Quagliardi QUAG-CHSTRP 500 Series Channel Strip Preamp Compressor EQ Bundle

Quagliardi QUAG-CHSTRP 500 series channel strip bundle

501+ Preamp: Transparency and Character in One Module

The 501+ preamp delivers a transparent response at low and mid gain settings, revealing a warm, colorful tone when pushed into saturation. Equipped with a permalloy transformer and 2520-style op amp, the 501+ provides the foundation for professional signal capture with the flexibility to add character when desired.

A front-panel combo connector accepts balanced signals or high-impedance instruments, making the 501+ equally capable with microphones, line-level sources, or direct instrument connections. The combination of custom transformers and discrete amplification creates rich harmonic content that enhances sources without masking their natural character.

 Quagliardi 576 FET compressor UREI 1176 inspired

576 FET Compressor: Precise Dynamics With Vintage Soul

Inspired by the iconic UREI 1176, the 576 FET compressor uses BF245 transistors in a hybrid design that combines vintage character with modern flexibility. Intuitive controls make it easy to dial in everything from subtle glue to aggressive pumping, while the parallel compression function allows you to blend compressed and dry signals for maximum impact.

Custom transformers throughout the signal path add musicality and depth, while stereo link capability makes the 576 excellent for both tracking individual sources and mix bus processing. The assertive sound of the 576 helps sources cut through dense mixes without requiring excessive makeup gain or additional processing.

 Quagliardi 523 ParaShelving EQ parametric shelving

523 ParaShelving EQ: Versatility and Musicality in Two Bands

The 523 ParaShelving EQ combines parametric and shelving topologies with two fully adjustable bands, offering exceptional tonal control in a compact format. Each band can be switched between parametric mode for surgical frequency targeting or shelving mode for broad tonal shaping, giving you the right tool for any equalization task.

True Bypass function allows you to completely remove the EQ from the signal path when not needed, while the BLUE circuit adds harmonic coloration and punch to the signal when engaged. This combination of precise EQ control and vintage-style saturation makes the 523 equally effective for corrective and creative applications.

Shipping & Returns

  • We deliver all US orders in 3–5 business days
  • Free cancellations
  • Returns accepted within 30 days (unused items)

Order Confirmation

Once your order is placed, you will receive an order confirmation email. This confirms that we have received your order and have pre-authorized your credit card for the purchase. After confirming availability with our suppliers, we will proceed accordingly:

  • If your item is available and ready to ship within 1–2 business days, we will process the charge and arrange for shipment.

  • If your item is on backorder or unavailable, the pre-authorization will be voided and you will be notified by email.

  • Please note: While most items ship out within 1–2 business days, total delivery time is typically 3–5 business days, depending on your location and carrier handling.

Order Shipment

If your item is in stock and your payment has been processed, your order will typically ship within 1–2 business days. Total delivery time is approximately 3–5 business days from the date of order. Once shipped, you will receive tracking information at the email address provided during checkout within 24 hours of dispatch.

If you have not received tracking information within 3–5 business days of placing your order, please contact us at support@proaudioreserve.com.

The Distributor-Direct Advantage

To ensure you receive the most recent hardware revisions and 100% factory-sealed units, Pro Audio Reserve utilizes a Distributor-Direct fulfillment model. Unlike big-box retailers that may ship "floor models" or gear that has been sitting in general-purpose warehouses, your equipment is pulled directly from the primary manufacturer hub, serialized, and dispatched. This process ensures the highest level of quality control for professional-grade recording equipment.

Shipping Policy

We currently offer free shipping within the United States only. If the checkout process on our website allows you to enter a shipping address and complete your order, your location is eligible to receive delivery.

Changing Shipping Address

If you need to change your shipping address after your order has been processed or shipped, we will do our best to accommodate the request. Please note that address changes may result in delivery delays. Any additional costs incurred due to address changes, including carrier fees or rerouting charges will be the responsibility of the customer. No exceptions.

Shipping Times

All shipping times provided are estimates and should not be considered guarantees. Most orders ship out within 1–2 business days from the time payment is processed. However, total delivery time is typically 3–5 business days, depending on your location, carrier performance, and supplier fulfillment timelines.

We work closely with our vendors to ensure timely deliveries, but please note that supply chain disruptions, high-demand periods, or weather events may occasionally cause delays beyond our control.

  • To avoid misunderstandings: The “shipping time” refers to the total time from order placement to final delivery, not just when the item leaves the warehouse.

  • Cancellations: If you choose to cancel your order because it has not arrived within the estimated delivery window, you may be responsible for applicable shipping charges, restocking fees, warehouse handling costs, and other related fees.

  • Chargebacks: Customers who initiate chargebacks due to shipping delays without contacting us first may be held legally responsible for losses. We strongly encourage open communication so we can resolve any delivery concerns directly and efficiently via our Atlanta-based support team.

Delivery Options

  • Threshold Shipping: Your item will be delivered to your front door, porch, garage, or a covered entryway.
