Maximum input level should not 21 dBu.
This value is reduced to +15/+9 dBu if
PRE-GAIN
is set to +6/+12 dB !!
RCA socket as outputs:
The RCA sockets can also be operated as
outputs
. This offers the
possibility of using a refreshed balanced or USB input signal for further
purposes.
Output levels equal the levels applied to the inputs, i.e. the signal is
amplified by 0dB (unity gain) at an output impedance of < 1 ohms.

THE OPTIONAL DIGITAL INPUT
Currently the HPA V280 can be fitted with one out of seven D/A converter
types, with three different inputs and a max. sample rate of 96 or 192 kHz:
The
COAX
input accepts digital PCM audio data in S/P-DIF format, at
sample rates from 28 to 108 kHz (or 210 kHz resp.).
The
OPTO
input, fitted with a TOS-LINK interface, accepts digital audio
data at sample rates from 28 to 108 kHz (or 210 kHz resp.).
The
USB
type
“B“ input can be connected to a host computer (PC or
laptop). The USB module will automatically be detected as an audio
device.
The
USB 96
input is compatible with USB 1.1 and 2.0 standards. It
accepts digital audio formats up to 24 bit at sample rates of 44.1, 48 and
96 kHz, while 88.2 kHz is not supported.
The
96 kHz
digital modules comprise a D/A converter with a dynamic
range of 110 dB and
–100dB THD+N, thus ranging in the upper-mid
performance class.
There are
TWO
different
USB 192
modules, compatible with the USB
2.0 standard. Both require a proprietary driver, which can be
downloaded from
www.violectric.de
Digital audio formats up to 24 bit at sample rates of 44.1, 48, 88.2, 96,
176.4 and 192 kHz are supported, as well as the so-called
“asynchronous mode”.
