Input Connections

Rear connections

The 1073SPX-D features independent rear mounted female XLR connections for microphone or line level inputs.

The rear connections are ideally suited for studio integration into patch bays or direct connections to studio microphone snakes and line-level equipment such as audio interface outputs.

The two Rear connections are the default inputs for the 1073SPX-D.

FRONT Switch

The FRONT switch activates the front mounted Combi Mic/line/DI connector and disables the rear XLR input connections.

Toggling the FRONT switch allows for easy access to the unit via the front combi input, without disconnecting the integrated rear inputs.

Front input Connections

Microphone Input (XLR Connection)

Connect microphone sources via an XLR cable to the front combi input.

Line/DI Input (TRS Connection)

Connect line or instrument sources via a TRS/TS jack cable to the front combi input.

DIGI

The DIGI switch activates the digital line input, fed from DAW output 3 named Neve Out 3 (Digi/Mon 3).

This input is designed so that the 1073SPX-D can act as a USB or ADAT hardware insert by sending DAW signals directly into the SPX-D line preamp.

When DIGI is depressed, front & rear analogue line inputs (XLR & TRS/TS) are bypassed and only the digital input is fed to the 1073 Line preamplifier.

The 1073 SPX-D features the legendary 1073 preamp, complete with transformer-balanced topology and multiple gain stages for all input types.

Gain Switch

The 1073SPX-D gain switch is used to select the input type (Mic or Line) and set the preamp gain level for the selected input.

Preamp gain is incremented in 5dB steps, ranging from -20 to +10 of line level, and -20 to -80dB of microphone level.

The line preamp has seven gain settings, selectable from the gain switch. In each of these positions, the rear XLR or front TRS line input is selected via the FRONT switch setting.

The microphone preamp has 13 switch settings, selectable from the gain switch. In each of these positions, the rear XLR or front XLR microphone input is selected via the FRONT switch setting.

There are two 'off' positions. The first off position deactivates the line preamp before switching to the microphone preamp.

The second 'off' position denotes the point in which the first single-transistor gain stage is deactivated, and the second, dual-transistor gain stage is activated.

At higher gain settings, a greater degree of harmonic saturation can be achieved by adjusting the output gain via the O/P Level into the DAW.

Phantom Power (+48v)

The +48V switch activates phantom power for the front & rear XLR microhpone inputs. When activated, the red LED will illuminate.

Dynamic microphones such as SM58's and Ribbon microphones do not require phantom power (+48v).

The +48V switch should be switched off for dynamic and ribbon microphones.

Condenser Microphones require Phantom power.

The +48V switch should be switched on for condenser microphones.

Note: Before activating Phantom Power, ensure that the monitor level is turned down to protect your monitoring system from pops.

Lo-Z

Lo-Z Switches the front or rear microphone input impedance from the default 1.2kΩ setting to 300Ω impedance.

This switch should be used to impedance match the microphone preamp to the connected microphone.

Most modern microphones use higher impedance settings, so the default 1.2kΩ setting should be used.

Vintage microphones may use lower impedances, so the Lo-Z setting of 300Ω should be used.

Note: Always check your microphone output impedance settings before activating lo-Z

DI

The DI Switch activates the front TRS DI instrument preamplifier input.

When depressed, instruments can connect to the front TRS combi connector via a 6.35mm TS or TRS jack cable.

The DI input has a high impedance of 2MΩ. DI signals pass through the microphone transformer and mic preamp stage of the 1073SPX-D.

To apply gain to an instrument DI, set the 1073SPX-D gain switch to the microphone input side of the switch, and adjust gain accordingly.

NOTE: When DI is depressed, all other microphone inputs are automatically disconnected

-20

The -20 switch Provides 20dB of attenuation to the DI input, accommodating 'hot' instrument signals.

In the default position (-20 off) the input impedance of the DI input is approximately 2MΩ .

When set to -20dB attenuation (-20 depressed) the input impedance of the DI input is approximately 200kΩ .

EQ Section

The 1073SPX-D uses a three-band inductor-based EQ circuit, identical to the classic 1073 80-series modules. The EQ circuit also includes a choke-based high pass filter.

EQ Switch

The three-band EQ and HPF are activated via the EQ switch. Unless EQ is switched, the EQ and HPF are completely bypassed.

High Frequency

The high EQ band control provides smooth +/-16dB of fixed frequency shelving EQ at 12kHz.

Mid Frequency

The mid EQ band control provides smooth +/-18dB of peaking EQ with a fixed Q.

The second ring of the dual concentric control is a switched frequency selector, ranging from 0.36, 0.7, 1.6, 3.2, 4.8, & 7.2kHz.

