AUTOGRAM MINI-MIX AUDIO CONSOLES
Mini-Mix 8A, Mini-Mix 12A
INSTRUCTION MAllftJAL
SECTION l
INTRODUCTION
The Mini-Mix consoles are full-functioned professional broadcast
audio mixing systems. Space and cost saving measures have
yielded a small package along with an attractive price without
giving up the features needed in today's active broadcast studio .
BASIC FEATURES
INPUT
The Mini-Mix consoles feature either eight or twelve channels :
the first two are dedicated to microphones while the remaining
channels provide 2 stereo inputs each (channel 12 on the Mini-Mix
12A has a total of 7 stereo inputs). Each channel may be as-
signed to either Mix Bus One and/or Mix Bus Two. Both buses may
be fed simultaneously .
The slide faders operate with D.C. only and drive an associated
V.C.A. (voltage controlled amplifier) for level control.
A unique feature of the Mini-Mix consoles is that the "A" input
is an electrically-balanced professional-type while the "B" input
uses PHONO-JACKS to be directly compatible with consumer-type
equipment.
The balanced inputs use a miniature plug-in screw-type connector
which makes installation very simple. Sources may be moved
around easily for different configurations. Each balanced input
is user-adjustable to accept levels between -15 dBv and +15 dBv.
A balanced adjustable input is provided for connecting an exter-
nal air-monitor source.
The microphone inputs use convenient XLR type connectors and fea-
ture PAN POTS. The pan pots may be disabled if this feature is
not desired. A front panel switch turns the microphone channel
ON and OFF whi 1e activating the "Mute" circuit when the channel
is "on". The muting may be programmed for either microphone
channel.
OUTPUT
Balanced and unbalanced outputs are provided for the two mixing
buses. As with the inputs, the balanced outputs use miniature
plug-in screw-type connectors while the unbalanced outputs use
phono jacks.
A balanced output is provided for the MONO sum of Mix bus 1.
l

STEAM POWERED RADIO.COM
MONITORING
Separate select switches and level controls are provided for the
headphone and monitor circuits. Bus 1, Bus 2, or an external Air
signal may be selected. An external monitor power amplifier is
required which may be whatever power range desired. The monitor
driver output is on phono jacks and is compatible with consumer
type amplitiers. Muting for the monitor output is included and
may be programmed to operate from either microphone channel. The
headphone outputs appear on two standard 1/4 inch phone jacks and
are designed to accommodate modern higher impedance headphones
with ample volume.
A cue speaker and amplifier are built-in to provide cue monitor-
ing. A front panel switch on non-microphone channels select CUE .
When CUE is selected, that channel will be removed from the out-
put buses.
METERING
Four LED bar graphs provide visual indication of output level for
the Left and Right channels of Bus 1 and Bus :2. A special cir-
cuit enables the graphs to respond with "ballistics" which are
similar to the standard Vu meter. Additional LEDs are used to
give indication of an Overload condition (10 dB above 0
reference, adjustable) and are designed to give fast response to
audio peaks.
OTHER FEATURES
Front edge switches provide dry contacts which can be used for
remote starting equipment or for other purposes. Connection for
the switches is on a rear mounted Sub-D type connector.
An internal relay is included to activate On-Air lights and may
be programmed to either microphone channel. The relay follows
the monitor muting assignments.
A small jack is provided to give access to the cue output. When
a
plug is inserted into the jack, the internal cue speaker will
be disabled.

SECTION 2
INSTALLATION
The Mini-Mix consoles are small enough to be installed in almost
any location and may be used in permanent as well as temporary
situations. The Mini-Mix consoles can be used at remote sites
and in remote vehicles.
POWER SUPPLY CONNECTIONS
The Mini-Mix power supply can be mounted up to eight feet from
the console. A shielded interface cable is provided for this
purpose. Unless requested, the power supply is wired for 115
v.a.c./ 60hz mains . The transformer can be rewired for 230
v.a.c./ S0hz mains.
BEFORE APPLYING POWER
Connect each end of the shielded power supply cable .
* THE CONNECTOR AT THE CONSOLE END IS INVERTED AND WILL*
* PLUG IN UPSIDE DOWN. *

