• Corda Quickstep

The QUICKSTEP is simply one of the very best portable amplifiers on the market and uses the concept of balanced ground and a discrete volume control. In addition it has an extensive RF-filter of the input-signal which makes it immune to RF-pollution caused by mobile headphones

Features :

- Five single OPA209 opamps are used for maximal sonic performance (No dual or quad-opamps!).

- Alumunium body

- 3.5 mm gold-plated plugs

- Sophisticated Volume control

The amp not only uses the concept of active balanced ground but also has a discrete volume control (32 positions, two gain settings). This volume control is not a standard industrial solution but uses a concept in which the position of an analog potentiometer is measured using a low-power ADC and in which the output of this ADC is used to control electronic switches that set the volume level. The result is a very clean and detailed sound without any channel imbalances.

- Only metal-resistors and high-quality film-capacitors are used (polypropylene).

- Active balanced headphone ground.

- Star-grounding and ultra short signal paths.

Specifications :

- Measures: 8.8 x 6.6 x 2.2 cm

- Weight without battery: 115 gr.

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.

- 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: -3 / 14 dB (low/high gain)

- Input impedance: 120 / 17 kOhm

- Output impedance: < 1 Ohm

Accessories :

- 2 mini to mini interconnects

- Tool to open the amp

Available Colors :

- Silver
