Mounting the Console to the Leg Stand
This SP-8 series console comes supplied with a factory leg support. The
console leg furniture consists of four pieces:
two end panels – the curved edge goes towards the front (armrest) of the
console.
front spanning panel – this mounts between the two side panels, just ahead
of the vertical center aluminum brackets. The narrow finished wooden strip
(cherry) is the bottom; the wider unfinished (pine) strip is the top.
rear spanning panel – mounts between the two side panels, along the rear
edge. The rear panel differs from the front panel in that it has been pre-drilled
with four 1/4" holes that accept enamel-finished #10 machine screws that go
into four tapped holes on the side panels' rear vertical brackets. Note when
correctly mounted into place there is a 5/8" gap between the bottom of the rear
panel and the floor to allow console wiring to exit the leg assembly. Once again,
the finished wood strip is the bottom; the wider pin strip is the top.
The SP-8 leg stand has been pre-assembled at the factory and then broken
down for shipment. All assembly holes have been pre-drilled. To re-assemble
the leg stand:
(1) attach the two side panels to the front spanning panel, using the eight
screws provided. The bottom of the panel should flush with the floor and the
bottom edge of the side panels. The side panel curves should face front.
(2) Attach the rear spanning panel to the side panels' rear vertical brackets,
using the finished #10 screws provided. Note the finished wooden edge of the
panel (cherry) should be along the lower edge approximately 5/8" from the
floor. (This step "squares up" the leg assembly and readies it for the console.)
(3) Remove the SP-8 console's rear concealment panel and place the console
on the leg stand, with the armrest facing forward. Note the console wooden end
pieces just straddle the leg stand side pieces. Roughly align the console front
to back so the rear edge of the console side pieces are roughly even with the
back edge of the leg stand side pieces.
(4) Remove the leg stand rear spanning panel to gain access to the underside
of the console.
(5) Note the wooden bottom of the console has been pre-drilled to accept
screws coming up through the top of the front spanning panel and to accept
screws from two rear side brackets already pre-attached to the leg side pieces.
If necessary, make a final front-to-back adjustment of the console so the holes
on the brackets and spanning panel pine strip line up with the pre-drilled holes
in the bottom of the console.

THE CONSOLE POWER SUPPLY
The power feed recommended
in the text is often installed and
referred to in studios as an
"isolated AC ground" outlet.
It is usually orange in color.
The console power supply is a standard 19" rackmount unit. It should be
mounted in an adjacent equipment rack within 15 feet (but preferably no closer
than 3 feet) of the console. The mounting location should allow proper air
circulation around the unit. Avoid locating any high gain equipment (such as
phono preamps, tape recorders, etc.) too near the power supply, to avoid
magnetic interference into that equipment.
The power supply is fitted with a 3-wire grounded AC cord that should be
plugged into a clean 120V AC outlet (that is, an AC source that feeds only the
control room audio gear). This AC source should be a separate feed from those
powering lighting, air-conditioning, or any other non-audio machinery. The
third pin ground wire of the AC source should be tied to the central system
ground point (see SYSTEM GROUND below).
With the power supply in place, plug in the AC power cord. Note the power
supply uses a 3-amp slo-blo fuse (back of chassis). The five LED indicators on
the supply's front panel should light up (PHANTOM, +V, –V, +5V, and +24V).
Unplug the power supply and connect it to the console, using the supplied
multi-conductor cable. Note the cable plugs into the back of the supply chassis
and into the bottom of the console (righthand end). With the console connected,
re-energize the power supply. The display indicators should again light; the
console's VU meters should light up, and individual module ON/OFF switches
and green CUE LEDs will power up randomly.
Dual Failsafe Supply
Your console may have been ordered with a dual failsafe option; in this case
you will have two separate rackmount supplies. If this is the case, then connect
both supplies to the console with the two cables supplied. Note that both
supplies must be energized for the failsafe function to work.
The first major installation step is to make sure the console is properly
grounded. Unplug the power supply, and proceed with the next section,
"System Ground".

INSTALLATION
SYSTEM GROUND
Safety requirements dictate that a positive connection from the console
mainframe to electrical ground be made in the completed installation.
The system ground serves two important purposes:
(1) Provides a zero signal reference point for the entire audio system;
(2) Assure safety from electrical shock.
There exist two terms that one encounters in a discussion of ground:
(A) EARTH GROUND, which is usually a heavy copper rod driven into
the soil adjacent to the building (around 6 feet down) or a connection
to the copper water pipes leading into the building. Either is
acceptable, unless, of course, the water pipe is plastic.
(B) THE POWER COMPANY EARTH CONDUCTOR that enters the
building at the power line breaker box; this conductor should be
(and is often by code) tied to the above-mentioned earth ground at
one point. This point is the SYSTEM EARTH GROUND.