In the ‘off’ position, the mid EQ band is bypassed.

Low Frequency

The Low EQ band control provides smooth +/-16dB of shelving EQ.

The second ring of the dual concentric control is a switched frequency selector, ranging from 35, 60, 110, & 220Hz.

In the ‘off’ position, the low EQ band is bypassed.

High Pass Filter

The HPF is a switched rotary control used to activate an 18dB per octave high pass filter into the 1073SPX-D signal path.

Corner frequencies are selectable at 50, 80, 160 & 300Hz.

In the 'off' position, the HPF is bypassed.

Output Connections & Controls

Phase

The Phase switch reverses the phase of the 1073SPX-D output signal. In the default position, absolute phase is preserved through the unit. When Phase is depressed, the output signal of the unit is inverted by 180 degrees.

Insert Send & Return Connections

The insert send and return TRS connections are balanced at +4dBu, allowing for connection to professional audio equipment such as compressors etc.

INS

The INS Switch activates the rear TRS insert send/return loop into the SPX-D signal path.

PRE

When depressed, the PRE switch positions the insert send/return loop before the 1073SPX-D EQ circuit (pre-EQ).

In the default position, the insert loop is positioned immediately after the EQ circuit (post-EQ).

Line O/P

The Line O/P male XLR connection is the main analogue output of the 1073SPX-D.

Connect the Line output to an available line input on your audio interface to record SPX signals into your DAW.

O/P Level

Adjusts the output audio level fed to the XLR output.

This control is post-EQ but pre-output transformer.

The pot ranges from -inf to +5dB, the thick line on the graticule indicates the point of nominal unity gain.

Metering

The 1073SPX-D features a 7-stage LED PPM meter ranging from -30dB to +24dBu.

Metering can be fed from three sources, selected by pressing O/P LEVEL.

I/P – Displays metering just after the preamp gain switch.

EQ – Displays metering after the EQ & Insert send/return loop circuit.

O/P – Displays metering after the output level control.

In addition to the 7-stage LED meters, each of the meter source LEDS (I/P, EQ, O/P) include clip indication and will illuminate red if their respective signal source is close to clipping.

Monitor Connections & Controls

Monitor Input

The two monitor in L and monitor in R connections are used to input a stereo monitor source into the 1073SPX-D analogue monitor path.

These connections are ideally used as monitor connections from an external audio interface, providing an additional monitor attenuator control via the HP/LS level pot.

HP/LS level must me set to MON to activate the stereo analogue monitor path.

Monitor Output

The two monitor out L and R connections are used as the main stereo monitor output for the 1073SPX-D.

These connections are designed to connect to active studio loudspeakers or amplifiers.

HP/LS Level

The HP/LS Level control is a full range attenuator ranging from 0dB at the fully clockwise position to -inf at the fully counter-clockwise position.

The HP/LS Level control features a centre détente at the 12-o-clock position. This position is set at -10dB from the maximum output level and is ideally set as an 85dB SPL calibration point for your studio loudspeakers.

This control attenuates the Stereo XLR monitor outputs and the TRS headphone outputs in parallel.

Monitor CUT

Monitor CUT can be activated by short-pressing the HP/LS Level pot. When depressed CUT will disable the stereo monitor L&R XLR outputs. The TRS HP output will remain un-cut.

Monitor Source Selection

Long pressing the HP/LS Level pot selects between the four available monitor sources detailed below.

SPX- The output of the SPX-D channel strip is fed equally to the left & right stereo monitor outputs as a mono signal.

DAW- The output of the DAW/computer is fed into the left & right stereo monitor output as a stereo signal.

BLEND (SPX/DAW) - A blend of mono SPX-D output and stereo DAW input is fed into left & right stereo monitor outputs. When both SPX and DAW LEDs are illuminated, the BLEND pot is engaged.

MON - The stereo analogue monitor input is fed into the stereo left & right monitor outputs.

Blend

The blend control is used to crossfade stereo DAW and mono SPX signals into the 1073SPX-D stereo monitor path. This pot is designed to allow for latency-free monitoring when tracking through the 1073SPX-D.

• At the centre position, DAW and SPX signals are each attenuated by 6dB.
• At the maximum, counter-clockwise position (DAW) the SPX signal is fully attenuated, and only the stereo DAW signal is present at the stereo monitor output.
• At the maximum, clockwise position (SPX) the DAW signal is fully attenuated, and only the mono SPX signal is present at the stereo monitor output.

A long press of the BLEND pot changes the stereo DAW signal from output 1/2 to output 3/4.

This switch allows two independent stereo mixes to be selected and sent to the headphones or stereo monitors.
