ENGLISH

•Do not connect speakers and turn on power until you have read this

manual thoroughly.

•While unpacking the DMS80 inspect all items for quality of appear-

ance and physical damage. If shipping damage has occurred,

immediately notify your dealer.

•The DMS80 has been specially designed with vents placed on the

bottom, sides and top of the metal cabinet. If you decide to place a

computer monitor on top of the DA80 and depending on the size of

your monitor’s support base, some or most of the top vents may be

covered by the monitor base.This is perfectly acceptable and will

not cause the DA80 to overheat.

•The M40 speakers were designed specifically for the DA80, but

other speakers can be used as long as the impedance is not less

than 6 ohms. Use of lower impedance speakers may damage the

DA80 or any equipment sitting on top of it. Low impedance speakers

will cause the DA80 to operate at higher temperatures, creating

sound distortion, and may damage the speakers.

•Do not expose the DA80 to dust or moisture and be sure to wipe it

clean of any dust regularly.

•Do not connect a non-amplified subwoofer speaker directly to the

DA80 or the warranty will be void. Damage may occur to sub out

line level output circuitry.

OPERATING NOTES

ENGLISH

1. POWER SWITCH

Depress the POWER switch to turn the DA80 on.The POWER LED

indicator will light when the power is on. Release the POWER

switch to turn the DA80 off.

2. MASTER VOLUME CONTROL

The MASTER VOLUME control regulates the signal level of the

LINE input, AUX/CD input and MIC/INST. input to the SPEAKER

OUTPUTS, SUB OUT and Headphone jack. However, it does not

affect the Line output level.

NOTE:Volume level is also affected by the volume of the signals

being fed into the DA80’s LINE inputs, AUX/CD inputs and

MIC/INST. input and level control setting. If normal listening volume

is not attainable, with the DA80’s MASTER VOLUME control set to

the mid position, adjust the signal source volume of the equipment

coming into the DA80.

3. BALANCE CONTROL

The BALANCE Control regulates the relative left and right levels of

the LINE, AUX and MIC/INST. inputs to the speaker and headphone

outputs.

4. FIVE BAND STEREO GRAPHIC EQUALIZER

Adjust the five center detented slide controls to customize the

sound to your personal preference or to compensate for acoustics in

the listening room. Each of the five EQ sliders will give you 12dB of

boost or attenuation in its particular frequency band and in turn will

affect the overall output signal of the DA80.

ENGLISH

60Hz: Boost to bring out kick drum, bass guitar or to add more low

end “punch”to a mix. Cutting this frequency can help clean

up a muddy sound.

250Hz: Adjusts the mid bass range. Boost to add “warmth”to vocals

and strings.The cello and the low strings of a rhythm guitar

fall into this range. Cut to eliminate overpowering low end.

1kHz: Boosting this range enhances vocals, snare drum and per-

cussive instruments, while cutting this range may make

vocals blend into the background.

3.5kHz: Boost to add “bite”to the guitar, vocals or solo instrument.

Cut this range to eliminate harshness.

12kHz: A proper adjustment here “brightens”the sound, while too

much high frequency can make the total sound effect sharp

and add unwanted noise and hiss.

5. SUB LEVEL CONTROL

The SUB (Sub Woofer) LEVEL slide control raises or lowers a mono

line level signal to the SUB OUT MONO output.The signal combines

the left and right inputs and passes through a low pass filter. Because

this is a line level signal, it must be used with a power amplifier and

subwoofer speaker or go directly to a powered subwoofer.

NOTE: The VOLUME control acts as a master level control. It regu-

lates the sound level of both the speakers and the subwoofer sys-

tem together.

6. LINE SWITCH

Depress the LINE switch to its On position to select the audio signal

from the LINE IN inputs. Release the LINE switch to its Off position

to mute the audio signal from the LINE IN inputs.

7. AUX/CD SWITCH

Depress the AUX/CD switch to its On position to select the audio

signal from the AUX/CD inputs. Release the AUX/CD switch to its

Off position to mute the audio signal from the AUX/CD inputs.

8. EQ SWITCH

Depress the EQ switch to its On position to activate the preset

EQUALIZER slide controls. Release the EQ switch to its Off position

to bypass the EQ circuitry.