TYPICAL SYSTEM
GROUNDING SCHEME
The grounding point on SP-8 consoles is a terminal lug strip located on the
bottom of the mainframe, near the power connector. This is the central
grounding point for the console mainframe. TIE THE CONSOLE
MAINFRAME TO THE SYSTEM EARTH GROUND. TIE EVERY PIECE
OF EQUIPMENT IN THE ENTIRE AUDIO SYSTEM TO THE CONSOLE
MAINFRAME GROUND. If the system earth ground point is inaccessible, tie
the console ground mainframe ground to the power company earth conductor
at the main breaker box.
SP-8 / Dec 95
Page 1 - 5

INSTALLATION
The aforementioned "isolated
AC ground" (orange studio
outlet; see page 2-2) can also
be used to accomplish the
required grounding.
Each piece of equipment should be connected by its own ground wire
(usually the round third pin on the AC cord). This means that every AC outlet
must have a separate conductor run to the console ground lug terminal; the
outlets cannot be daisy-chained as is normally encountered in commercial and
residential AC systems. Any equipment not supplied with 3-wire AC cables
must have individual ground wires (16 gauge or larger) connected to their
chassis grounds and then run to the console mainframe ground.
Further Grounding Details
Check all equipment to be absolutely certain that each unit is power
transformer isolated from the AC mains to prevent safety hazards.
It is assumed that in each piece of audio equipment the audio ground and the
chassis are tied together at some point. Any piece of equipment lacking a
grounded chassis is likely to be prone to interference problems.
Locate all unbalanced audio equipment in the same rack if possible, to
minimize chassis ground potential differences. It may also be helpful to
insulate each piece of unbalanced equipment from its mounting rails in the rack
by means of nylon 10-32 screws and insulating washers between rails and
faceplates.
Once the system is properly grounded, you may proceed with the audio
and control input/output connections (next chapters).

Front Panel Controls
From top to bottom, the individual module controls are as follows:
PAD switch — Attenuates (–20dB) the signal feeding the microphone input;
used to control extremely loud source material and prevent it from overloading
the module's microphone input circuitry.
MIC GAIN pot — Continuously variable; used to match input levels from
one module to the next.
+48V switch — Switches microphone phantom power on and off.
MIC/LINE switch — Selects between microphone or line input connectors.
LINE TRIM pot — Center detented, +/–15dB, allows continuously variable
adjustment of line input levels.
PHASE switch — Reverses the polarity of both mic and line inputs.
HPF high pass filter switch — Introduces a high pass –12dB/octave roll-off
at 125Hz; used for removing unwanted low frequency content from input
source signals.
EQ — 3-band semi-parametric with one concentric control for each band.
Each band continuously variable +/–16dB with continuously variable center
frequency. Frequency ranges are high: 800Hz–16KHz; mid: 400Hz–8KHz;
low: 40Hz–1KHz. Equalization curves are reciprocal, allowing previously
applied equalization to be subsequently removed.
EQ IN switch — Switches the 3-band EQ controls in and out of the circuit
(does not affect HPF switch).
PAN pot — Pans the module's mono signal between the left and right
channels of the console's stereo output (L/R assign switch must be engaged; see
below)
BUS ASSIGN switches — Assigns the input module's signal to the console's
submaster and stereo master modules.
SEND controls — The module's signal can be routed to the console's four
send busses via these rotary controls; each send control can tap the module
signal PRE or post fader via individual switches. Note the Send function may
be programmed to follow the module's ON/OFF switch (see "Internal Control").
PK peak LED indicator — Lights to show overload conditions within the
module's circuitry (monitors both pre and post fader signals).
SIG LED signal indicator — Lights to indicate signal presence.
READY LED — A tally indicator that can be lit from an external source or
location.
SOLO switch — Sends the modules post-fader signal to the console's solo
bus, where it may be programmed to automatically interrupt contol room and/
or headphone monitor ouputs
CUE switch — Sends the module's pre-fader signal to the console's solo bus,
where it may be programmed to automatically interrupt control room and/or
headphone monitor outputs (see 'Monitor Modules" chapter)
MUTE ASSIGN switches — The SP-8 console has two master mute
switches (A & B, located on the stereo master module). Individual inputs may
be assigned to either of the two master mute circuits, allowing groups of
channels to be activated and de-activated with the push of a single switch.
MIX-MINUS ASSIGN switches — The SP-8 console has four mix-minus
busses; each input module may be switched to any combination of the four
busses. When a switch is activated the module's signal is "minused" out of that
particular bus's mix.
FADER — Controls the module's output level.

