🎶 Gecko IN.STREAM 2 Audio System (Quick Connect Cord) — Spa Audio Station for Y Series Control Systems

Stream music wirelessly, play USB tracks, tune into FM radio, or plug in any device — all controlled from your Gecko keypad without leaving the water

📋 Product Overview

The Gecko IN.STREAM 2 is a dedicated spa audio station that combines Bluetooth streaming, USB playback, FM radio, and auxiliary input into a single splashproof unit, powered by efficient Class-D amplifiers delivering up to 300 watts peak output. Unlike general-purpose outdoor speakers, the IN.STREAM 2 integrates directly with your Gecko spa control system, giving you complete audio management — source switching, volume, track navigation, and display of song information — right from your spa-side keypad.

This listing is the Quick Connect cord version (Part #0704-121008), pre-cabled with three flat female quick connect tabs for direct connection to Gecko Y series spa packs: in.yj, in.ye, and in.yt control systems. If your spa uses a Gecko IN.XM2 or IN.XE control system, you need the in.link cord version (Part #0704-121007 / SKU: AV-AE001) instead.

The audio unit itself is identical across both versions — same amplifier, same features, same specifications. Only the connection cable to the spa pack differs. The IN.STREAM 2 drives up to four speakers and a dedicated subwoofer channel, all housed in a fully IPx5 splashproof enclosure with a built-in universal power supply (100–240V AC) that works anywhere in the world without external transformers.

Speakers and subwoofer are not included and must be purchased separately.

🎵 Audio Sources & How They Work

The IN.STREAM 2 provides four independent audio sources. When connected to a compatible Gecko keypad, you switch between them directly from the spa-side display. In standalone mode (no keypad connected), the unit defaults to Bluetooth.

Bluetooth Streaming — Pair any Bluetooth-enabled device (smartphone, tablet, laptop) to stream from Spotify, Apple Music, internet radio, podcasts, or any audio app. Uses Bluetooth 4.1 with A2DP for high-quality stereo audio and AVRCP for track control from your keypad. Pairing PIN is 5555. The unit remembers up to 8 devices and auto-reconnects with the last three when in range.

USB Flash Drive — Insert a USB flash drive (8–32 GB, FAT32 formatted) with MP3 files in the root directory. The USB port also charges smartphones and mobile devices at 1A.

FM Radio — Integrated receiver covers the standard 87.5–107.9 MHz band with stereo multiplex decoding. The included 1-metre cable antenna connects via 3.5mm jack. Best reception when mounted vertically and fully deployed.

Auxiliary Input — Connect any device with a standard 3.5mm headphone output directly via the auxiliary stereo jack. Supports input levels up to 2.2 Vpp.

🔌 Compatibility Guide

Quick Connect vs in.link — Which Version Do You Need?

The IN.STREAM 2 audio unit is identical in both versions. The only difference is the connection cable to the spa pack. Choosing the wrong version means the cable will not physically connect to your spa pack.

Version	Part Number	SKU	Compatible Spa Packs
Quick connect cord (this listing)	0704-121008	AV-AE002	in.yj, in.yj-3, in.ye, in.ye-3, in.ye-5, in.yt, in.yt-7 (Y series)
in.link cord	0704-121007	AV-AE001	in.xm2, in.xe (X series)

How to identify your connection type: Check the CO (communication) port on your spa pack. Y series packs use quick connect tabs (flat spade-style connectors). X series packs use the in.link connector (a rectangular multi-pin plug). If you are unsure which spa pack you have, look at the label on your control box or contact Parts4Tubs with your spa make and model.

Compatible Keypads

Full audio control (source selection, volume, track navigation, settings) is available through these Gecko keypads:

Keypad	Type	Audio Control
in.k500	Colour LCD, 7 keys	✅ Full control
in.k800	Colour LCD, 10 keys	✅ Full control
in.k1000	Colour capacitive touchscreen	✅ Full control
in.k1001	Colour capacitive touchscreen	✅ Full control
in.k175	Dedicated audio keypad (standalone)	✅ Standalone audio control

Press the Mode key on your keypad to access the IN.STREAM 2 audio controls. The audio menu only appears when the IN.STREAM 2 is connected and detected by the spa pack. Only audio sources that are physically installed appear in the source selection menu.

