WVR7200 Specifications and Performance Verification
Performance requirement
+24 dBu ±0.5 dBu
± 0.5 dB, 20 Hz to 20 kHz, 0 to –40 dBFS,
20 or 24 bit input
± 0.8 dB, 20 Hz to 20 kHz, 24 dBu to –16 dBu
Reference information
Balanced: provides a full-scale output of
24 dBu and is designed for professional
balanced applications
Unbalanced: Designed to drive the
unbalanced inputs of consumer amplifiers, in
which case the negative output pin must be
grounded
The channels routed to the line outputs may
include: Embedded audio source, AES audio
source, Analog audio source, and Decoded
Dolby
Provides up to eight channels
Balanced, unterminated via rear panel
connector
62 pin, 3 row, DSUB connector, but only 2
rows of 42 pins are connected
Ground negative output to support
unbalanced mode
When one output is grounded to achieve
unbalanced mode, the other output will be
driven to a larger amplitude. You can reduce
the level by adding attenuation in the Audio
Settings menu. Do not exceed the maximum
rated output power in either mode
0 dB to –120 dB in 0.5 dB steps
50 Ω
Intended to drive ≥600 Ω load. Drivers
are capable of driving a minimum load
impedance of 300 Ω but may overheat. DO
NOT exceed maximum rated output power
≤0.01% from full scale to –20 dBFS, 20 Hz to
20 kHz
≤0.02% from full scale to –20 dBFS, 20 Hz to
20 kHz
<–90 dB, 20 Hz to 20 kHz, 24 dBu or 0 dBFS
input
<–100 dB, 20 Hz to 2 kHz, 24 dBu or 0 dBFS
