Topping A30 PRO

Topping A30Pro - incredible performance-

- NFCA Headphone Amplifier

- Bypass Output

- Signal pass through even when power is off

- Supports Hi-Res Audio

- Analogue outputs (front): 4-pin XLR, 4.4mm Pentaconn, 6.35mm jack socket

- Analogue inputs (rear): 2 x 3-pin XLR (balanced), stereo RCA (L+R)

- Pass Through outputs (rear): 1 x 6.35mm TRS (L+R), 1 x stereo RCA (L+R)

- Three gain levels: +14dB / 0dB / -14dB - <0.00006% THD+N

- <0.3uVRMS noise floor

-Maximum output power 2 x 6000mW at 16 ohms / 2 x 840mW at 300 ohms

 

The Topping A30Pro's features place it in the upper mid-range of headphone amplifiers.

- Housing machined from solid aluminium

- Maximum performance in this price range

- NFCA modules and noise values below 0.00006%. This means an incredible 99.99994% of the original audio information is reproduced at the analogue outputs.

- 10 operational amplifiers OPA1656, 5 per channel

 

Output power

2 x 6 watts at 16 ohms

2 x 5.5 watts at 32 ohms

2 x 840 mW at 300 ohms

2 x 420 mW at 600 Ohm

With this enormous output power, even high-impedance studio headphones can be driven properly.

 

Routing of the input signal

Both the RCA and the XLR input signal can be looped through, even when the unit is switched off.

RCA input to RCA output

XLR input to TRS output

This scenario makes sense if the signal is to be routed directly to an external amplifier or active loudspeaker without using the headphone amplifier.

 

Ground Loop Noise

The connection of many different units to each other can lead to ground hum.

To eliminate this problem, the Topping A30Pro has a "Ground/Lift" switch on the rear panel. In normal operation, the switch should be set to the (GND) position. Possible ground hum can be passed on to the device connected to the Topping A30Pro via the (Lift) position by shifting the device ground and thus eliminating it.

 

The Best Partnership

To enjoy the full potential of the Topping A30Pro, we recommend the Topping D30Pro digital analogue converter with its 4 x CS43198 Quad DAC setting and extremely low jitter.
