In-Depth Review: Pioneer Elite VSX-94TXH Performance
Design and Build Quality: First Impressions
The Pioneer VSX-94TXH made a strong first impression with its elegant piano gloss finish. Unlike some competitors who prominently displayed technology logos on the front panel, Pioneer opted to place these on the top edge, resulting in a cleaner and more visually appealing front aesthetic. The receiver featured a traditional layout with an input selection knob on the left and a substantial, weighted master volume control on the right, both offering a solid and tactile feel. With the front panel door closed, the design was minimalist, presenting only essential buttons for standby/on and basic control.
Opening the front panel revealed additional controls, including inputs for Video/Game 2, menu navigation buttons, tuner controls, headphone jack, USB port, and the MCACC setup microphone input. Multi-zone functions and signal type selection were also accessible behind the front panel.
Internally, the VSX-94TXH was dominated by a large EI core transformer and dual 15,000 uF capacitors, indicating a robust power supply capable of meeting the demands of its amplifier section. However, the receiver employed relatively thin aluminum heatsinks, which, while functional, were not as substantial in appearance as expected in a flagship product, especially when compared to competitors at a lower price point. This observation suggests a potential area where cost savings might have been implemented in the internal design.
Setting Up the VSX-94TXH Receiver: Ease of Use
Setting up the Pioneer VSX-94TXH presented a mixed experience. While basic speaker setup and connections were straightforward, navigating the on-screen menus proved to be less intuitive. The manual speaker setup and crossover configuration were easily accessible, followed by the auto MCACC room calibration system. Input setup, however, introduced an initial hurdle.
Connecting a CableTV box using a DVI-to-HDMI cable for video and coaxial digital audio for sound revealed a configuration quirk. Despite correctly assigning the inputs in the menu, audio from the CableTV source was initially absent. The solution was found in the “Signal Sel” function, accessible via the remote and front panel, which allowed manual selection of the audio input type (HDMI, PCM, Auto, Analog, Digital). Switching to “Digital” resolved the audio issue, and this setting was retained for subsequent use of the input.
The rear panel layout was generally organized, although some output placements appeared somewhat scattered. The abundance of legacy S-video and composite video inputs seemed excessive in a modern receiver, while the inclusion of only one HDMI output was a limitation compared to emerging standards. Four HDMI inputs were adequate for most setups but a second HDMI output would have been a welcome addition for enhanced flexibility.
A significant limitation was the absence of dedicated Zone 2 speaker terminals. While the surround back channels could be reassigned for Zone 2, this required physical cable switching and precluded simultaneous 7.1 channel and powered Zone 2 operation. This design choice limited the receiver’s multi-zone capabilities compared to competitors offering dedicated Zone 2 outputs.
Multi-Room and Zone Capabilities
The Pioneer VSX-94TXH offered multi-zone functionality but with certain limitations. For multi-room audio, the receiver was best suited for setups utilizing external amplifiers for Zone 2, the digital Zone 3 output, or when operating a 5.1 channel main theater. Running a 7.1 channel system alongside a powered Zone 2 was not practical due to the shared amplifier channels.
Zone 2 could be configured as powered (using surround back amplifiers), line-level (via Zone 2 pre-outs), or composite video output. A notable drawback was that changing the main zone audio source would interrupt audio playback in Zone 2 if Zone 2 was mirroring the main zone source.
Zone 3 functionality was provided via a digital TOSLINK output, allowing digital audio transmission to a separate AV receiver in another zone. Zone 3 supported Dolby Digital 5.1 and stereo PCM. However, shared sources like the AM/FM tuner and XM radio were not independently selectable across zones, meaning changing the tuner station in the main zone would also change it in Zone 2 if it was using the same source.
The receiver offered flexible amplifier assignment for the surround back channels, configurable for:
- Surround Back System (Normal/Default): Standard 7.1 surround setup.
- Surround Back System (Speaker B): Second set of main speakers in another room, mirroring the main zone source.
- Surround Back System (Front Bi-Amp): Bi-amping the front main speakers.
- Surround Back System (Zone 2): Powered Zone 2 operation with a discrete source selection and composite video output.
