WELCOME

Welcome to Statement, and many congratulations on your investment in music. The Statement
NAC S1 preamplifier and Statement NAP S1 mono power amplifiers are an expression of all we
know about audio amplification. Every lesson learned and technology developed over four decades
of Nim amplification has its place in the NAC S1 and NAP S1. They are also however about new
ideas and technologies and without doubt constitute the most technologically advanced analogue
audio amplification the world has ever seen, or heard.

As befits their fundamentally simple purpose, the Statement amplifiers are relatively simple
products to install and to use. They do however require some thought and care on setup, and
getting the absolute best from them will be far more likely if you are familiar with the contents
of this manual.

The manual covers both the NAC S1 preamplifier and NAP S1 power amplifiers. It describes
their use both when connected together using the CAN bus system and when used independently.
CAN bus integrates preamplifier and power amplifier control so that they behave as an
integrated unit.

Your Statement amplifiers will have been initially installed by your Nim retailer who will have
unpacked, positioned, levelled and connected the units appropriately. While this manual covers
positioning, levelling, mains power, input and output connection, setup, operation and care,
it does not include information or guidance on unpacking, packing or shipping. Should you require
in the future to repack or ship your Statement amplifiers without the assistance of a Nim retailer
the necessary information can be found in the Statement Installation Manual. The Installation
Manual is shipped with Statement amplifiers but can also can be found at:
www.nimaudio.com/support.

The manual begins in Section 1 with information on NAC S1 and NAP S1 positioning, levelling and
mains power connection. NAC S1 connections are described in Section 2 and NAP S1 connections
Section 3. The manual continues with setup, operation and care in subsequent sections. Please also
read the Safety Warnings contained within the Installation Manual.

The NAC S1 preamplifier (or CAN bus integrated preamplifier and power amplifier) can be
controlled through either its top panel buttons and volume control or via the supplied Statement
remote handset. Please do not switch-on your Statement preamplifier or power amplifiers until
all connections have been made and until you have read this manual.

Statement amplifiers are supplied with an accessory pack containing this manual and the
following items:

• The Statement Story
* The NAC S1 /NAP S1 Installation Manual

• The Statement Remote Control Handset and 4 x AAA batteries (NAC S1 only)

• Floor protectors
(quantity appropriate for preamplifier only or preamplifier and power amplifiers)

• Floor spike adjustment tommy-bar

• Spirit-level

• Remote Control Handset battery cover allen key

• Speaker terminal wrench

1.0 INSTALL ATION

The following Section 1 paragraphs refer to both the NAC S1 preamplifier and NAP S1
power amplifiers.

1.1 POSITIONING

WARNING. Statement amplifiers are extremely heavy and to minimise the risk of damage or
personal injury they should be lifted and moved by at least three people working together.

Your Statement preamplifier and power amplifiers can generally be positioned in your listening
room as convenience dictates. There are however some constraints to consider:

• For best performance Statement amplifiers should ideally be connected directly
to wall-mounted mains outlet sockets using only the supplied PowerLine mains cables.
Each Statement unit must therefore be located within 1m of a mains outlet socket.

• If a NAC S1 preamplifier is to be used with a Nim 500 Series or Classic Series power amplifier
(most likely a NAP 500 or NAP 300), the distance between the NAC S1 and the power amplifier
will be constrained by the 1m interconnect cable length.

• If a NAC S1 preamplifier is to be used with NAP S1 power amplifiers, the distance between
the preamplifier and power amplifiers is less constrained by interconnect cable length.
The supplied interconnect cables are 560mm long, however cables of up to 10m length may
be used. Your Nim retailer will be able to supply cables made-up to the required length.

NOTE. One of each pair of NAP S1 power amplifiers is nominated as the “left” power amplifier and
one nominated as the “right” power amplifier. Left (L) and right (R) identification can be found on NAP S1
connection panels. Ensure when positioning a pair of NAP S1 power amplifiers that each one is sited
appropriately for connection to its left and right inputs and outputs.

IMPORTANT NOTE. The NAC S1 has setup buttons and indicators located on its connection
panel. Ensure the connection panel is accessible following installation to enable configuration.

1.2 LEVELLING

Statement amplifiers are fitted with floor-spikes to define their mechanical interface with the
structure of the listening room and to ensure that their internal isolation systems work optimally.
The floor-spikes should be adjusted so that the amplifiers are perfectly vertical and do not rock.
The Statement spirit level included in the accessory pack is designed to aid levelling adjustment.

N O T E . Statement amplifiers are fitted with floor spike covers when shipped. Remove the covers
simply by pulling them off.

To adjust a floor-spike, first loosen its lock-nut using the supplied tommy-bar. Next turn the floor­spike as appropriate using the tommy-bar inserted in the floor-spike through-hole. Re-tighten the
lock-nut when adjustment is complete. Use the minimum length of floor-spike needed to hold the
lock nut just above the carpet.

N O T E . If your Statement amplifiers are to be installed on a non-carpeted floor, the floor spikes should
be used in conjunction with the Nim floor protectors included in the accessory pack and adjusted so
that the tapered part of the floor-spike extends just beyond the lock nut.

1.3 MAINS CONNECTION

Statement amplifiers are supplied with a Nim PowerLine mains cables. The PowerLine is
fundamental to Statement audio performance. Alternative mains cables should not be used.

NOTE. Before connecting your Statement amplifiers to the mains supply check that the mains voltage
specified on the connection panels is appropriate for your territory.

The NAC S1 and NAP S1 should ideally be connected directly to wall mounted mains outlets. If it is
necessary to use a multi-gang mains distribution block it should be of a type specifically designed
for high performance audio applications. Your local Nim retailer will be able to advise on mains
distribution blocks. If the wall mounted mains socket or distribution block incorporates isolation
switches they should remain switched-off until your Statement amplifier installation is complete.
