1. MONO INPUT SECTION

1. PEAK LED INDICATORS

This LED indicators let you check the level of the signal
input to the channel.
The peak indicator lights when the input signal reaches
3dB below the channel’s clipping point.
This indicator show the level of the post-EQ/pre-fader
signal. If the PEAK indicator lights more than briefly on
high-level transients, you should use the TRIM control to
decrease the input sensitivity of the channel.

2. CHANNEL LEVEL

This is the channel’s main level control. It determines the
level of the signal that is sent from the channel to the
master mixing and effect buses. It is the settings of the
input channel levels that determine the “mix”, or the
balance of sound levels between the instruments or other
sources connected to the input. When a channel is not
being used, its level should be set at the minimum posi­tion to prevent the addition of unwanted noise to the
main program signal.

3. PAN

This control pans the channel signal across the master L
and R buses, thus determining the perceived position of
the sound from that channel in the output stereo sound
field. If a PAN control is set all the way to the left, for
example, the sound from that channel will be heard from
the left-speaker system only. If it is set all the way to the
right, the sound will be heard from the right speaker
system only. Intermediate settings will cause the sound to
appear at corresponding locations in the stereo sound
field.

4. EFF1/MONI

This control determines the level of the post-EQ/pre-

EFF1/MON mixing bus. The channel signals mixed by this bus have their overall level set by the EFF

channel level signal that is sent from the channel to the

SEND 1 fader and MON fader, then are sent to the EFF SEND 1 jack and MON jack. The output from
EFF SEND 1 jack can be processed by an external effect device.

5. EFF2/REV

This control determines the level of the post-EQ/post-channel level signal that is sent from the channel
to the EFFECT 2 mixing bus. The channel signals mixed by this bus are sent via the EFFECT SEND 2
fader to the EFFECT SEND 2 jack. The output signal is also fed into CA-6220/8220’s internal digital
signal processor. Thus, a signal fed to the EFFECT 2 bus using this control can be processed externally
or internally.

6. EQUALIZER CONTROL

This set of three controls allows you to individually modify the channel’s response. Each channel of the
CA-6220/8220 is equipped with a three-band equalizer (EQ) that has shelving HIGH and LOW con­trols, and a peaking MID control.
Refer to “Using the Channel Equalizers” for detail on the use of these controls.

7. TRIM

This control adjusts the channel’s input sensitivity between –60dB and –16dB at XLR jack operating or
between –40dB and +4dB at 1/4” phone jack operating on front panel. Continuously variable trim con­trol allows optimum adjustment to virtually any microphone or line source.

8. BALANCED LINE INPUT CONNECTORS

A standard 1/4” phone jack is used for balanced or unbalanced line level signals. Examples of line lev­el signals include most electronic keyboards, synthesizers, turntables (with appropriate preamps), tape
decks and the line outputs from other mixers. All input channel controls, including the variable gain con­trol, affect the LINE input.

9. BALANCED LOW-Z MIC INPUT CONNECTORS

A 3-pin XLR-type connector is used for balanced low impedance microphone input. (pin 1: sleeve, pin 2:
hot, pin 3: cold)
Microphone of 50~600Ω or 600Ω line level devices can be connected here. When the PHANTOM
switch is turned on, DC +48V will be supplied to pin 2 and 3 of these connectors.

2. 9-BAND GRAPHIC EQUALIZER

The CA-6220/8220’s internal stereo graphic
equalizer (GEQ) allows fine response shaping
of the main program output. These section has
nine linear controls per channel, correspond­ing to center frequencies of 63Hz, 125Hz,
250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz and
16kHz. Each control permits a maximum boost
or cut of 12dB. When a control is set to the
center or “0” position, the response in the cor­responding band is unaffected.

3. MASTER LEVEL

These are the main volume controls for the overall program mix. They independently adjust levels of the
right and left channels of the stereo signal that is sent to both the rear-panel SPEAKER jacks and the
PHONES jack of the line out on the front panel.

