then to a grounded, three-prong AC wall outlet. See the audio card documentation delivered
with the system for more detailed connection information.
If the system includes a multimedia keyboard, see the multimedia keyboard documentation
delivered with the system for connection information.
After you start the system for the first time, you may want to change the microphone’s BIAS
setting to ensure the microphone works properly with the system. You can locate the Mic
BIAS setting on the Microphone panel of the Ensoniq Mixer in Windows NT 4.0 and on the
Settings tab of the Windows 95 driver. If desired, apply a 30-dB gain to the microphone
input by checking the Boost box in the Microphone panel of the Ensoniq Mixer.
NOTE Disable the BIAS power if you use a dynamic microphone. Distortion may occur if BIAS
power is enabled with some dynamic microphones.
Connecting an External SCSI Device
If your system includes an optional SCSI adapter card, you can connect internal and external
SCSI devices, such as hard disk drives or tape drives, to the system. Internal SCSI devices
included in the system are already connected to the internal channel of the SCSI adapter.
You can connect external devices to the external port on the SCSI adapter.
The SCSI adapter card is designed to support Ultra Wide SCSI devices. Ultra Wide SCSI
provides a maximum data transfer rate of 40 MB per second. If you connect a non-Ultra
Wide SCSI device to the adapter, data transfer rates are limited to the speed of that device.
CAUTION Using a non-compliant SCSI-1 device with your system may cause your system to stop
working or lead to other unpredictable results.
You can connect up to seven external single-ended SCSI devices to an installed SCSI
adapter. However, the number of drives and length of the cables used to connect the drives
is a factor when using SCSI-1, Fast SCSI (SCSI-2), Ultra SCSI, and Wide Ultra SCSI drives.
Fast SCSI, Ultra SCSI, and Wide Ultra SCSI impose shorter cable restrictions than SCSI-1.
The total length of the SCSI cabling must not exceed the following:
Drives SCSI-1 Fast SCSI-2 Ultra SCSI Wide Ultra SCSI

NOTE You must count the SCSI adapter as one device.
