SAFETY PRECAUTIONS

GENERAL GUIDELINE

1. When service is required, observe the original lead dress.
Components, wires or cables that indicate evidence of
overheating or other electrical or mechanical damage
should be replaced.

2. After servicing see to that all the protective devices, such
as insulation tape, shields must be properly installed.

3. After servicing, make the following leakage current
checks to prevent the customer from being exposed to
shock hazards.

LEAKAGE CURRENT COLD CHECK

1. Unplug the AC cord and connect a jumper between the
two prongs on the plug.

2. Measure the resistance value, with an ohmmeter,
between the jumpered AC plug and each exposed
metallic cabinet part on the equipment such as
screwheads, connectors, control shafts, etc.
When the exposed metallic part has a return path to the
chassis, the reading should be between 1M Ω and 5.2M
Ω. When the exposed metal does not have a return path
to the chassis, the reading must be ∞ (infinity).
Any resistance value below this range indicates an
abnormality which requires corrective action.

3. Repeat the test with the AC switch in the "OFF" position.

LEAKAGE CURRENT HOT CHECK

1. Plug the AC cord directly into adaptor socket and plug
adaptor into the AC outlet. Do not use an isolation
transformer for this check.

2. Connect a 1.5k Ω/10W resistor, paralleled by 0.15 µF
capacitor, between each exposed metallic part on the unit
and a good earth ground such as a water pipe, as shown
in Figure 1.

3. Use an AC voltmeter, with 1000Ω/volt or more sensitivity,
to measure the potential across the resistor.

4. Check all exposed metallic parts of the cover (BNC
connector, Handle bracket, Metallic cabinet, Screwheads,
Metallic overlays, etc.), and measure the voltage at each
point.

5. Reverse the AC plug in the AC plug adaptor and re-peat
each of the above measurements.

6. The potential at any point should not exceed 0.75 V RMS.
A leakage current tester (SIMPSON MODEL 229 or
equivalent) may be used to make the hot checks.
Leakage current must not exceed 0.5 milliampere.
In case a measurement is outside of the limits specified,
there is a possibility of a shock hazard, and corrective
action must be taken before returning the instrument to
the customer.

Channel numbers

There are sixteen Channel Fader Strips on the

DA7

.
Depending on the selection of the four Fader Layer
controls, each strip directly controls (1) INPUT 1-16, (2)
INPUT 17-32, (3) AUX/BUS (indicated on the bottom of the
strip), and (4) a user CUSTOM/MIDI function.

The MIC/LINE INPUT knob varies the channel input gain
volume and adjusts for either a mic or line-level input. Due to
the high quality design of this circuit, there is no pad switch
necessary; the input knob range sets the input level. This
knob only affects the analog inputs 1-16.

The

PEAK/SIGNAL LED

indicates when an input signal is

present (

green

), and when the input signal level is too high

(

red

).

The LED field indicators reflect the auxiliary (AUX) routing
assignments and automation parameters. The LED color
signifies the AUTOMATION/AUX button selection; AUX
(

green

), AUTOMATION (

red

).

The SOLO LED button toggles on (

red

) or off. When on, the
channel output will be routed to the MONITOR A speakers
(overriding the MONITOR A input), and to the headphones.

The FLIP LED button flips the control of the Channel Fader
Strip from one input layer to the other. The LED color
indicates the current input selection and matches the Fader
Layer control LED button colors, INPUTS 1-16 (

green

) or

INPUTS 17-32 (

red

).

The SELECT LED button, when on (

orange

), identifies the
channel as the current channel selected. Only one Fader
Strip can be selected at a time (unless it’s in stereo or link
mode).

For more detail, see Chapter 5, Channel, Library, and
Meter Windows in the Users' Guide.

The ON LED button toggles on (

red

) and off. When on, the

channel output is active.
There are two channel numbers for each strip, indicating the

INPUT connections on the Rear Panel of the

DA7

.

The AUX/BUS label at the bottom of a Channel Fader Strip
indicates its function when the AUX/BUS Fader Layer
control is selected.

See Chapter 6, Fader Layers and Channel Strips in the
Users' Guide for additional information.

AUTOMATION/AUX LED Button

The AUTOMATION/AUX LED button toggles the display of
the Channel Fader Strips LED field indicators. The LED
color indicates the current selection.

See Chapter 14, Automation and Chapter 10, AUX in the
Users' Guide for additional information.