INPUT MODULES
Logic Functions
External Control
The MI-08 input module may be muted and placed into talkback mode from
a remote location; the module's READY indicator may also be illuminated
from a remote source.
The module's channel ON/OFF switch can also be used to trigger events at
external locations. Three functions are available: European relay start, machine
start, machine stop. An optional fader end-of-travel switch may also be used to
activate these functions
See DB-9 Control connector (page 2-5) and sheet 5 of schematic (page 2-11).
Internal Control
SEND: The module's send signals can be programmed (via internal jumpers;
see schematic sheet 3, page 2-9, D5 & C5) to follow the channel ON/OFF
switch.
CUE: An optional fader end-of-travel switch may be used to automatically
activate the module's Cue function (schematic sheet 5, C8, page 2-11).
Dipswitch Programmable Functions
The module's channel ON/OFF switch can be programmed, via an internal
PCB-mounted dipswitch, to trigger various functions within the console, as
well as events at external locations. Available functions include:
(Position 1) timer restart - (Factory Default: OFF)
(Position 2) studio mute 2 - (Factory Default: OFF)
(Position 3) studio mute 1 - (Factory Default: ON)
(Position 4) control room mute - (Factory Default: OFF)
(Position 5) on-air tally 2 - (Factory Default: OFF)
(Position 6) on-air tally 1 - (Factory Default:OFF)
(Position 7) line mute - (Factory Default: OFF)
See schematic sheet 5, B2 (page 2-11) and PCB load sheet, dipswitch
"SW18" (page 2-6).

INPUT MODULES
I/O Connections
Module microphone and line level audio inputs are via rear panel female XLR connectors
(pin 1 shield, pin 2 high, pin 3 low).
The module's patch insert points utilize 1/4" phone jacks.
Channel direct output is a male XLR connector (pin 1 shield, pin 2 high, pin 3 low).
Control connections are via a DB-9 multi-pin connector.

Front Panel Controls
From top to bottom, the individual module controls are as follows:
MIC A/B switch — Selects between microphone A and B.
MIC A GAIN pot — Continuously variable; used to match input levels from
one module to the next.
PHANT switch (two: A and B) — Switches microphone phantom power on
and off.
PAD switch (two: A and B) — Attenuates (–20dB) the signal feeding the
microphone input; used to control extremely loud source material and prevent
it from overloading the module's microphone input circuitry.
MIC B GAIN pot — Continuously variable; used to match input levels from
one module to the next.
PHASE switch — Reverses the polarity of the microphone inputs.
HPF high pass filter switch — Introduces a high pass –12dB/octave roll-off
at 125Hz; used for removing unwanted low frequency content from source
signals.
EQ — 3-band semi-parametric with one concentric control for each band.
Each band continuously variable +/–16dB with continuously variable center
frequency. Frequency ranges are high: 800Hz–16KHz; mid: 400Hz–8KHz;
low: 40Hz–1KHz. Equalization curves are reciprocal, allowing previously
applied equalization to be subsequently removed.
EQ IN switch — Switches the 3-band EQ controls in and out of the circuit
(does not affect HPF switch).
PAN pot — Pans the module's mono signal between the left and right
channels of the console's stereo output (L/R assign switch must be engaged; see
below)
BUS ASSIGN switches — Assigns the input module's signal to the console's
submaster and stereo master modules.
SEND controls — The module's signal can be routed to the console's four
send busses via these rotary controls; each send control can tap the module
signal PRE or post fader via individual switches. Note the Send function may
be programmed to follow the module's ON/OFF switch (see "Internal Control").
PK peak LED indicator — Lights to show overload conditions within the
module's circuitry (monitors both pre and post fader signals).
SIG LED signal indicator — Lights to indicate signal presence.
CHANNEL ON/OFF switch — With integral LED indicator.
SOLO switch — Sends the modules post-fader signal to the console's solo
bus, where it may be programmed to automatically interrupt contol room and/
or headphone monitor ouputs
CUE switch — Sends the module's pre-fader signal to the console's solo bus,
where it may be programmed to automatically interrupt control room and/or
headphone monitor outputs (see "Monitor Modules" chapter)
MUTE ASSIGN switches — The SP-8 console has two master mute
switches (A & B, located on the stereo master module). Individual inputs may
be assigned to either of the two master mute circuits, allowing groups of
channels to be activated and de-activated with the push of a single switch.
MIX-MINUS ASSIGN switches — The SP-8 console has four mix-minus
busses; each input module may be switched to any combination of the four
busses. When a switch is activated the module's signal is "minused" out of that
particular bus's mix.
FADER — Controls the module's output level.

INPUT MODULES
Logic Functions
External Control
The DM-08 input module may be muted and/or placed into talkback mode
from a remote location.
An optional fader end-of-travel switch is also available for channel ON and
CUE mode functions
See DB-9 Control connector (page 2-19) and sheet 5 of schematic (page 226).
Internal Control
SEND: The module's send signals can be programmed (via internal jumpers;
see schematic sheet 3, page 2-24, D5 & C5) to follow the channel ON/OFF
switch.
CUE: An optional fader end-of-travel switch may be used to automatically
activate the module's Cue function (schematic sheet 5, C8, page 2-26).
Dipswitch Programmable Functions
The module's channel ON/OFF switch can be programmed, via an internal
PCB-mounted dipswitch, to trigger various functions within the console, as
well as events at external locations. Available functions include:
(Position 1) studio mute 2B - (Factory Default: OFF)
(Position 2) studio mute 2A - (Factory Default: OFF)
(Position 3) studio mute 1A - (Factory Default: ON)
(Position 4) control room mute - (Factory Default: OFF)
(Position 5) on-air tally 2A - (Factory Default: OFF)
(Position 6) on-air tally 1B - (Factory Default: OFF)
(Position 7) studio mute 1B - (Factory Default: OFF)
See schematic sheet 5, B2 (page 2-26) and PCB load sheet, dipswitch
"SW18" (page 2-20).

