APB-DynaSonics MONO INPUT - BUS ASSIGNMENT AND PANNING Pan Control This control blends the post-fader signal between any of the assigned bus pairs: L-R, Group1-2 and Group 3-4. When at the center, detented position, both sides are fed equal amounts of signal (each down by 3dB). -
Page 17: Mono Input - Rear Panel Connectors
ProDesk-4 OWNER’S MANUAL MONO INPUT - REAR PANEL CONNECTORS 1/4” TRS Direct Output Connector The connector provides an impedance-balanced line level output of the input channel’s signal. The default Direct Out signal is AFTER the microphone preamplifier but before all other processing. -
Page 18: Stereo Line Input
APB-DynaSonics STEREO LINE INPUT TRS/ALT (RCA OR USB) Line Input Switch Selects the stereo input source between the rear-panel 1⁄4” TRS jacks (switch UP) or the RCA connectors (switch DOWN) on Inputs A-B-C. On Stereo Input D, the USB Audio In signal is selected when this switch is depressed (there are no RCA jacks for Input D). -
Page 19: Stereo Line Input - Stereo Equalization
ProDesk-4 OWNER’S MANUAL STEREO LINE INPUT - STEREO EQUALIZATION High Frequency Level Control (Shelving) Adjusts the high frequency shelving cut/boost between +/-15dB. Boost or cut of the high frequency level control is usually used for minor tonal adjustments. Use of this EQ control will affect both the left and right signal paths. -
Page 20: Stereo Line Input - Aux Sends
APB-DynaSonics STEREO LINE INPUT - AUX SENDS Stereo Channel Aux Sends The signals feeding the Aux sends are normally summed-mono mixes of the left & right side signals within the module. For Auxes 1& 2, when switched to Stereo, the left-side channel signal feeds the Aux 1 control; the right-side channel signal feeds the Aux 2 control. -

Page 22: Stereo Line Input - Bus Assignment And Balance
APB-DynaSonics STEREO LINE INPUT - BUS ASSIGNMENT AND BALANCE Balance Control This control feeds the post-fader channel signals to any of the assigned bus-pairs: L-R, Group1-2 and Group 3-4. This Balance control has no effect on the Mono or Center mix buses. -
Page 23: Stereo Line Input - Rear Panel Connectors
ProDesk-4 OWNER’S MANUAL STEREO LINE INPUT - REAR PANEL CONNECTORS 1/4” TRS Left and Right Balanced Input Connectors Provides for balanced line level inputs to the channel’s left and right inputs. Design level is +4dBu Input impedance is 10KΩ balanced The input signal may be balanced or unbalanced. -
Page 24: Master Section
Aux Master Controls ProDesk-4 is equipped with 6 Aux buses. The master controls for the first 4 Auxes are located above the 4 Group master faders; the remaining 2 Aux master controls are located above the Main output faders. They all share similar controls, but Aux-6 also has the additional feature of Fader-Flip with the Mono output. -
Page 25: Group Output (1 Thru 4)
Group Master Controls ProDesk-4 is equipped with 4 Group buses. These groups can be used as audio subgroups for combining and processing a collection of input channels. These processed channels can then be added to any of the main mix buses or fed directly to the Matrix section, pre or post fader. -
Page 26: Matrix Output (1 Thru 4)
MATRIX OUTPUT (1 thru 4) Matrix Master Controls ProDesk-4 is equipped with 4 Matrix buses. Each Matrix can be a mixture of any of the 4 Groups or Main output buses, along with an individual external input. Since each Matrix can be individually configured for use, the outputs can be used as the main system feeds for the PA, or as supplimental feeds for under-balcony speakers or guest rooms. -
Page 27: Main Output (L-R-C-M)
Main-Bus Master Controls ProDesk-4 is equipped with 4 Main mix buses: Left, Right, Center and Mono. These 4 buses are typically used as the main outputs of the console. These buses also can feed the Matrix section as well as the Monitor and Record Out sections for generating additional outputs from the Console. -

APB-DynaSonics REAR PANEL CONNECTIONS (for all 18 major buses) Bus-Input (Main, Group & Aux) or External Input (Matrix): 1/4” Balanced TRS: Tip= Input+, Ring= Input–, Sleeve= Chassis A 1/4” TRS (10kΩ) balanced line input is provided for each bus. For the Main, Group and Aux buses, this balanced input directly feeds the corresponding mix bus. -
Page 29: Stereo Program In
ProDesk-4 OWNER’S MANUAL STEREO PROGRAM IN Stereo Program In This section serves as a general-purpose, stereo input into the console. Any of the 3 sources can be selected as the input signal; all selected sources are summed together. The resulting signal can be EQ’d and assigned to any of the Main buses, the Matrix, and Aux 1-2 pair. -
Page 30: Stereo Record Out (Alternate Out)
APB-DynaSonics STEREO RECORD OUT (Alternate Out) Stereo Record Out This section serves as a general-purpose, stereo output from the console. Any of 5 sources can be selected as the input signal, all selected sources are summed together and can be globally set to be pre or post their individual output controls. A Sum- Mono button provides mono compatibility. -
Page 31: Rear Panel Connections For Stereo Program In And Stereo Record Out
USB Audio In & Out The ProDesk-4 will appear as a USB-peripheral to your computer; there is on onboard circuitry (CODEC) that allows 2-way stereo communication via USB. Simultaneous record and playback of audio is possible using commonly available software. -
Page 32: Monitor / Headphone Control
MONITOR / HEADPHONE CONTROL ProDesk-4 is equipped with a comprehensive system to allow the operator to accurately monitor signals within the console. Multiple sources can be selected and combined for listening, and the Solo system permits selected inputs and ouputs to be monitored and metered. -
Page 33: Solo System- Monitor And Control
ProDesk-4 OWNER’S MANUAL SOLO SYSTEM- MONITOR and CONTROL When the Solo system is active (a PFL or AFL button is pressed), the Solo audio interrupts the default audio to the Headphone and Monitor output (unless a Solo Off button is depressed). You can listen to the Solo’d signal through the monitor system and also view the signal level on the Solo meters. -
Page 34: Talkback System
APB-DynaSonics TALKBACK SYSTEM The Talkback system allows the operator to selectively assign external audio or internal test signals to the console buses. A front-mounted XLR jack (located under the armrest) is provided for connection to a microphone or other low-level audio feed; internal sources include a “pinkish” noise generator and a 1kHz oscillator. -
Page 35: Solo-Linking And Mute-All
ProDesk-4 OWNER’S MANUAL SOLO-LINKING and Mute-All Solo Linking The ProDesk can connect to other consoles using the Bus Input and Output jacks; this allows the user to combine the audio from multiple consoles to create a larger overall mixer. APB consoles are equiped with Solo Linking connectors to also tie the Solo systems of the combined consoles together. -
Page 36: Mute-All Configuration
APB-DynaSonics Mute-All Configuration The different Modes for the Mute-All function are set by adjusting the position of the 4 removable jumpers (shunts) located behind the Phoenix connector on the circuit board. Two of the jumpers (Jumpers 1&2) determine if the Mute-All connector is internally DC powered or totally opto-isolated and activated by an external voltage. -
