Aphex Studio Dominator 700 - 10 Test Procedures; Main Board

10.0
TEST AND ALIGNMENT PROCEDURES
The Studio Dominator is an interactive device, with many of
the circuits depending on and working with others. Therefore,
the following test procedure should be used in its entirety
only, as a spot test of a single function may not provide valid
information.
10.1 MAIN BOARD
10.1.1 Power-Up
a. Apply power and immediately check for overheating
of the output transistors. Also look for other
possible signs of power rail overloads.
b. Check all LED's and mechanical operation of the
pushbuttons.
10.1.2 Beginning Settings
a. DRIVE pot full CCW.
b. RELEASE TIME full CWo
c. Equalizers CENTER.
d. All pushbuttons GREEN.
e. TEC off.
f. OUTPUT CEILING at +6.
g. INPUT LEVEL SELECT (internal) set at -10
10.1.3. Input Stage Test
a. Feed -10dBm 1kHz into both channels.
b. Measure the level at H504 jumpers 1-2 for left
channel and 10-11 for right channel. The
level should be OdBm ~ 1/2 dB. Left and right
should be equal within + O.2dB .
c. Switch the input level switches to +4 position.
The level at the jumpers should drop 13dB and
still match within + O.2dB.