INPUT MODULES
I/O Connections
Module microphone A/B audio inputs are via rear panel female XLR connectors
(pin 1 shield, pin 2 high, pin 3 low).
The module's patch insert points utilize 1/4" phone jacks.
Channel direct output is a male XLR connector (pin 1 shield, pin 2 high, pin 3 low).
Control connections are via a DB-9 multi-pin connector.

Front Panel Controls
A
From top to bottom, the individual module controls are as follows:
LINE A TRIM pot — Center detented, +/–15dB, allows continuously
variable adjustment of line input levels.
PHASE switch — Reverses the polarity of line A input.
LINE A/B switch — Selects between line input A or line input B connectors.
LINE B TRIM pot — Center detented, +/–15dB, allows continuously
variable adjustment of line input levels.
PHASE switch — Reverses the polarity of line B input.
HPF high pass filter switch — Introduces a high pass –12dB/octave roll-off
at 125Hz; used for removing unwanted low frequency content from input
source signals.
EQ — 3-band semi-parametric with one concentric control for each band.
Each band continuously variable +/–16dB with continuously variable center
frequency. Frequency ranges are high: 800Hz–16KHz; mid: 400Hz–8KHz;
low: 40Hz–1KHz. Equalization curves are reciprocal, allowing previously
applied equalization to be subsequently removed.
EQ IN switch — Switches the 3-band EQ controls in and out of the circuit
(does not affect HPF switch).
PAN pot — Pans the module's mono signal between the left and right
channels of the console's stereo output (L/R assign switch must be engaged; see
below)
BUS ASSIGN switches — Assigns the input module's signal to the console's
submaster and stereo master modules.
SEND controls — The module's signal can be routed to the console's four
send busses via these rotary controls; each send control can tap the module
signal PRE or post fader via individual switches. Note the Send function may
be programmed to follow the module's ON/OFF switch (see "Internal Control").
PK peak LED indicator — Lights to show overload conditions within the
module's circuitry (monitors both pre and post fader signals).
SIG LED signal indicator — Lights to indicate signal presence.
READY LED — A tally indicator that can be lit from an external source or
location.
SOLO switch — Sends the modules post-fader signal to the console's solo
bus, where it may be programmed to automatically interrupt contol room and/
or headphone monitor ouputs
CUE switch — Sends the module's pre-fader signal to the console's solo bus,
where it may be programmed to automatically interrupt control room and/or
headphone monitor outputs (see 'Monitor Modules" chapter)
MUTE ASSIGN switches — The SP-8 console has two master mute
switches (A & B, located on the stereo master module). Individual inputs may
be assigned to either of the two master mute circuits, allowing groups of
channels to be activated and de-activated with the push of a single switch.
MIX-MINUS ASSIGN switches — The SP-8 console has four mix-minus
busses; each input module may be switched to any combination of the four
busses. When a switch is activated the module's signal is "minused" out of that
particular bus's mix.
FADER — Controls the module's output level.

INPUT MODULES
Logic Functions
External Control
The DML-08 input module's READY indicator may be illuminated from a
remote source.
The module's channel ON/OFF switch can also be used to trigger events at
external locations. Three functions are available: European relay start, machine
start, machine stop. An optional fader end-of-travel switch may also be used to
activate channel on, machine start, or cue functions.
See DB-9 Control connector (page 2-34) and sheet 5 of schematic (page 240) for details.
Internal Control
SEND: The module's send signals can be programmed (via internal jumpers;
see schematic sheet 3, page 2-38, D5 & C5) to follow the channel ON/OFF
switch.
CUE: An optional fader end-of-travel switch may be used to automatically
activate the module's Cue function (schematic sheet 5, C8, page 2-40).
Dipswitch Programmable Functions
The module's channel ON/OFF switch can be programmed, via an internal
PCB-mounted dipswitch, to trigger various functions within the console, as
well as events at external locations. Available functions include:
(Position 1) timer restart - (Factory Default: OFF)
(Position 2) studio mute 2 - (Factory Default: OFF)
(Position 3) studio mute 1 - (Factory Default: ON)
(Position 4) control room mute - (Factory Default: OFF)
(Position 5) on-air tally 2 - (Factory Default: OFF)
(Position 6) on-air tally 1 - (Factory Default:OFF)
(Position 7) line mute - (Factory Default: OFF)
See schematic sheet 5, B2 (page 2-40) and PCB load sheet, dipswitch
"SW17" (page 2-35).