Standalone Operation

The IN.STREAM 2 works without any keypad or spa control system. In standalone mode, it powers on and defaults to Bluetooth. This suits installations where the unit is used purely as a Bluetooth amplifier without Gecko system integration.

🛠️ Installation Requirements

Positioning

The IN.STREAM 2 must be installed on a vertical surface to prevent water ingress. Key requirements from the official TechBook:

Mount at least 100 mm (4 inches) above the potential flood level. Maintain at least 19 mm (¾ inch) clearance at the back for heat circulation. Do not use foam insulation in front of the unit. Place away from radio noise sources such as variable speed motor controllers. Install the FM antenna vertically and fully extended for best reception.

Mounting Options

Three methods are available: direct mounting to wall studs using four #10 screws with washers; standard flat aluminium wall mount bracket (Part #9920-101474) for back-wall mounting; or Z-bracket (Part #9920-101478) for flush-mounting on the spa access door frame edge.

Electrical Connections

The built-in universal power supply (100–240V AC, 50/60 Hz) connects to a direct AC output on your spa pack. The CO cable (quick connect) plugs directly into the CO port on your Y series spa pack for keypad integration. The IN.STREAM 2 connects via the CO chain — if you also have other CO accessories (such as IN.CLEAR or IN.TOUCH 2), they connect in series on the same CO port.

Speaker Wiring

Speakers and subwoofer connect via the 10-pin MATE-N-LOK connector. No speakers or wiring are included — all speaker interconnection must be Class 2 rated and installed by qualified personnel. Optional adapter cable (Part #9920-401425) converts the 10-pin to the 3×4-pin format common in spa audio systems, with separate 1×2-pin subwoofer connector (Part #9920-401428).

⚠️ Important: Turn off all power before servicing or modifying any cable connections. Do not remove enclosure screws — no user-serviceable parts inside. All installation and wiring must be performed by qualified personnel. Do not operate audio controls while inside the spa.

❓ Frequently Asked Questions

Q: What’s the difference between this (AV-AE002) and the in.link version (AV-AE001)? A: The audio unit is identical — same amplifier, speakers, features, and specifications. The only difference is the connection cable. This Quick Connect version (Part #0704-121008) connects to Gecko Y series spa packs (in.yj, in.ye, in.yt). The in.link version (Part #0704-121007) connects to Gecko X series packs (in.xm2, in.xe). You must choose the version matching your spa pack’s CO port type.

Q: Does this system come with speakers? A: No. The IN.STREAM 2 is the amplifier and audio source unit only. You need compatible speakers (up to four, 4–8 Ohm) and optionally one subwoofer (2–4 Ohm), purchased separately. All speaker wiring must be Class 2 rated and installed by qualified personnel.

Q: Can I use this without a Gecko spa control system? A: Yes. The IN.STREAM 2 operates in standalone mode without any keypad or spa pack, defaulting to Bluetooth. However, USB playback, FM radio, and full audio controls require a compatible Gecko keypad. The in.k175 standalone audio keypad is available separately for installations without a Gecko spa pack.

Q: How do I pair my phone via Bluetooth? A: Open Bluetooth settings on your device, select “in.stream 2” from discoverable devices, and enter PIN 5555 when prompted. The system stores up to 8 paired devices and automatically reconnects with the last three when in range.

Q: I have other Gecko CO accessories (IN.CLEAR, IN.TOUCH 2) — can I use them all? A: Yes. CO accessories connect in a daisy-chain on the same CO port of your spa pack. The IN.STREAM 2 has spare CO sockets to pass the connection through to additional accessories in the chain.

Q: What USB drives are compatible? A: USB flash drives between 8 GB and 32 GB, formatted as FAT32. Supports USB 1.1, 2.0, and 3.0. MP3 files must be in the root directory (not in subfolders). The USB port also charges mobile devices at 1A.

Q: Can I install this outdoors? A: The IN.STREAM 2 is IPx5 rated (splashproof) and designed for installation under the spa skirt or in a protected area. It must be mounted on a vertical surface at least 100 mm above flood level. It is not designed for direct rain exposure or submersion.

Q: Can I update the firmware? A: Yes. Field firmware updates are supported via USB flash drive (8–32 GB, FAT32). The update takes approximately 3 minutes. Never disconnect power or remove the flash drive during the process — doing so can render the unit unbootable.