4. LINE OUT JACKS

LINE OUT L jack is delivered by summing all of the inputs assigned to the left subgroup bus. A pan control
rotated fully counterclockwise to the “L” position will assign that signal only to the left bus. LINE OUT R jack
is the right subgroup equivalent of the LINE OUT L. The signals are sent at a normal level of +4dB.

5. AMP IN JACKS

When you connect a plug to this jacks, you disconnect the power amplifier input from the graphic
equalizer output or line output. And the power amplifier is drived by the signal through the inserted plug.

6. TAPE TO MON AND TAPE TO EFF CONTROLS

These controls adjust the level of the stereo signals from a connected tape deck to MONITOR and EFFECT
SEND jacks respectively.

7. REC OUT AND TAPE IN CONTROLS

These controls adjust the levels of the stereo signals to and from a connected tape deck. The REC OUT
control sets the level of the unequalized pre-fader master mix signal that is sent for recording by the tape
deck via the REC OUT jacks. The TAPE IN control adjusts the level of the playback signal that is inserted to
the master mixing bus from the TAPE IN jacks.the GEQ. The level of these signals are adjusted by the
REC OUT and TAPE IN controls.

8. REC OUT AND TAPE IN JACKS

These phone jacks are used to send stereo signals (–10dBV) to and from a connected tape deck. The
REC OUT jacks send the unequalized pre-fader signal from the master bus for recording by the tape
deck.
The TAPE IN jacks connected the playback signal from the tape deck to the master mixing bus in front of
the GEQ. The level of these signals are adjusted by the REC OUT and TAPE IN controls.

1. DIGITAL EFFECT SECTION

This section lets you control the CA-6220/8220’s
internal digital signal processor. The ON switch
selects between input from the internal DSP and
input from the EFFECT RETURN 2 jack.

2. EFFECT SEND CONTROLS

These controls adjust the overall output levels of the
effect mixes that are set up using the EFFECT 1 and
EFFECT 2 controls of each input channel. The EFFECT
SEND 1 control sets the overall level of the signal that
appears at the EFFECT SEND 1 jack. The EFFECT
SEND 2 control sets the overall level of the Effect 2
mix signal, which is sent to both the EFFECT SEND 2
jack and the internal digital signal processor. These
controls should be used to optimally match the effect
mix output levels to the input sensitivities of the effect
signal processors used.

3. EFFECT RETURN JACKS

The output from external effect units fed by the
EFFECT SEND jacks can be returned to the main pro­gram mix via these 1/4” phone jacks. Note that both
effect circuits have stereo EFFECT RETURN jacks,
allowing the CA-6220/8220 to accommodate effect
devices with stereo output. To return a monophonic

effect signal to both channels of the master stereo
mixing bus, use the EFFECT RETURN L jack. (The R jack should be left open.) The level of the signals input
by these jacks are adjusted by the corresponding EFFECT RETURN controls. The nominal input level for
these jacks is +4dB.

4. EFFECT SEND JACKS

These 1/4” phone jacks deliver the corresponding effect mix signals to feed external effect devices. Note
that the EFFECT SEND 2 output is active even when the internal digital signal processor is turn on. The
levels of the signals output by these jacks are adjusted by the corresponding EFFECT SEND controls. The
nominal output level for these jacks is +4dB.

Operating Tips

Operating Tips

CAUTIONS FOR CONNECTED SOURCESS

Please observe the following cautions when connecting sound sources to the CA-6220/8220.

- TURN THE POWER OFF FIRST
Always make sure that the mixer’s POWER switch is turned off before connecting or disconnecting any
cables. Failure to do so can damage the CA-6220/8220 or connected equipment.

- TURN THE MIXER ON LAST
Always turn the mixer’s POWER switch on after first turning on connected sound sources such as electron­ic instruments or audio equipment.

- DO NOT CONNECT AMPLIFIED INPUT
Never connect the speaker-level output of any amplifier to the mixer’s inputs unless you use a suitable
high-level attenuation pad or “direct box” to lower the signal’s level.

