How does the reliability of the Digital 328 com-

pare to an analogue console? Traditionally, ana-

logue consoles have been constructed using a sin-

gle printed circuit board for each channel, plus

one board for each function in the master section.

Each circuit board uses conventional electronic

components, and the boards are linked together

by ribbon cables. The Spirit Digital 328, on the

other hand, uses 'surface mount' technology and

high density printed circuit boards. Surface-

mount technology has been widely used in the

computer industry, improving reliability and

speed.

IS THE OPERATING SYSTEM 

UPGRADEABLE?

Yes: newer versions of the 328 Operating System

will be made available through the Digital 328 web

site (www.digital328.com), or as an upgrade kit

from Spirit distributors. These updates will be

accessible as soon as new versions are released,

and (internet updates only) available at any time

of the day. All software upgrades are provided free

of charge by Spirit.

* Wordclock output on BNC (TTL level)

* 1 SMPTE input on quarter-inch jack

* Sony 9 pin for Machine Control ( RS-422 )

* Cascade Port on 26 way HD D-type connector

HOW MANY EXTERNAL DIGITAL

RECORDERS CAN BE USED AT ONCE?

Two. The Spirit Digital 328 has two Alesis Optical

and two Tascam TDIF interfaces located on the

back panel, one of each for each set of eight tape

inputs (17-24, 25-32). The front panel includes

transport controls, with locator points, and the

ability to arm (and indicate arming) any of the 16

tracks for recording.  If two 328s are linked via

the cascade facility, up to four recorders (with 32

tape channels) can be used.

ARE THERE ANY DIGITAL AUX SENDS?

Yes.  A third Alesis ADAT format Optical output

(labelled Aux) is located on the back panel. The

source for the eight channels of this Aux Optical

Output can be set to come from the AUX bus, FX

bus, MIX output or Group buses. Companies such

as Alesis and TC Electronics are already designing

effects units with Optical In/Out, as well as stan-
dard quarter-inch jacks.

CAN A CD OR DAT MACHINE BE CON-

NECTED DIGITALLY?

Yes. Most professional, and some consumer, audio

DAT and CD-R machines include stereo digital

input ports. Simply assign the MIX Outputs to the

digital AES/EBU or SPDIF outputs, and send that

signal in the digital domain to the Input of the

DAT or CD-R recorder.

WHAT TYPE OF MIC PREAMPS DOES

THE DIGITAL 328 HAVE?

The Digital 328 incorporates Spirit's own UK-

designed-and-built UltraMic Plus

+

mic preamps

on channels 1-16. This acclaimed preamp design

has the ability to handle a wide range of signals,

with a massive 66dB of gain range and +28dBu

maximum input level.  This caters for virtually all

high level outputs that are likely to be passed

through the preamp.

HOW DO GROUP ASSIGNMENTS

WORK?

Simply select the channel you wish to assign, then

choose the group(s) to which you wish to assign
