

De input vereist voor volledige uitvoer is 0,5 Vrms ongebalanceerd.

Transistor-triples worden gebruikt in een originele schakeling om een ​​volledig symmetrische eindtrap te verschaffen, ruststroom onafhankelijk van junctietemperatuur en symmetrische stroom- en spanningsbegrenzing.

Harmonische en intermodulatie distorsieproducten in het audiobereik zijn zo laag dat ze moeilijk in zinvolle termen kunnen worden gemeten.

De versterker is onvoorwaardelijk stabiel en kan met elke belasting worden gebruikt.

Voor speciale toepassingen waarbij continu vermogen nodig is voor lage (minder dan 8 ohm) of reactieve belastingen, zoals het aandrijven van synchrone motoren, enz., Kan het maximale vermogen of de maximale duty cycle worden beperkt door het vermogen van de warmteafleider om de gegenereerde warmte af te voeren (max. temperatuur 70 graden).

De twee kanalen kunnen samen of onafhankelijk worden gebruikt, maar de twee uitgangen zouden niet parallel moeten zijn zonder een of andere vorm van stroomverdelingsnetwerk op te nemen.

Specificaties: 303
Uitgangsvermogen: 45 watt per kanaal in 8Ω (stereo)
Frequentiebereik: 30Hz tot 35kHz
Totale harmonische vervorming: 0,1%
Ingangsgevoeligheid: 0.5V
Signaal / ruisverhouding: 100dB
Laadkracht impedantie: 4Ω tot 16Ω
Afmetingen: 120 x 159 x 324 mm
Gewicht: 8,2 kg

Unique Objects

Occasionally, two different bidders may show up in the bidding history with the same bid amount. This occurs when one user's bid is exactly the same as an automatic (maximum) bid placed by another user earlier. Since the auto-bid was placed first, this takes preference. The bidding history will show both bids, with the auto-bid ranked as the higher of the two.


Double bid

It may appear that the same bid has been placed by two different bidders. This can occur if someone places a bid in another currency which is then rounded to the same amount as the previous bid in %{local_currency}.

This can occur for the following reasons:
1. If an opening bid does not meet a lot’s reserve price (hidden minimum), buyers may try outbidding their earlier bid in order to find that lot’s RP.
2. If an auto-bid (user-set maximum bid) is outbid, the bidding log will show the first and final steps of that user's auto-bid in a row. The new highest bid will be shown at the top.

Why is this bidder outbidding him- or herself?

Bids exclude the auction fee and shipping costs, which will be added during final payment.
