Τους ειδαμε στο show του ΤOKIO/TOKYO σε στατικη επιδειξη.
Η Mark Levinson ανακοινωσε και επισημα τους δυο νεους ενισχυτες.
300w στα 8Ω, ο 531Η mono και ο 532H dual-mono.
S / N Ratio: 85dB or more (1W standards)
input: XLR × 1, RCA × 1
Dimensions: 451W × 194H × 504Dmm Weight: 23.8kg
(532H).....input: XLR × 1/ch, RCA × 1/ch/Weight: 33.6 kg
From input to output, amplifier circuit configuration adopted a fully balanced symmetrical layout. This common-mode noise, which will reduce both the differential mode noise. No.531H1、「No.532H」2The monolithic amplifier module includes channel independent power transformer, "No.531H" to one group, "No.532H" to be equipped with two units.
Borutejigeinsuteji up from the input signal path to minimize the circuit configuration uses a simple and compact. No high-speed signal propagation and transmission loss was less rapid signal processing allows the phase rotation and parasitic capacitance.
In order to supply power directly to the audio circuit balanced configuration, with a rectifier power supply circuit capacity on the same board. The power circuitry on the main board directly to a large toroidal power transformer for each channel independently, which reduces power loss and eliminates the increase in impedance of the circuit to supply power to the power stage in the shortest distance.
In addition, the rectifier and capacitors ensure sufficient capacity for the large number of capacitors connected in parallel and agile small capacity, low loss of the strict power / power supply design speed adopted. Leveraging this simple audio circuit, that allow you to further speed gain.
In addition, across the output circuit using a large heat sink, a physical separation between the parts of the circuit and power supply input Borutejigeinsuteji. Is to minimize interference.
10Hz20kHzS/N (1W 85dB Frequency response is 10Hz to 20kHz in, S / N Ratio (1W standards) is more than 85dB. 「No.531H」RCAXLR1「No.532H」RCAXLR1/chInput is "No.531H" to RCA (unbalanced) and XLR (balanced) each time one strains, "No.532H" RCA (unbalanced) and XLR (balanced) each one strain / ch are equipped .60kΩ30kΩ。 Balanced input impedance is 60kΩ, unbalanced 30kΩ.
