UAD Powered Plug-Ins Manual - 555 - Chapter 55: Studer A800
Hum Noise
The Hum Noise frequency is dependent on the setting of the Equaliser (Em-
phasis EQ) control ( page 550 ). The frequency is 60 Hz when set to NAB (US)
and 50 Hz when set to CCIR (European).
Note: When IPS (Tape Speed) is set to 30 IPS, the yellow Equaliser (Empha-
sis EQ) LEDs are not illuminated, indicating that the Emphasis EQ is set to
AES. However, in 30 IPS mode, the Equaliser switch can still be changed to
set the frequency of Hum Noise.
Hiss Noise
Just like the hardware, the amount of hiss is dependent on settings of the var-
ious controls. Overall Hiss Noise is set with this control, but may change
based on the Path Select, Tape Speed, Tape Type, Emphasis EQ, Cal Level,
Bias, Playback EQs, and Output Level controls.
Because hiss noise is an element of t ape playback, Hiss is disabled when
Path Select is to INPUT.
Note: Hiss timbre and level can change with Tape Type.
Studer A800 Latency
The Studer A800 uses an internal upsampling technique. This upsampling re-
sults in a slightly larger latency than most other UAD plug-ins. See
“Compen-
sating Upsampled Plug-Ins” on page 108 for more information.
