Inter-m CA-6220 - Master Section 1 Controls

2. MASTER SECTION 1
1. LED LEVEL METER
This precision LED meters display the levels of
the signals output line output. These meters
serve as useful guides when setting optimum
output levels using the master stereo faders.
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, correspond-
ing 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 cor-
responding 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.