Front Panel Controls
From top to bottom, the individual module controls are as follows:
LEFT (and RIGHT) TRIM pots — Center detented, +/–15dB, allow
continuously variable adjustment of left and right line input levels.
INPUT A/B switch — Selects between the A and B stereo line input
connectors.
EQ — 3-band with one continuously variable +/–16dB rotary control for
each band. Each band with switchable center frequency: high is 10KHz/5KHz;
mid 41KHz/500Hz; low 100Hz/50Hz. Equalization curves are reciprocal,
allowing previously applied equalization to be subsequently removed.
EQ IN switch — Switches the 3-band EQ controls in and out of the circuit.
BAL pot — A balance pot used to center the stereo image.
BUS ASSIGN switches — Assigns the input module's signal to the console's
submaster and stereo master modules.
MODE switch — Successive pushes on the Mode switch cause the module
to go from stereo, mono (L+R), left to both channels and right to both channels.
SEND controls — A mono version of the module's signal can be routed to
the console's four send busses via these rotary controls; each send control can
tap the module signal PRE or post fader via individual switches. Note the Send
function may programmed to follow the module's ON/OFF switch (see "Internal
Control").
PK peak LED indicator — Lights to show overload conditions within the
module's circuitry (monitors both pre and post fader signals).
SIG LED signal indicator — Lights to indicate signal presence.
READY LED — A tally indicator that can be lit from an external source
machine.
SOLO switch — Sends the module's post-fader signal to the console's stereo
solo bus, where it may be programmed to automatically interrupt control room
and/or headphone monito ouputs (see "Monitor Modules" chapter).
CUE switch — Sends the module's pre-fader signal to the console's stereo
solo bus, where it may be programmed to automatically interrupt control room
and/or headphone monitor outputs (see 'Monitor Modules" chapter)
MUTE ASSIGN switches — The SP-8 console has two master mute
switches (A & B, located on the stereo master module). Individual inputs may
be assigned to either of the two master mute circuits, allowing groups of
channels to be activated and de-activated with the push of a single switch.
MIX-MINUS ASSIGN switches — The SP-8 console has four mix-minus
busses; each input module may be switched to any combination of the four
busses. When a switch is activated the module's signal is "minused" out of that
particular bus's mix.
FADER — Controls the module's stereo output level.

INPUT MODULES
Logic Functions
External Control
The SI-08 input module may be muted and placed into cue mode from a
remote location; the module's READY indicator may also be illuminated from
a remote source.
The module's channel ON/OFF switch can also be used to trigger events at
external locations. Three functions are available: European relay start, machine
start, machine stop. An optional fader end-of-travel switch may also be used to
activate these functions. Note machine start/stop functions follow the console's
master Machine Link switch (located on the stereo output module). This switch
may be jumper-bypassed if desired.
See DB-9 Control connector (page 2-48) and sheet 5 of schematic (page 254).
Internal Control
SEND: The module's send signals can be programmed (via internal jumpers;
see schematic sheet 3, page 2-52, D5 & C5) to follow the channel ON/OFF
switch.
CUE: An optional fader end-of-travel switch may be used to automatically
activate the module's Cue function (schematic sheet 5, C8, page 2-54).
Dipswitch Programmable Functions
The module's channel ON/OFF switch can be programmed, via an internal
PCB-mounted dipswitch, to trigger various functions within the console, as
well as events at external locations. Available functions include:
(Position 1) timer restart - (Factory Default: ON)
(Position 2) studio mute 2 - (Factory Default: OFF)
(Position 3) studio mute 1 - (Factory Default: OFF)
(Position 4) control room mute - (Factory Default: OFF)
(Position 5) on-air tally 2 - (Factory Default: OFF)
(Position 6) on-air tally 1 - (Factory Default:OFF)
(Position 7) line mute - (Factory Default: OFF)
See schematic sheet 5, B2 (page 2-54) and PCB load sheet, dipswitch
"SW17" (page 2-49).

Group Submaster (MG-08)
SOLO
Each one of these group modules (there are four to a console) contains
circuitry for two submasters. They are used to master input module subgroups
before their combined signals are passed on to the console master outputs.
Group modules can be used to feed and playback multitrack recorders and can
also function as additional console outputs.

Front Panel Controls
From top to bottom, the individual module controls are as follows:
METERS — Front panel multi-turn trimpots used for group and send VU
meter calibration.
SEND pot — The master level control for, in this case, SEND 1. Group
module two houses the master level for SEND 2, and so on.
SOLO switch — Allows the master send level to be monitored on the
console's solo bus.
SOLO
R
STEREO
STEREO LINE INPUT SECTION:
BUS ASSIGN switches — Assign the stereo line return signal to the
console's submaster and stereo master modules.
BAL/LEVEL concentric pot — Controls the level of the stereo line return
signal and acts as a balance control for same when it is assigned to the console's
stereo output module.
SOLO switch — Allows the line return signal to be monitored on the
console's solo bus.
TALKBACK switches — Assign the console's talkback signal to the
SEND, MIX-MINUS and SUBMASTER ACN busses (Send 1, Mix-Minus 1
and Submasters 1 & 2).
GROUP FADER ASSIGN SECTION:
Fader 1 PAN control — Pans mono post-fader submaster signal 1 between
the left and right channels of the console's stereo output.
Fader 1 BUS ASSIGN switches — Assign post-fader mono submaster
signal 1 to the console's STEREO output and/or MONO bus.
Fader 2 PAN control — Pans mono post-fader submaster signal 2 between
the left and right channels of the console's stereo output.
Fader 2 BUS ASSIGN switches — Assign mono post-fader submaster
signal 2 to the console's STEREO output and/or MONO bus.
BUS ASSIG
SOLO 1 switch — Sends submaster 1 signal to the console's solo bus.
SOLO 2 switch — Sends submaster 2 signal to the console's solo bus.
FADERS — Control module output levels for submaster channels 1 and 2.