CONTROLS AND FUNCTIONS

ENGLISH

9. MIC/INST. SWITCH

Depress the MIC/INST. (Microphone/Instrument) switch to its On

position to select the audio signal from the MIC/INST. inputs.

Release the MIC/INST. switch to its Off position to mute the audio

signal from the MIC/INST. inputs.This is used in combination with

the MIC/INST. LEVEL Control (see 11 below).

10. SOUND LEVEL METER

The sound level meter is used for visual monitoring of the sound

levels and signals being processed within the DA80.The meter is a

perfect tool for setting balance between the stereo channels or for

checking the DA80’s output level to the speakers.

11. MIC/INST LEVEL CONTROL

The MIC/INST LEVEL control regulates the volume of any micro-

phone or instrument plugged into the 1⁄4″MIC/INST. jack.

12. MIC/INST. JACK

The 1⁄4″unbalanced TRS MIC/INST. Jack is designed to accommo-

date high and low impedance microphones as well as electric

instruments.

13. HEADPHONE JACK

The 1⁄4″stereo headphone jack is designed for private listening and

automatically deactivates the speakers and sub mono out when

headphones are plugged into the headphone jack.

CAUTION: Check for accidental high volume settings. Serious injury

may result to the user’s hearing. Be sure not to plug in headphones

at any time unless the master VOLUME control is set to the position

marked MIN.

1. SPEAKER OUT

This push-spring terminal strip is the amplified output which powers

the speakers. Any non-amplified speakers may be used as long as

they are rated to meet a 6 ohm to 8 ohm impedance.There will be

no output when headphones are inserted into the headphone jack.

CAUTION: Be sure power to the DA80 is off before connecting the

speakers. Be sure none of the wire strands make contact with other

speaker terminals or the DA80’s protection circuitry will shut that

channel down and no sound will be heard until the wire is removed.

NOTE: Plugging headphones into the front panel headphone jack

will mute any signal to the SPEAKER OUTPUTS as well as to the

SUB OUT MONO output.

2. LINE IN

The LINE IN jacks accept audio signal input from any equipment

with line level outputs.This will include any keyboard or sound mod-

ule, line level from any mixer or the output of your computer’s sound

processing board. Use the provided shielded cable accessory for

connection.There is no separate volume for the LINE IN, so adjust-

ments to the equipment connected to the LINE IN jacks may be

necessary to balance them with equipment plugged into other

inputs.

ENGLISH

NOTE: Signals to the LINE IN will be amplified only when the LINE

switch on the front panel is depressed to its on position.

3. AUX/CD IN

The AUX/CD IN jacks accept audio signal input from any external

CD or CD ROM player, stereo receiver, audio mixer, video board or

VCR.

NOTE: Signals to the AUX/CD IN will be amplified only when the

AUX/CD switch on the front panel is depressed to its in position.

4. LINE OUT

The LINE OUT provides line level output of the LINE input, AUX/CD

input and MIC/INST. input signals, unaffected by the Master VOL-

UME Control, BALANCE Control or GRAPHIC EQUALIZER.

5. SUB OUT MONO

Connect the SUB OUT MONO output to the line in of an additional

amplifier and subwoofer or powered subwoofer system. Since sub-

woofer signals are normally mono, only one cable is used between

the DA80 and the subwoofer system.The SUB OUT MONO has

been designed to provide +6dB of line level output gain for a sepa-

rated amplifier or self contained subwoofer system equipped with a

built-in amplifier.

CAUTION: Do not connect a non-amplified subwoofer speaker

directly to the DA80’s SUB OUT MONO output or the warranty will

be void. Damage may occur to the sub line level output circuitry.

NOTE: Plugging Headphones into the front panel headphone jack

will mute any signal to the SUB OUT MONO output as well as to the

SPEAKER OUTPUTS.

6. FUSE

The fuse provides protection for the DA80.The fuse will blow if there

is an overload condition, high demand for power amplification or

extremely low speaker impedance. Replacement size is a standard

F3A miniature fuse (5mm x 20mm) for 115V systems or T2A for

230V systems. If a fuse continues to blow, please contact Samson

service at 1-800-3SAMSON (1-800-372-6766).

7. AC INLET

Connect the supplied standard 3-pin “IEC”plug to the AC INLET.