USING THE CHANNEL EQUALIZERS

Each of the CA-6220/8220’s input channels has three equalizer (EQ) controls that make it possible to
independently equalize the channel’s signal to some degree. The rule of thumb, however, is that equaliza­tion should not be used unless it is absolutely necessary. Always put some effort into proper microphone
selection, careful microphone placement, and fine adjustment of source instrument controls before resorting
to equalization. Settle for this option only if you have set everything up as best you can and are still not sat­isfied with the sound.

Channel equalization can be most useful in tonally separating one sound from another, or from a group of
sounds. Slightly boosting the high frequency of a guitar sound, for example, can give it the extra bite it
needs to stand out more clearly from the background. Vocals tend to stand out better if given a bit of boost
in the middle range. Speech generally benefits from a reduction in the low frequencies, to prevent the
“boomy” sound that occurs when the speaker gets too close to the microphone. Experimentation and
experience will tell you how much of what type of equalization is appropriate for different sound sources.

Also keep in mind the fact that the channel’s PEAK LED indicator is post-EQ. Excessive boosting of a signal
frequency may cause the PEAK LED to light more than briefly, indicating that you need to either reduce the
input gain or reduce the amount of boost being applied.

CA-6220/8220

STEREO POWERED MIXER

USING THE GRAPHIC EQUALIZER

The CA-6220/8220’s built-in graphic equalizer (GEQ) has two main uses: compensation for acoustic defi­ciencies in the listening area, and feedback control. Like the channel equalizers, the GEQ should not be
used unless it is absolutely necessary. The more equalization you use, the more phase deviation you intro­duce into the program signal–and the greater the chance that the phase deviation can result in an unnatu­ral, distorted sound.

There are many instances, however, in which the acoustic characteristics of the listening area cause
response anomalies. Large areas of uncovered glass or tiled floors, for example, are extremely effective
reflectors of high-frequency sound. Amplified sound produced in such environments can seem painfully
sharp, in which case some reduction in the high-frequency range may be called for.

Smaller symmetrical rooms (a square room being the worst case) can actually have resonant frequencies
within the audible low-frequency range. In such rooms, a slight reduction in the low frequencies can help to
clarify the sound. Please note that in almost all cases, good equalization demands a cut in the offending
frequency range rather than a boost in ranges where response is lacking.

The GEQ can also be used–although to a limited degree–to control feedback. Proper microphone place­ment is the primary means of preventing feedback, but this can be extremely difficult if you’re working in a
tight stage area. To get around this problem, try cutting response in the frequency range where the feed­back is occurring. (You may have to experiment a bit to find this range.) This solution will compromise the
overall frequency response of the program, but it is better than running the risk of squealing feedback in
the middle of an important performance.

CONNECTING SPEAKERS

The CA-6220/8220 Powered Mixer have 1/4” phone jack and speakon speaker outputs per channel. The
outputs for each channel are connected in parallel internally. This places some restrictions on their use, as
described below:

- If you connect speakers to only one of the output jacks on either channel (R or L), the total impedance of
the speaker system connected to that channel may be no less than 4 ohms.

- If you plug speakers into both jacks of either channel (R or L), the total load impedance of the speaker sys­tems connected to each output of that channel must be no less than 8 ohms. (Note that two 8-ohm speaker
systems connected in parallel form a 4 ohm load).

- The maximum total impedance of speakers connected to the speaker outputs of each channel should be
16 ohms.

- The maximum speakers allowable per channel are: one 4-ohm speaker, two 8-ohm speakers, or four 16­ohm speakers.

Although a higher total load impedance than the recommended 16 ohms will only result in a loss of power
output, a total load impedance that is too low can actually damage the CA-6220/8220.

- Never connect or disconnect speakers while the mixer’s power supply is turned on!

USING THE DIGITAL SIGNAL PROCESSOR

The CA-6220/8220’s built-in digital signal processor (DSP) features 16 top-quality digital effects. Each
effect program has one parameter that can be edited to modify the sound of the effect. The table below lists
the programmable parameter and its possible values for each program. Use the ON switch in the DIGITAL
EFFECT section to turn the internal DSP on and off. The EFFECT RETURN 2 controls will adjust the level of
the signal output by the internal DSP, and any input signals to the EFFECT RETURN 2 jacks will be ignored.
