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.

(8) Re-attach the console rear concealment panel.

THE CONSOLE POWER SUPPLY

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".

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.

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 - 7

Page 1 - 5

The aforementioned "isolated

AC ground" (orange studio

outlet; see page 2-2) can also

be used to accomplish the

required grounding.

I

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.

NSTALLATION

Once the system is properly grounded, you may proceed with the audio
and control input/output connections (next chapters).

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.

+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.

P

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;

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/

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.

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).

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

low: 40Hz–1KHz. Equalization curves are reciprocal, allowing previously

applied equalization to be subsequently removed.

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/

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.

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 2-

26).

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).

Front Panel Controls

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;

P

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)

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

MUT
GROU

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.

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 2-

40) 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).

I/O Connections

READY+

TB/CUE IN

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.

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

particular bus's mix.

FADER — Controls the module's stereo output level.

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 2-

54).

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)

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:
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.

STUDIO TB switch — Activates talkback, sending it to the console's studio

output.

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

output to be muted by the console's logic circuitry.

SOLO level pot — The master level control for the console's solo circuit.
HDPN level pot — Controls the level of the console's headphone output.
HDPN SOLO ENABLE switch — When engaged, allows the headphone

output to be interrupted by solo.

CR level pot — Controls the level of the console's control room output.
CR MUTE ENABLE switch — When engaged, allows the CR output to be

muted by the console's logic circuitry.

CR SOLO ENABLE switch — When engaged, allows the control room

output to be interrupted by solo.

HDPN jack — The output jack for the console's built-in headphone amp.
