INTRODUCTION

The HPAMP104 is a 4-channel Headphone Amplier boxed in a very compact and portable package, allowing

up to 4 dierent people to listen to the same program, while each listener can set its own volume level using

the dedicated output level controls.

HPAMP104 features one input in ¼” JACK and a standard dual RCA jacks that can be set as stereo or mono. The

signal is amplied and sent to 4 x ¼” JACK stereo headphone outputs with individual level controls, each one

with +20dB max output level (per channel). Each output is capable of driving 16 ohm output load impedance.

HPAMP104 is powered by a DC adaptor included with the unit.

CONTROLS AND AUDIO CONNECTION

1. HEADPHONES stereo jack outputs

These are the 4 STEREO JACK connectors for the headphones output: only stereo headphones with a minimum

impedance of 16 Ohms should be connected to these outputs. The stereo jack connectors are wired as

follow:

Tip = posive LEFT channel signal

Ring = posive RIGHT channel signal

Sleeve = common negave shield or ground for both channels

2. HEADPHONES LEVEL controls

These controls set individually the level of each HEADPHONES output. The signal of the 4 outputs is the

same.

3. PWR indicator

The PWR LED shows when the HPAMP104 is powered. If the LED doesn’t light, be sure that the DC ADAPTOR

is connected to the mains line and to the HPAMP104.

4. 12-18VDC socket

Here’s where you plug in your external power supply. You should always connect your power supply to the

HPAMP104 before you plug the power supply into an electrical outlet. Make sure that all level output knobs

are turned all the way down when powering your HPAMP104.

5. STEREO / MONO switch

This switch set the inputs as stereo or mono, when set as MONO only the signal of the LEFT input (RCA or JACK

p) is send to both le and right earphone of each headphone output.

6. RCA Input

These are two female RCA connectors, which accept a line level input signal from almost any source. White

idenes the LEFT channel and red the RIGHT channel. They are wired as follow:

Tip = + posive signal

Sleeve = shield or ground

7. STEREO JACK Input

This is a STEREO JACK connector, which accept a line level input signal from almost any source, also an

HEADPHONES output of another device. This is used alternavely to RCA inputs and it is wired as follow:

Tip = posive LEFT channel signal

Ring = posive RIGHT channel signal

Sleeve = common negave shield or ground for both channels

When it used as mono input only the Tip signal is send to both le and right earphone of each headphone

output.
