QUICKSTEP BK
產品介紹

QUICKSTEP是一台在技術上異常講究的隨身耳擴。這款耳擴被設計的目的,是在隨身使用時達到最佳的音質,並盡量作到最小的體積與耗電量。
這款耳擴不僅運用了CORDA獨創主動式平衡接地的概念,同時也擁有精密的音量控制(32段,兩段增益可調)。這個音量控制並非一般工業用規格,而是使用了一組低耗能的ADC,再運用此ADC的輸出來調節音量,他所得到的是一個非常乾淨而富於細節的聲音,並且沒有任何的聲道不均衡狀況。 一般隨身耳擴的3.5插槽部分,常常是最脆弱的,但QUICKSTEP的3.5插槽卻非常耐用。另外,他也不會在輸入端對RF波起任何的反應,因此也可避免被手機所引發的RF波汙染音質
 

產品規格

Technical details
Measures: 8.8 x 6.6 x 2.2 cm
Weight without battery: 115 gr.
Supply voltage: 6 .. (9) .. 15 Volts DC
Mean current uptake: 35 mA / 20mA (high/low-current-consumption-mode)
Discrete volume control. Typical stepsize 1.5 dB, 31 steps.
Maximal amplification: 0 / 14 dB (low/high gain)
Active balanced headphone ground.
Star-grounding and ultra short signal paths.
Input impedance: 120 / 17 kOhm
Output impedance: < 1 Ohm
The unit runs from a single 9V battery and internally the supply voltage is used to create a pair of +4.5 and -4.5V powerlines (low current consumption mode) or a pair of +9 and -9V powerlines (high current consumption mode).
External powersupplies can be connected with voltages between 6V and 15V DC. This supply voltage is internally doubled to create a pair of +6..+15V and -6..-15V powerlines.
Noise is removed by extensive LC-filtering of the supply voltage.
RF-noise (iPhone!!) is removed by extensive filtering of the input signal.
The total buffer capacity is 4700 uF to lower the effective battery impedance.
For amplification five single OPA209 opamps are used for maximal sonic performance.(No dual or quad-opamps!)
The heavy-duty (!!) 3.5 mm sockets are gold-plated.
Inside the signal path only metal-resistors and high-quality film-capacitors are used (polypropylene).
The enclosure is made entirely of aluminium.
Accessories: 2 mini-mini interconnects (goldplated)