Front Panel Controls
From top to bottom, the individual module controls are as follows:
METERS — Front panel multi-turn trimpots used for left and right VU
meter calibration.
MACHINE LINK switch — This master switch enables source machine
start/stop functions that key off of input module ON/OFF switches. Note this
switch may be bypassed at individual input modules via an internal jumper.
MUTE ASSIGN switches — The SP-8 console has two master mute
switches (A & B, located on the stereo master module). Individual inputs may
be assigned to either of the two master mute circuits, allowing groups of
channels to be activated and de-activated with the push of a single switch.
LT CHANNEL BUS ASSIGN switch — Assigns the module's left channel
to the console's MONO bus.
RT CHANNEL BUS ASSIGN switch — Assigns the module's right
channel to the console's MONO bus.
LEFT SOLO switch — Sends the module's left channel signal to the
console's solo bus.
RIGHT SOLO switch — Sends the module's right channel signal to the
console's solo bus.
FADER — The master level control for the console's stereo output.

From top to bottom, the individual module controls are as follows:
TB MIC level control — Sets the console's talkback level. The talkback
microphone input XLR is located directly to the right of this control.
STUDIO SOURCE SELECT switching — This interlocked switchbank
determines which signal will be sent to the console's studio output. Selections
include the four send busses, the master stereo output, the mono bus, and two
external line inputs.
CR SOURCE SELECT switching — This interlocked switchbank is
identical to the studio source select switchbank above it. It determines which
signal will be sent to the console's control room output. Note the console's
headphone output follows this switchbank.

OSCILLATOR SECTION:
FREQUENCY switches — Determine which calibration frequency will be
generated: 10KHz, 1KHz, 100Hz, or 50Hz.
OFF switch — Turns the oscillator OFF; note an LED indicator stays lit
whenever the oscillator is ON.
OSC level pot — Controls the level of the oscillator signal.
TONE switch — When pressed, replaces the console's talkback signal with
the frequency oscillator output; it also routes same to the console's send ACN
busses.
SLATE switch — When pressed, sends talkback to the console's group and
output busses. If the TONE switch is pressed simultaneously, the frequency
oscillator signal is sent to same.

SIGNALLING SECTION:
CALL switch — When linked to a similar switch at a remote (studio)
location, lights the remote button's indicator light. Also lights up when the
remote button is pushed.
READY switch — When pressed, lights a ready tally indicator at a remote
studio location. If the studio is on-air at the time, the STUDIO button
(immediately underneath) lights up instead.
STUDIO switch — When pressed, lights an on-air tally indicator at a remote
studio location (provided the studio is on-air at the time).
STUDIO level pot — Controls the level of the console's studio output.
STUDIO MUTE ENABLE switch — When engaged, allows the studio

General Description
This option adds an overbridge control surface to the console consisting of
individual vertical panels, each containing an 8-position interlocking lighted
switchbank. These switchbanks are used to preselect program sources for the
input modules directly underneath each bank, greatly expanding the input
capacity of the console. I/O connections are made through two DB-25 (inputs)
and one DB-9 (output) connector behind each switchbank on the rear of the
console meterbridge (see pinout drawing).

BALANCED VERSUS UNBALANCED
INPUT/OUTPUT CONNECTIONS
The ability to use output HIGH or
LOW permits an easy phase reversal of the console's output
signals, should this be desired.
SP-8 / Dec 98
95
By now everyone knows (or should know) that balanced inputs and outputs
are highly desirable - they have an intrinsic ability to reject hum, noise,
crosstalk, and RF, even if the shielding and grounding leave something to be
desired. Telephone companies routinely pack hundreds of balanced lines into
one cable, with no shielding, next to AC power lines and street lights, and if
good balance is maintained, the individual circuits are completely free of noise
and crosstalk.
Not all equipment used in stations is balanced, however, and the most costeffective devices often don’t have +4 dBu output levels, either. Because of
these realities, all Wheatstone consoles are designed to accept balanced or
unbalanced sources with levels as low as -10 dBu.
Connecting unbalanced inputs is simple—wire to the console with typical
shielded two conductor cable (like Belden 9451), just as if you were connecting
a balanced source. At the unbalanced machine’s output, connect the black
wire (LOW) to the shield. This “pseudo-balanced” connection has proven to be
the simplest and most trouble-free way to go. Another plus is that the wiring
need not be changed out if a balanced output machine is subsequently
installed in that position. If the machine has a -10 dBu output, don’t hesitate
to turn your input trimmers as high as is needed.
SP-8 consoles use a new type of balanced output circuit, which behaves
exactly like the secondary of a high-quality transformer, with no center tap—
this output is both balanced and floating. Either the HIGH or LOW side of the
output should be strapped to ground, with the output taken from the other
side. (Normally you’d strap LOW to ground, and take HIGH to feed your
unbalanced equipment.)
This type of self-compensating active-balanced output has been tried
before, but it required costly hand-matching of resistors to maintain stability

