Place of Purchase

Selecting fine audio equipment such as the unit you've just purchased is only the start of your musical enjoyment. Now it's time to consider how you can maximize the fun and excitement your equipment offers. VocoPro and the Electronic Industries Association's Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or distortion and, most importantly, without affecting your sensitive hearing.

Sound can be deceiving. Over time your hearing “comfort level” adapts to a higher volume of sound. So what sounds “normal” can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.

To establish a safe level:

• Start your volume control at a low setting.
• Slowly increase the sound until you can hear it comfortably and clearly, and without distortion.

Once you have established a comfortable sound level:

- Set the dial and leave it there.

- Pay attention to the different levels in various recordings.

Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we want you listening for a lifetime.

Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since hearing damage from loud noise is often undetectable until it is too late, this manufacturer and the Electronic Industries Association's Consumer Electronics Group recommend you avoid prolonged exposure to excessive noise. This list of sound levels is included for your protection.

Some common decibel ranges:

Level	Example
30	Quiet library, Soft whispers
40	Living room, Refrigerator, Bedroom away from traffic
50	Light traffic, Normal Conversation
60	Air Conditioner at 20 ft., Sewing machine
70	Vacuum cleaner, Hair dryer, Noisy Restaurant
80	Average city traffic, Garbage disposals, Alarm clock at 2 ft.

The following noises can be dangerous under constant exposure:

Level	Example
90	Subway, Motorcycle, Truck traffic, Lawn Mower
100	Garbage truck, Chainsaw, Pneumatics drill
120	Rock band concert in front of speakers
140	Gunshot blast, Jet plane
180	Rocket launching pad

Operations Cont.

Microphone Operations

Adjusting the Independent Volume controls

When there are multiple vocalists present it is common that some will sing louder than others. The volume levels for each pair of mic channels can be adjusted independently to create a balanced vocal mix.

• Mic Volume 1 controls MIC 1 Input (front panel) and MIC 1/B Input (rear panel)
• Mic Volume 2 controls MIC 2 Input (front panel) and MIC 2/B Input (rear panel)
• Mic Volume 3 controls MIC 3 Input (front panel) and MIC 3/B Input (rear panel)

To adjust the independent microphone volumes:

Turn the volume control clockwise to increase the volume and counter-clockwise to decrease the volume.

Adjusting the Master Microphone Level

Once you have balanced the individual mic channels you can use the Mic Master Level control to adjust the overall mic level.

To adjust the Master Microphone Level:

Turn the volume control clockwise to increase the volume and counter-clockwise to decrease the volume.

Adjusting the Microphone Pan

The Pan control on the front panel allows you to balance the microphone vocal output between the left and right channels. Adjust the pan until you find the best sounding mix for each situation. In most cases it will be sufficient to set the Pan control in the center position.

• Turn the control all the way left to output vocals to the left channel only
• Set the control to the center position to output vocals evenly between both left and right channels
• Turn the control all the way right to output vocals to the right channel only

Adjusting the Microphone Tone

The DA-1055 PRO allows you to adjust the overall Low, Mid and High EQ of the microphone vocals for a more professional and clear vocal tone.

• LOW EQ: Use this control to increase of decrease the amount of "low end" or Bass present in the vocals. Too much bass may sound "muddy" or dull. Turn clockwise to increase the low end and counter clockwise to decrease the low end.
• HIGH EQ: Use this control to increase or decrease the amount of "high end" or Treble present in the vocals. Too much treble may sound "tinny" and could be the cause of feedback. Turn clockwise to increase the high end and counter clockwise to decrease the high end.
• MID SWEEP: Use this control to determine which Mid Frequency will be present in the mix. Since the frequency ranges from the MID SWEEP are from 250 Hz to 6K Hz, this is particularly versatile for vocals, and enabling particular characteristics of the singer to be lifted or suppressed.
• MID EQ: Use this control to increase or decrease the Mid Frequency that is selected by the MID SWEEP control.

Operations Cont.

Using the Digital Echo (microphone only)

Turning on Echo:

1. Press the ECHO button on the front panel IN to turn Echo on.
2. Press the ECHO button OUT to turn Echo off.

Adjusting the Echo settings:

The DA-1055 PRO allows you to adjust the Repeat and Delay of the Echo effect.

Repeat: The interval time between each repeat. Turning this up (clockwise) increases the time between each repeat and turning this down (counter-clockwise) decreases the time between each repeat.

Delay: The length of the overall echo. Turning this up (clockwise) causes the echo to last longer and turning this down (counter-clockwise) shortens the overall time of the echo.

7-Band Equalizer Operations

Adjusting the 7-Band EQ

The Dual 7-Band Equalizers allow you to adjust the music tone independently for the left and right channels. Every room is different and requires unique EQ settings to produce an optimum sound. Adjust the EQ until you find the desired tone for the source music.

The following is a general idea of how to use each of the bands however there is no “correct” setting as each performance situation is unique.

64 Hz - Fattens up the sub/bass tones or bass "rumble". Generally this is only necessary when using a subwoofer and the low end is more prominent in the mix.

160 Hz - Controls the mid-range of the bass/low end.

400 Hz - Controls the mid to low frequencies.

1 K - Controls the vocal presence, guitars and anything else in the middle frequency range.

2.5 K - Controls the more percussive, higher pitched sounds such as snare drums as well as the higher aspects of the vocal signal.

6.4 K - Controls the harmonic values of an instrument and is also useful for defining reverb when present.

16 K - Controls the highest frequency that is audible to the ears and affects the "shininess" in the mix.

NOTE: The 7-Band Equalizers do not affect microphone output.

NOTE: Use the LINE OUT RCA jacks to output the equalizer channels independently from the microphone channels.