MICROPHONE CONNECTIONS
Any standard balanced low-impedance microphone may be used wi th
the Mini-Mix console; however, the preamplifiers are opt i mized
for 150 ohm source impedances . Pin 3 on the XLR connector is
considered high or + whi 1e pin 2 is 1 ow or - . Pin 1 is gr o und.
An unbalanced microphone can be used by wiring the center conduc-
tor to pin 3 and the shield to pin 1 .
PAN POTS
The pan pots are used to adjust the position of the microphone
sound in the stereo image. Turn the pot to the left to make the
microphone appear to the left; turn the pot to the right to po si-
tion the sound to the right . This feature is useful for in t er-
views where the interviewer might appear on the left channel and
the subject on the right.
To DISABLE the pan pot, remove the screws along the underside of
the front panel lip . The front panel can then be raised up ( it
is hinged at the rear) . There are jumper-headers located near
each microphone pre- amplifier (refer to main parts layout draw-
ing MM1021). Simply move the jumper to the other pin or just
remove the jumper.
Muting of the monitor and the mute relay will be covered later .
BALANCED INPUT CONNECTIONS
(Refer to drawing at the end on this section for conne ct or
hookup.)
Balanced professional equipment can be connected to the plug-in
screw-type connectors on the non-microphone. Levels between -15
dBv and +15 dBv may be accommodated. The inputs are 20k ohm
bridging. If a terminated input is required, a 600 ohm resistor
must be placed on the connector along with the wiring for both
l eft and right channels. To connect a mono source , simply c on-
nect to the left channel then jumper to the right channel .

After the sources are connected, the levels may be trimmed by
means of the small pots which are located on either side of the
balanced input connector and are accessible through the resp e c-
tive sma 11 holes. A 3/ 32 inch "Greeni e" screwdriver works
n icely for adjusting the Mini-Mix input levels .

The balanced outputs for the Mini-Mix consoles are calibrated at
the factory for +8 dBm into a 600 ohm load. The actual output
impedance is approximately 100 ohms. Internal master gain con-
trols allow the output to be adjusted to another reference value;
however, the metering system will require re-calibration if these
levels are changed . Do not ground either+ or - output terminal.
If an unbalanced feed is required, use the+ termina l and ground.

MONO OUTPUT
The balanced MONO output provides the monaural sum of Busl . The
output characteristics are identical to the main bus outputs. A
level control is located adjacent to the connector.
TELEPHONE INTERFACE
The MONO output may be used for interfacing to a telephone sys-
tem. In this case use Bus 2 as the main output and use Busl as
an assignable MIX-MINUS output. Do not ground either+ or - out-
put terminal. If an unbalanced feed is required, use the+ ter-
minal and ground .
A telephone interface unit is required to connect the console to
the telephone line .

UNBALANCED OUTPUT CONNECTIONS
Unbalanced outputs are provided for BUS 1 , BUS 2 , and MON ! TOR.
These outputs will interface directly to consumer type equipment .
While a cue speaker is built in, it may be desirable t o employ a
larger speaker or a more powerful external amplifier and speaker.
An 1/8 inch mini-phone jack is provided to allow access to the
cue amplifier output. When a plug is inserted into this jack,
the internal cue speaker wi 11 be disconnected. The 1 evel wi 11
still be adjusted by the CUE GAIN control.
AUXILIARY FUNCTIONS
MUTING ASSIGNMENTS
Muting for the MONITOR output as well as activation of the mute
relay can be programmed to operate from either microphone chan-
nel.
The Sub-D male connector (supplied) must be inserted into the
proper connector on the rear panel to allow muting . The connec-
tor is factory wired to provide muting for both microphones .
Refer to the wiring tables if a different configuration is re-
quired.
MUTE RELAY CONNECTIONS
Contacts for the MUTE RELAY are brought out to the REMOTE START
connector on the rear panel. These contacts can be used to ac-
tivate an ON AIR light. Refer to the wiring tables for connec-
tion information.
*CAUTION*
THE RELAY CONTACTS
ARE RATED FOR 1 AMP D. C. AND 25 WATTS A.C
ONLY . IF LARGER LAMPS ARE TO BE USED AN EXTERNAL CONTROLLER MUST