and low distortion. The 2142 balanced line driver IC uses laser-trimming of
the on-chip resistors, under computer control, to achieve the desired results
at a realistic price. A major advantage over the discrete component designs is
the ability to replace the IC without the need for hand-picking resistors to
restore the performance of the circuit. If lightning ever strikes in your
neighborhood, you know that nothing is totally immune to a close hit. It’s
comforting to know that you can simply unplug the left or right output stage,
swap in another, and be back up and running in minutes.

CS-08 MODULE OUTPUT CONNECTIONS
!
Note these output connection
details differ from the SP-8's other modules (called out on the
previous page).
The SP-8 console's monitor module has electronically balanced output
circuits on its main output channels. Care should be taken when installing
or testing these circuits to avoid connecting the "low" side of these outputs
to ground or to an input circuit that has a low impedance to ground. While
such a connection will not cause damage to the console, levels will be
incorrect and distortion figures will rise. If an unbalanced connection must
be made to these outputs, let the "low" side float unconnected or else build
it out with a 620Ω or higher resistor.
NOTES ON LEVEL MEASUREMENT
Audio levels today are commonly referred to as voltage equivalents of
power levels in 600 ohm circuits. One milliwatt (0 dBm) in 600 ohms is a
voltage of .775 V. The corresponding unit for use in circuits where the exact
impedance is unknown or irrelevant is the dBu (the "u" stands for "unloaded").
Thus, 0 dBu is .775 V regardless of the impedance of the circuit where it is
measured. (Note the dBu should not be confused with the dBV; 0 dBV = 1
volt.)
For your convenience, here are some commonly encountered values:
0 dBm in 600 ohms = .775 V = 0 dBu in any impedance
+4 dBu = 1.23 V
+8 dBu = 1.95 V
-10 dBu = .245 V
-20 dBu = 77.4 mV
-50 dBu = 2.45 mV
When checking out a system, remember to measure the input voltage at the
connector, as variations in input impedance and generator source impedance
can invalidate your results.
TROUBLESHOOTING
BASIC PROCEDURES
If you have encountered difficulty in testing your installation, check the
items listed below before opening the console. Note that some items may seem
very obvious; it is often the most obvious things that we overlook.
1) Check that the AC power source for the console is live, and that the
console power cable is connected to the AC source.
2) Make sure that the sources you are using to test the console installation
are producing normal, line level signals. For example, if a cart machine is the
source, is the cart playing? Is the output of it connected to the console?
3) When checking for sound from the control room speakers, is the
amplifier on? Is the amplifier volume turned up to a normal level? Are the
speakers connected to the amplifier outputs?
SP-8 / Dec 95
Appendix Page - 3
APPENDIX
4) If you have checked external devices and connections, and feel that the
problem is within the console, double check all wiring before attempting to
troubleshoot the console itself.
Testing a "Live" (Powered-Up) Console – Precautions
(1) If a module must be removed, but remain connected while trouble–
shooting, place a piece of cardboard or other non-conducting material
across the console where the module will be placed. This will prevent
shorting, and also avoid scratching or marring the faceplates.
(2) Be extremely careful when using meter or oscilloscope test probes, to
avoid shorting a test point to an adjacent connection. This is especially
important when probing a pin 7 op-amp output, since the adjacent pin 8 is
at 18 volts.
(3) NEVER remove or insert an integrated circuit while the console is
powered up.
INTEGRATED CIRCUITS
A polyswitch is a device that
switches to a very high impedance state when it's current
threshold is reached. The device
resets to a very low impedance
state when the fault condition is
cleared.
The audio circuits of the console consist almost entirely of plug-in IC opamps. The types called out in the schematic drawings and parts lists are
chosen for optimum performance; in an emergency situation other types of
known matching pin-out and capability can be temporarily substituted. Some
useful troubleshooting hints for these circuits follow.
(1) Due to the large open-loop gain of the typical op-amp, the inverting
input of an amplifier, configured as an inverter with its non-inverting input
grounded, acts as a “virtual ground,” and signal levels at this point can be
expected to be extremely low. However, a circuit fault could result in a large
signal level at the inverting input, so it may be worth checking.
(2) When one of these ICs fails, it commonly swings its output to one of
the power supply rails. This should be a first check when a bad IC is
suspected. Measure the output pin of the IC directly (as opposed to
measuring after a coupling capacitor) under a no-signal condition and look
for a large DC offset at the output. Note SP-8 input, group and output
modules are power-protected from the main voltage distribution busses by
means of electronic fuses ("polyswitches") that automatically isolate the
module from the rest of the console in the event of a voltage failure. These
will reset once the fault is corrected and they have cooled off.
!
The SP-8 Control Room/Studio module does not have polyswitches; it is
protected by 3.3Ω fuse resistors which will generally become open circuits
when an IC fails, often with no visual indication. Whenever a fault is
suspected check the voltage on the module side of these resistors. If one
needs replacement be sure to stand it up from the circuit card as it can
become hot enough to burn the card under fault conditions. In a pinch any
low value 1/4 watt resistor can be used.
(3) The capacitive loading effect of a test probe may occasionally cause
oscillations in a high gain amplifier circuit. For this reason it is advisable,
when using meter probes to measure DC voltage in an amplifier circuit, to
isolate the “hot” lead from the circuit under test with a 10K resistor. This

