4 INSTALLATION
1 INTRODUCTION
The Sound Enhancer can be used in many different roles and there
are
many ways to connect
the unit. This chapter lists some,
(NOT
ALL) of
the
m o s t
frequently used applications and related installations. Some experi ‑
mentation m a y be necessary.
The Digital Signal Processor in the Sound Enhancer is controlled via the
SELECT
switches. However, three principal functions can be performed
without using the
SELECT
switches. These are:
ms A/D conversion;
m
D/A
conversion;
= Sample rate conversion.
The function is defined by the connected input(s) and output(s). The pos ‑
sible input/output combinations are:
= analog/analog the Sound Enhancer
acts
as an
A/D and D/A
converter.
= analog/digital the Sound Enhancer acts as an A/D converter;
= digital/analog the Sound Enhancer acts as a D/A
converter;
a digital/digital the Sound Enhancer will act as aSample Rate Converter.
In these four modes of operation three different capabilities
are
provided
by the Sound Enhancer:
- Sample
rate
conversion
- Synchronization
- Pitch control (varispeed)
These functions are implicit and
cannot
be disabled by the
user;
refer to
figure 6.1.
Notes:
1. Make
s u r e
the wiring/pin assignment is in accordance with figure 3.2.
Cables
should only be connected
to,
or disconnected from, the Sound
Enhancer when it is switched
OFF.
2. Refer to Note on page 4 for installation of the mains adapter.
3. The mains adapter contains a transformer. In the event that unwanted
influence on the audio performance of other equipment is observed it
m a y
be necessary to relocate the mains adapter.
4.
The Sound Enhancer has no phono amplifier on board, so the phono
o u t p u t of a record player should n o t be connected directly to the
ANALOG
IN socket. Instead it
m u s t
be connected to the
PHONO
IN con
‑
n e c t o r of an amplifier
for RIAA correction.