While versatile, the multi-zone implementation lacked the refinement of competitors with dedicated Zone 2 speaker outputs and independent source selection across all zones.
Advanced Setup and Menu Navigation
The Pioneer VSX-94TXH’s on-screen display and menu system were criticized for being convoluted and illogical. The menu structure did not follow a clear hierarchical organization, making navigation challenging. The reviewer noted that they resorted to the user manual more frequently with this receiver than others, not for advanced functions, but for basic navigation.
The menu prioritized the Auto MCACC system, placing it at the forefront, while manual settings were buried deeper in the structure. Menu items with obscure names like “FULL BAND PHASE CTRL” (presented in all caps for unknown reasons) and “Data Management” were positioned at the top level, adding to the confusion.
The Auto MCACC menu allowed configuration of surround back amplifier assignment and initiation of the automatic room calibration process. It offered options to customize the calibration, selecting specific tests to run. The MCACC system was praised for its comprehensive adjustments, including speaker size, crossover, channel levels, distance, EQ, and standing wave correction. The Full Band Phase Control aimed to flatten frequency response and minimize group delay, a feature that was suggested to be more impactful in less acoustically treated rooms with less capable speakers.
Manual MCACC adjustments were available for fine-tuning calibration results, including channel levels, speaker distance, standing wave correction (a 3-band parametric EQ for bass modes), manual EQ adjustment, and EQ Professional. The EQ Professional feature, accessible via RS-232 and PC software, provided a detailed graphical interface for advanced room EQ, comparable to systems like Audyssey Pro but without additional hardware costs.
The Manual SP Setup menu allowed configuration of speaker sizes, levels, distances, X-Curve, and THX audio settings for surround back speakers. The Input Setup menu, ranked low in the menu hierarchy, was crucial for routing audio and video inputs to the correct sources. It allowed assignment of digital, HDMI, component, and S-video inputs to each source button, input renaming, and 12V trigger assignments. The PDP In (SR+) feature enabled integration with compatible Pioneer plasma TVs for synchronized input selection.
The Other Setup menu provided access to multi-channel input subwoofer gain control, zone audio setup (Zone 2 or record output monitoring), SR+ setup for volume control with Pioneer plasmas, and HDMI Control (CEC) settings. Notably, simultaneous Zone 2 and “blind recording” (recording one source while listening to another) were not supported.
Remote Control Usability
The Pioneer VSX-94TXH’s remote control, model AXD7504, was a significant point of criticism. Described as cluttered and poorly designed, it featured an excessive number of small, tightly packed buttons with multi-level shift functions and a lack of backlighting. The reviewer likened its design to a scientific calculator remote, emphasizing its complexity and poor ergonomics, especially in dark home theater environments. While the buttons glowed in the dark, the multi-level labeling remained illegible without external light.
Source selection was via dedicated top-row buttons, with shifted functions for less frequently used sources. Accessing the setup menu required pressing the “Receiver” button first. The tuner offered direct frequency input via the numeric keypad, but lacked auto-scan and preset storage functionality. Programming the remote for external devices proved challenging. Pre-programmed codes for a Scientific Atlanta set-top box were unsuccessful, requiring laborious button-by-button learning. Programming a Denon DVD player using pre-set codes resulted in a non-standard power control behavior. The reviewer concluded that the remote was a major disappointment and recommended considering a universal remote for improved usability.
Pioneer VSX-94TXH: Home Media Gallery and Network Features
The Home Media Gallery feature of the Pioneer VSX-94TXH, while forward-thinking for its time, was described as slow and clunky in operation. Navigation through the network interface was sluggish, with noticeable delays between user input and on-screen response. Even the user manual for the Home Media Gallery was provided as a separate, short pamphlet, indicating its somewhat add-on nature.
Setting up the network connection was relatively simple for basic home networks using DHCP. The receiver supported WMDRM (Windows Media Digital Rights Management), requiring users to authorize the Pioneer HMG in Windows Media Player to access shared media libraries. Network setup within the HMG menu was straightforward for DHCP configurations, while manual IP configuration was also possible for more advanced setups.
