Emerald

£11,390

Van den Hul have used the same design ideas from the Grail SB, like the complete balanced DC coupled circuitry, HF PCB with 24 carat gold connections and 0.1% precise selected components. The very innovative electronic circuitry is able to handle a mix of balanced and unbalanced signals both on the input and output.

To adjust all essential replay values, a remote control is part of the design. The channel to be used, the replay levels and possible channel unbalance can be fine-tuned. To avoid any spurious signals and magnetic induction, the amplifier housing is made of 6 & 10 mm thick steel.

Specifically, the very natural and specific spacious replay is a benchmark of The Emerald. The very high resolution in combination with the natural dynamics in replay is another remarkable property.

Input connectors and input resistance:

– Remote controlled inputs: 2 balanced stereo inputs + 2 unbalanced stereo inputs
– Input resistance: 10KOhms resp. to ground

Output connectors and output resistance

– output: 1 balanced stereo output + 1 unbalanced stereo output. both outputs (bal. + unbal.) are simultaneously available if input resistance of the following power amplifiers are above 10KOhms in parallel circuit.
– output impedance (on all outputs): appr. 350 Ohms
– output voltage: >= 6Vss on balanced output.

Bandwidth and distortion

– appr. 5Hz … 20KHz +- 0.2dB
– distortion: less 0,01% (1KHz) at 1Vrms at balanced output.

Level adjustment

remote controlled 128-step level attenuator with special low-level signal relais (switched resistor array with constant input resistance) with 0,75dB/step

max. attenuation: -95,25dB. The step level attenuator circuit also makes possible a channel balance adjustment and a signal muting function, also operated by the infrared remote control.