introduces a slight measurement error, depending on the meter input
impedance, but this error is slight compared to the error that occurs if the
amplifier is oscillating. If signal tracing with an oscilloscope, use a low
capacity probe.
(4) Because of the feedback loop in the op-amp circuit, sometimes a signal
can be measured or heard even when the IC is defective or even removed.
Generally this signal will become more and more distorted as the level
increases; also the gain of the affected path will be incorrect. Don’t assume
that because you can observe an output signal the IC must be working
properly.
OTHER DETAILS
(1) In general, SP-8 consoles are rugged and user friendly. I/O connections
can be unplugged or plugged in while powered up with no damage, provided
the precautions described above concerning removal and replacement of
modules are carefully followed. Occasionally, this will cause a transient in
the logic system that may be sufficient to affect a channel’s ON/OFF status,
but this is rare.
(2) If the power cable is being unplugged from the mainframe or the power
supply, be sure to first turn the power off to avoid arcing the connector pins.
(3) The module faceplate Lexan panel overlays are very durable, and can be
easily cleaned with Windex. If they should become burned or torn through
carelessness they can be replaced; consult Wheatstone for details.
(4) Care should be taken with the plexiglas covering the VU meters, as it is
easily scratched.
(5) Fader knobs should be removed or installed only when the fader is at the
end of its travel, to avoid "bowing" the internal fader structure.
Wheatstone maintains an active program of user support and technical assistance. You are encouraged to call (252-638-7000) or fax (252637-1285) the factory with any questions, problems, ideas, or
suggestions regarding your SP-8 console.

FURNITURE LEG SET ASSEMBLY INSTRUCTIONS
The SP-8 furniture leg set is shipped in four sections:
a) two wooden side pieces
b) a front panel
c) a rear panel
Note the leg set has already been pre-assembled with the SP-8 console
at the factory, so all holes have been predrilled. The set is subsequently
broken down for shipping purposes. All that remains at the client end is reassembly.
a) Note the wooden side pieces: the curved edges face towards the front; metal
brackets have been pre-mounted on their inside surfaces; the bottom edge of each
piece is longer than the top edge. When set upright in the correct orientation, the
distance between them will equal the width of your SP-8 audio console, and the
front and rear vanity panels will span that distance.
b) The front vanity panel has its formica surface facing to the front; the cherry
strip is its bottom edge and rests on the floor.
c) The rear vanity panel has its formica surface facing to the rear. The cherry
strip is its bottom edge; when in place it leaves a 3/4” gap between it and the
floor. This is for wiring cable access.

FIELD ASSEMBLY CONSISTS OF FIVE BASIC STEPS:
1) Position the two side pieces and mount the FRONT VANITY PANEL
to them, by screwing through the side piece front metal brackets directly into
the predrilled holes on the front panel’s surface, using the wood screws
provided.
2) Mount the REAR VANITY PANEL to the rear metal brackets of the
side pieces. Note this panel is attached using finished cupwasher screws that
go into pre-tapped holes on the side pieces’ rear metal brackets. Remember
there will be a 3/4” gap between the rear panel’s cherry trim strip and the
floor.
3) With all screws tightened and the leg set safely assembled as a squared
rigid structure, it is time to place the SP-8 console onto the leg set.
When properly in position (see drawing next page) the console’s
wooden endpieces will rest on the leg stand’s side pieces, and will span the
rear vanity panel. Front to rear position is determined by the predrilled holes
in the bottom of the console’s mainframe.
4) With the console in place and properly positioned, remove the REAR
VANITY PANEL. This will allow you to get inside the leg stand and screw
up through the wooden flange on top of the front vanity panel into the bottom
of the console mainframe.

5) Final step: screw up through the two top side brackets into the predrilled
holes in the bottom of the console’s mainframe.
With the console now firmly attached to the leg stand, it is safe to do wiring.
Then replace the rear vanity panel.
