INTRODUCTION
Thank you for your purchase!! The Nerve Audio PH-1.1 represents our
statement about the quality-versus-value cross point. We feel the PH-1.1.1 will
match performance against phono stages costing many times more.
The Nerve Audio PH-1.1 is a moving magnet phono preamplifier with RIAA
equalization that amplifies the output signal of a moving magnet phono cartridge
up to a nominal “line level” for use with any pre-amplifier, integrated amplifier, or
receiver. The PH-1.1 was designed by Jeff Boccaccio and features solid
construction, minimalist circuit topology, and low profile design. Designed for the
custom installer and budget conscious audio enthusiast, the slimline, brushed
aluminum case can be easily hidden behind a theater system for seamless
integration, but can also be handsome addition to any audio system. We
sincerely hope you enjoy the attention and detail that have been given to the
design and construction of the PH-1.1
Please thoroughly read these operating instructions for the PH-1.1 before
installing and connecting it to your audio system.
INSTALLATION
The PH-1.1ʼs small size and low-profile design mean it can be installed just about
anywhere, but there are a few things to consider when choosing where to place
your PH-1.1. The installation site should be not be exposed to high heat or
moisture, and adequate space should be provided for ventilation on all sides and
the top of the unit. Most importantly, the unit should be placed well away from
strong magnetic fields or other potential sources of noise, such as motors,
transformers, and video displays.

CONNECTIONS
CAUTION!! Before making any connections, please be certain that the outboard
power supply is NOT PLUGGED into an AC outlet.
PHONO INPUT: Connect the left and right RCA Phono cables from your
turntable to the corresponding inputs on the PH-1.1 (Figure 1).

Figure 1
OUTPUT: Connect an audio interconnect cable from the left and right outputs of
the PH-1.1 to the left and right high- level (ʻlineʼlevel) inputs on your preamplifier,
integrated amplifier, or receiver (Aux, Tuner, Tape, etc.) (Figure 2).

CAUTION!! Do not connect the output cables from the PH-1.1 (or any other high-
level device) to the phono inputs on a pre-amp, integrated amp, or receiver.

GROUND: If your turntable features a ground wire and requires grounding, attach
the ground lug or wire to the black binding post located on the output side of the
PH-1.1. Be careful not to over-tighten. (Figure 3).
Figure 3
POWER SUPPLY: The PH-1.1 uses a wall-adaptor style transformer power
supply. In order to minimize the risk of unwanted noise, the power supply’s
transformer should be located as far away from the PH-1.1 as possible.
Connect the power supply cord to the PH-1.1. Be sure the power supply
connector is fully seated (Figure 4). If the power supply connector is not fully
inserted (Figure 5), the PH- 1 will not power on.

Finally, connect the wall adaptor to an AC outlet. Your PH-1.1 is now ready to
use.

ØBe sure output of the PH-1.1 is connected to a high-level line
input on your pre-amp or receiver and not to a phono or mic level
input.
*** Please note: it is not usual to have to turn the volume up higher
when playing a record to get the same relative volume level as when
playing a CD or other high-level source. This is perfectly normal.
